    Which substance makes plants green?

    • Vacuole

    • Carbon dioxide

    • Oxygen

    • Chlorophyll

    Correct Answer
    A. Chlorophyll
    Explanation
    Chlorophyll is the pigment responsible for the green color in plants. It is located in the chloroplasts of plant cells and plays a crucial role in photosynthesis. Chlorophyll absorbs sunlight and converts it into chemical energy, which is used to produce glucose and oxygen. Without chlorophyll, plants would not be able to carry out photosynthesis and would not be green.

    Rate this question:

  • 5. 

    In addition to sunlight, what else is required for photosynthesis to take place?

    • Carbon-dioxide and water

    • Sugar and water

    • Salt and sugar

    • Sugar and carbon-dioxide

    Correct Answer
    A. Carbon-dioxide and water
    Explanation
    Photosynthesis is the process by which plants convert sunlight into energy. In addition to sunlight, plants require carbon dioxide and water to carry out this process. Carbon dioxide is absorbed from the atmosphere through tiny pores called stomata in the leaves. Water is absorbed through the roots and transported to the leaves. Inside the chloroplasts of the plant cells, sunlight, carbon dioxide, and water are used to produce glucose (sugar) and oxygen through a series of chemical reactions. Therefore, carbon dioxide and water are essential for photosynthesis to occur.

    • Stigma, Style, Ovary

    Correct Answer
    A. Stigma, Style, Ovary
    Explanation
    The correct answer is Stigma, Style, Ovary. In a plant, the female reproductive system, also known as the pistil, consists of three main parts: the stigma, style, and ovary. The stigma is the sticky structure at the top of the pistil that receives pollen. The style is a long tube-like structure that connects the stigma to the ovary. The ovary is the enlarged base of the pistil that contains the ovules, which eventually develop into seeds after fertilization.

    Rate this question:

  • 7. 

    What is the leaves biggest job?

    • Eat

    • Photosynthesis

    • Direct the plant.

    Correct Answer
    A. Photosynthesis
    Explanation
    Photosynthesis is the correct answer because it is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. This process occurs in the leaves of plants and is essential for their survival as it provides them with the energy they need to grow and carry out other functions. Without photosynthesis, plants would not be able to produce food and oxygen, making it the biggest job of the leaves.

    Rate this question:

  • 8. 

    Which gas is used by plants to make food?

    • Oxygen

    • Carbon dioxide

    • Helium

    • Hydrogen

    Correct Answer
    A. Carbon dioxide
    Explanation
    Plants use carbon dioxide to make food through a process called photosynthesis. During photosynthesis, plants absorb carbon dioxide from the atmosphere and combine it with water and sunlight to produce glucose and oxygen. This glucose serves as the plant's food source, while oxygen is released back into the air as a byproduct. Oxygen is not used by plants to make food but is released during the process. Helium and hydrogen are not involved in photosynthesis and are not used by plants for food production.

    Which of the following factors reduce erosion?   - ProProfs

    Which of the following factors reduce erosion?  

    • Increasing the amount of rainfall.

    • Increasing the slope of land (Bigger hills)

    • Increasing the amount of plants.

    • Increasing the population

    Correct Answer
    A. Increasing the amount of plants.
    Explanation
    Increasing the amount of plants helps to reduce erosion because plants have roots that hold the soil in place, preventing it from being washed away by rainfall or carried away by wind. The roots also help to bind the soil particles together, making it more difficult for them to be eroded. Additionally, the leaves and stems of plants act as a physical barrier, reducing the impact of raindrops on the soil surface and slowing down the flow of water, further reducing erosion.

    Plants with roots, stems, leaves, and flowers reproduce with-

    • Spores.

    • Seeds.

    • Chloroplasts.

    • Cell walls.

    Correct Answer
    A. Seeds.
    Explanation
    Plants with roots, stems, leaves, and flowers reproduce with seeds. Seeds are the reproductive structures of plants that contain an embryo and are capable of developing into a new plant. They are produced through the process of sexual reproduction, where pollen from the male reproductive organ (stamen) fertilizes the female reproductive organ (pistil). The fertilized ovule then develops into a seed, which can be dispersed and germinate under favorable conditions to give rise to a new plant. This method of reproduction is common in angiosperms, which are flowering plants.

    A process through which plants loose water    - ProProfs

    A process through which plants loose water   

    • Dehydration

    • Respiration

    • Transpiration

    • Prespiration

    Correct Answer
    A. Transpiration
    Explanation
    Transpiration is the process through which plants lose water. It occurs mainly through the stomata, small openings on the surface of leaves. During transpiration, water is evaporated from the plant's tissues and exits through the stomata into the atmosphere. This process is crucial for the plant's survival as it helps in nutrient uptake, cooling, and maintaining turgidity. Respiration is the process of breaking down organic compounds to release energy, not related to water loss. Dehydration refers to the loss of water in general, not specific to plants. "Prespiration" is not a valid term and does not relate to the process described.
