Which of the following best describe the jobs roots do?
- A.
Support plants and allow leaves to reach sunlight
- B.
Anchor plants and take in water and nutrients
- C.
Make food for the plant and take in air
- D.
Absord light energy and make sugar and oxygen
Correct Answer
B. Anchor plants and take in water and nutrientsExplanation
The roots of a plant serve as an anchor, holding the plant in place and providing stability. They also absorb water and nutrients from the soil, which are essential for the plant's growth and survival. Therefore, the statement "Anchor plants and take in water and nutrients" best describes the function of roots.Rate this question:

Which of the following is NOT a job done by stems?
- A.
Support the plant
- B.
Enable leaves to reach sunlight
- C.
Carry water and nutrients to the leaves
- D.
Make food for the plant
Correct Answer
D. Make food for the plantExplanation
Stems do not make food for the plant. The process of making food, known as photosynthesis, is primarily carried out by the leaves of a plant. The stems of a plant have various functions such as supporting the plant, enabling leaves to reach sunlight, and transporting water and nutrients to the leaves. However, they do not play a direct role in the production of food through photosynthesis.Rate this question:

What is the main job of plant leaves?
- A.
Make food for the plant
- B.
Keep the plant from drying out
- C.
Carry water and nutrients from soil
- D.
Cool the plant
Correct Answer
A. Make food for the plantExplanation
Plant leaves have a vital role in photosynthesis, the process by which plants convert sunlight into energy. They contain chlorophyll, a pigment that absorbs sunlight, and other necessary components for photosynthesis. Through this process, leaves produce glucose, which is the plant's food source. Therefore, the main job of plant leaves is to make food for the plant.Rate this question:

The small openings in the underside of a leaf are called _____________________.
- A.
Epidermis
- B.
Xylem
- C.
Stomata
- D.
Phloem
Correct Answer
C. StomataExplanation
Stomata are the small openings found on the underside of a leaf that allow for gas exchange. They are responsible for the exchange of carbon dioxide and oxygen during photosynthesis and respiration. The opening and closing of stomata are regulated by guard cells, which control the movement of gases and water vapor in and out of the leaf. The epidermis is the outermost layer of the leaf, while xylem and phloem are vascular tissues responsible for transporting water, nutrients, and sugars within the plant.Rate this question:

The loss of water through plant leaves is __________________________.
- A.
Transpiration
- B.
Photosynthesis
- C.
Chlorophyll
- D.
Epidermis
Correct Answer
A. TranspirationExplanation
Transpiration is the process by which water is lost from plant leaves through small openings called stomata. This loss of water is essential for the plant's survival as it helps in the transportation of nutrients and minerals from the roots to other parts of the plant. It also helps in regulating the temperature of the plant and maintaining its overall health. Therefore, transpiration is the correct answer as it accurately describes the loss of water through plant leaves.Rate this question:

The outter layer of cells on a leaf is the _______________________.
- A.
Stomata
- B.
Epidermis
- C.
Stem
- D.
Chloroplast
Correct Answer
B. EpidermisExplanation
The outer layer of cells on a leaf is called the epidermis. The epidermis acts as a protective barrier for the leaf, preventing water loss and protecting it from external factors such as pathogens and UV radiation. It also contains specialized structures called stomata, which regulate the exchange of gases (such as oxygen and carbon dioxide) between the leaf and the environment. The epidermis is crucial for maintaining the overall health and functioning of the leaf.Rate this question:

The process by which plants make food is ___________________________.
- A.
Transpiration
- B.
Growing
- C.
Photosynthesis
- D.
Respiration
Correct Answer
C. PhotosynthesisExplanation
Photosynthesis is the correct answer because it is the process through which plants convert sunlight, water, and carbon dioxide into glucose (food) and oxygen. During photosynthesis, plants use chlorophyll in their leaves to capture sunlight energy and convert it into chemical energy, which is stored in the form of glucose. This process is essential for the survival of plants and is the primary way in which they produce their own food.Rate this question:

Three things needed by plants for the production of food are:
- A.
Water, oxygen, and sunlight
- B.
Water, carbon dioxide, and fertilizer
- C.
Water, oxygen, and sugar
- D.
Water, carbon dioxide, and sunlight
Correct Answer
D. Water, carbon dioxide, and sunlightExplanation
Plants require water, carbon dioxide, and sunlight for the production of food through the process of photosynthesis. Water is essential for transporting nutrients and maintaining cell structure. Carbon dioxide is necessary for plants to convert into glucose during photosynthesis. Sunlight provides the energy needed to drive the chemical reactions involved in the process. Oxygen is a byproduct of photosynthesis, not a requirement for food production. Sugar is produced as a result of photosynthesis, but it is not one of the necessary components for the process itself.Rate this question:

The green pigment in chloroplasts that enable a plant to absorb light energy to make food is _______________________.
- A.
Carbon dioxide
- B.
Chlorophyll
- C.
Chloroplast
- D.
Color
Correct Answer
B. ChlorophyllExplanation
Chlorophyll is the correct answer because it is the green pigment found in chloroplasts that enables plants to absorb light energy for photosynthesis. It plays a crucial role in capturing sunlight and converting it into chemical energy, which is used to produce food for the plant.Rate this question:

Plants take in ________________________ from the air.
- A.
Carbon dioxide
- B.
Chlorophyll
- C.
Oxygen
- D.
Energy
Correct Answer
A. Carbon dioxideExplanation
Plants take in carbon dioxide from the air as part of the process of photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. The carbon dioxide is absorbed through small openings in the leaves called stomata. It is then used by the plant to create energy-rich molecules that fuel its growth and development. Therefore, carbon dioxide is an essential component for plants to carry out their metabolic processes and produce the necessary energy for survival.Rate this question:

_________________________ is released by plants as a byproduct of photosynthesis.
- A.
Energy
- B.
Carbon dioxide
- C.
Oxygen
- D.
Chlorophyll
Correct Answer
C. OxygenExplanation
During photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Oxygen is released as a byproduct into the atmosphere. This process is crucial for the survival of plants as well as other organisms that rely on oxygen for respiration. Therefore, oxygen is the correct answer as it is the byproduct released by plants during photosynthesis.Rate this question:

Plants are called ___________________________ because they make their own food.
- A.
Photosynthesis
- B.
Consumers
- C.
Producers
- D.
Chlorophyll
Correct Answer
C. ProducersExplanation
Plants are called "producers" because they have the ability to produce their own food through the process of photosynthesis. They use chlorophyll, a pigment found in their cells, to capture sunlight energy and convert it into chemical energy. This energy is then used to convert carbon dioxide and water into glucose, which serves as their food source. Unlike consumers, which rely on consuming other organisms for their energy needs, plants are able to sustain themselves by producing their own food.Rate this question:

Animals that eat other plants or animals are called _______________________.
- A.
Photosynthesis
- B.
Producers
- C.
Carnivores
- D.
Consumers
Correct Answer
D. ConsumersExplanation
Consumers are animals that eat other plants or animals for their energy and nutrients. Unlike producers, such as plants, consumers cannot produce their own food through processes like photosynthesis. Carnivores are a specific type of consumer that primarily eat other animals, while consumers can also include herbivores that eat plants and omnivores that eat both plants and animals. Therefore, the correct answer is consumers.Rate this question:
