6th Grade Quizzes & Trivia

Questions and Answers
  • 1. 

    What are the products of photosynthesis?

    • A.

      Carbon dioxide and water

    • B.

      Oxygen and water

    • C.

      Oxygen and surgars

    Correct Answer
    C. Oxygen and surgars
    Explanation
    During photosynthesis, plants use carbon dioxide and water, along with sunlight, to produce oxygen and sugars. Oxygen is released into the atmosphere as a byproduct, while sugars are stored as energy-rich molecules in the plant. This process is crucial for the survival of plants and also plays a significant role in maintaining the oxygen levels in our atmosphere.

    Rate this question:

  • 2. 

    What happens during photosynthesis

    • A.

      The cell uses oxygen to make food

    • B.

      The cell uses the energy in sunlight to make food

    • C.

      The cell uses glucose to make oxygen

    Correct Answer
    B. The cell uses the energy in sunlight to make food
    Explanation
    During photosynthesis, plants and some other organisms convert sunlight into chemical energy in the form of glucose. This process takes place in the chloroplasts of plant cells, where chlorophyll captures the energy from sunlight. This energy is then used to convert carbon dioxide and water into glucose and oxygen. The glucose is used as a source of energy for the cell, while the oxygen is released into the atmosphere as a byproduct. Therefore, the correct answer is "the cell uses the energy in sunlight to make food."

    Rate this question:

  • 3. 

    How does photosynthesis benefit heterotrophs

    • A.

      It adds carbon dioxide to the air

    • B.

      It creates food that they can eat

    • C.

      It eliminates harmful sugars

    Correct Answer
    B. It creates food that they can eat
    Explanation
    Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Heterotrophs, such as animals and humans, cannot produce their own food and rely on consuming other organisms for energy. Therefore, photosynthesis benefits heterotrophs by creating food (glucose) that they can consume and obtain energy from. This process forms the basis of the food chain and provides sustenance for all heterotrophic organisms.

    Rate this question:

  • 4. 

    What captures energy from sunlight during photosynthesis

    • A.

      Solar cells

    • B.

      Stomata

    • C.

      Chlorophyll and other pigments

    Correct Answer
    C. Chlorophyll and other pigments
    Explanation
    Chlorophyll and other pigments capture energy from sunlight during photosynthesis. These pigments are located in the chloroplasts of plant cells. They absorb light energy and convert it into chemical energy, which is then used to fuel the process of photosynthesis. This energy is essential for plants to synthesize glucose and other organic molecules, which they use as a source of energy for growth and survival. Solar cells, on the other hand, are devices that convert sunlight directly into electricity and are not involved in the process of photosynthesis. Stomata, on the other hand, are small openings on the surface of leaves that allow for gas exchange but do not directly capture energy from sunlight.

    Rate this question:

  • 5. 

    Carbon dioxide enter plants through the

    • A.

      Pigments

    • B.

      Chloroplasts

    • C.

      Stomata

    Correct Answer
    C. Stomata
    Explanation
    Stomata are small openings present on the surface of leaves and stems of plants. They allow for the exchange of gases, including carbon dioxide, between the plant and its environment. Carbon dioxide enters the plant through these stomata during the process of photosynthesis. Pigments and chloroplasts are not involved in the direct entry of carbon dioxide into plants.

    Rate this question:

  • 6. 

    Plants use energy from the sun to produce carbon dioxide and surgars

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Plants do not produce carbon dioxide, they actually consume it during the process of photosynthesis. They use energy from the sun to convert carbon dioxide and water into sugars, which are used as a source of energy for the plant. Therefore, the statement that plants produce carbon dioxide and sugars is false.

    Rate this question:

  • 7. 

    Plants use energy from the sun to produce ________________ and sugars

    Correct Answer
    oxygen
    Explanation
    Plants undergo a process called photosynthesis, in which they use energy from the sun to convert carbon dioxide and water into oxygen and sugars. Oxygen is produced as a byproduct of this process and is released into the atmosphere. The sugars produced during photosynthesis are used by plants for energy and growth.

    Rate this question:

  • 8. 

    A heterotroph is an organism that cannot make its own food

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A heterotroph is an organism that relies on consuming other organisms or organic matter for energy and nutrients. Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, heterotrophs are unable to synthesize their own nutrients and must obtain them from external sources. Therefore, the statement that a heterotroph cannot make its own food is true.

    Rate this question:

  • 9. 

    Photosythesis and respiration form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmosphere

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because photosynthesis and respiration do not form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmosphere. While photosynthesis removes carbon dioxide and releases oxygen, respiration does the opposite by consuming oxygen and releasing carbon dioxide. This creates a balance between the two processes, but it does not keep the levels of water and carbon dioxide constant. Additionally, the water cycle is responsible for regulating water levels in the atmosphere, not photosynthesis and respiration.

    Rate this question:

  • 10. 

    Photosynthesis and respiration form a cycle that keeps the levels of _____________ and carbon dioxide fairly constant in the atmosphere

    Correct Answer
    oxygen
    Explanation
    Photosynthesis is the process by which plants convert carbon dioxide and sunlight into oxygen and glucose, while respiration is the process by which organisms use oxygen to break down glucose and release carbon dioxide. Together, these two processes form a cycle that maintains a balance of oxygen and carbon dioxide in the atmosphere. Through photosynthesis, plants release oxygen into the atmosphere, while respiration by organisms consumes oxygen and releases carbon dioxide. This continuous cycle helps to regulate the levels of oxygen and carbon dioxide, ensuring their relative stability in the atmosphere.

    Rate this question:

  • 11. 

    Small openings called ____________________ allow carbon dioxide to enter a leaf

    Correct Answer
    stomata
    Explanation
    Stomata are small openings found on the surface of leaves that allow for the exchange of gases. They regulate the intake of carbon dioxide and the release of oxygen during photosynthesis. These microscopic openings are surrounded by specialized cells that control their opening and closing, thereby regulating the flow of gases into and out of the leaf.

    Rate this question:

  • 12. 

    Plants make their own food using energy that comes from the ____________________

    Correct Answer
    sunlight
    Explanation
    Plants have a unique ability called photosynthesis, where they convert sunlight into energy through a process that involves capturing the energy from sunlight and using it to combine carbon dioxide and water to produce glucose (sugar) and oxygen. This glucose is then used as a source of energy to fuel the plant's growth and development. Therefore, sunlight is essential for plants to produce their own food through photosynthesis.

  • 13. 

    Almost all living things depend on the process of _____________________ to supply them with the energy they need

    Correct Answer
    photosynthesis
    Explanation
    Almost all living things depend on the process of photosynthesis to supply them with the energy they need. Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. The glucose produced during photosynthesis is used by plants and other organisms as a source of energy. Without photosynthesis, living things would not have access to this essential energy source, making it a crucial process for sustaining life on Earth.

    The two products of photosynthesis are _______________ and  ____________

    Correct Answer
    sugar, oxygen
    Explanation
    Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (sugar) and oxygen. Glucose is a form of sugar that plants use as a source of energy, while oxygen is released into the atmosphere as a byproduct. Therefore, the correct answer is sugar and oxygen.

    Rate this question:

  • 17. 

    The ______________ powers the process of photosynthesis

    Correct Answer
    sunlight
    Explanation
    Sunlight is the correct answer because it is the primary source of energy for the process of photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Sunlight provides the necessary energy for the chemical reactions to occur in the chloroplasts of plant cells, allowing them to produce food and release oxygen as a byproduct. Without sunlight, photosynthesis cannot take place, and plants would not be able to survive.

    Rate this question:

  • 18. 

    Phototropism means _______________________.

    Correct Answer
    Growth from sunlight or Light Growth
    Explanation
    Phototropism refers to the growth or movement of an organism in response to light. It is a natural phenomenon observed in plants, where they tend to grow towards a light source. This is due to the plant hormone called auxin, which accumulates on the shaded side of the plant and causes elongation of cells, resulting in the bending or curvature towards the light. Therefore, the given answer, "Growth from sunlight or Light Growth," accurately describes the concept of phototropism.

    Rate this question:

  • 19. 

    Roots grow downward due to _________________ and this is  called ______________.

    Correct Answer
    gravity, geotropism
    Explanation
    Roots grow downward due to gravity, which is the force that pulls objects towards the center of the Earth. This downward growth is known as geotropism, a plant's response to gravity. Geotropism allows roots to anchor the plant in the soil and helps them access water and nutrients more effectively. This is why roots generally grow in a downward direction, towards the source of gravity.

    Rate this question:

  • 20. 

    The male part of the flower is called the ______________ and the female part is called the ______________.

    Correct Answer
    stamen, pistil or carpel
    Explanation
    The male part of the flower is called the stamen, which consists of the filament and anther. The filament holds up the anther, which produces pollen. The female part of the flower is called the pistil or carpel, which consists of the stigma, style, and ovary. The stigma is the sticky top part that receives pollen, the style is the long tube connecting the stigma to the ovary, and the ovary contains the ovules which will develop into seeds after fertilization.

    Pollination can occur by _________.

    • A.

      Wind

    • B.

      Water

    • C.

      Bees

    • D.

      Wind, water and bees

    Correct Answer
    D. Wind, water and bees
    Explanation
    Pollination can occur through various means, including wind, water, and bees. Wind pollination, also known as anemophily, is common in plants that produce lightweight pollen grains that can be carried by air currents. Water pollination, or hydrophily, is seen in aquatic plants where pollen is released into the water and transported to female reproductive structures. Bees and other insects play a crucial role in pollination, known as entomophily, as they transfer pollen from the male parts of flowers to the female parts while foraging for nectar. Therefore, pollination can occur through wind, water, and the assistance of bees.

    Asexual reproduction requires two parents.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Asexual reproduction actually only requires one parent, not two. In asexual reproduction, an organism can produce offspring that are genetically identical to itself without the need for fertilization or the involvement of another organism. This can occur through various methods such as binary fission, budding, or fragmentation. Therefore, the statement that asexual reproduction requires two parents is incorrect.

    Rate this question:

  • 25. 

    Sexual reproduction requires two parents.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Sexual reproduction is a process where offspring are produced by the fusion of gametes from two parents. In this type of reproduction, genetic material from both parents combines, leading to genetic diversity in the offspring. This is in contrast to asexual reproduction, where only one parent is involved. Therefore, the statement that sexual reproduction requires two parents is true.
