Questions and Answers
  • 1. 

    Why do all seeds not grow into new plants?

  • 2. 

    What is a food web?

  • 3. 

    The baby plant inside the seed is also known as 

    • A.

      Sapling

    • B.

      Seedling

    • C.

      Embryo

    Correct Answer
    B. Seedling
    Explanation
    A seedling refers to the baby plant that emerges from a seed and begins to grow. It is the initial stage of growth for a plant, after the seed has germinated. The term "sapling" typically refers to a young tree that has already grown beyond the seedling stage. "Embryo" refers to the undeveloped or early stage of a plant or animal before it is fully formed. Therefore, the correct answer for the baby plant inside the seed is "seedling."

    It has two cotyledons 

    • A.

      Gram

    • B.

      Wheat

    • C.

      Rice

    Correct Answer
    A. Gram
    Explanation
    Gram is the correct answer because it has two cotyledons. Cotyledons are the embryonic leaves in the seed of a flowering plant. Gram, also known as chickpea, is a legume that belongs to the family Fabaceae. Like other legumes, gram seeds have two cotyledons, which is a characteristic feature of this plant family. Wheat and rice, on the other hand, are monocotyledonous plants, meaning they have only one cotyledon.

    It is not necessary for germination 

    • A.

      Air

    • B.

      Sunlight

    • C.

      Water

    Correct Answer
    A. Air
    Explanation
    Air is necessary for germination because it contains oxygen, which is required for the respiration process in plants. During germination, the seed absorbs oxygen from the air, which is then used to break down stored food and provide energy for growth. Without air, the seed would not be able to respire and germination would not occur.

    The colour of chlorophyll is 

    • A.

      Red

    • B.

      Green

    • C.

      Yellow

    Correct Answer
    B. Green
    Explanation
    Chlorophyll is a pigment found in plants and algae that is responsible for absorbing sunlight during photosynthesis. It is green in color because it absorbs most wavelengths of light in the blue and red regions of the spectrum, reflecting and transmitting green light. This is why plants appear green to our eyes. The green color of chlorophyll allows plants to efficiently capture and utilize light energy for photosynthesis.

    It is not an insectivorous plant 

    • A.

      Pitcher plant

    • B.

      Venus fly trap

    • C.

      Petunia

    Correct Answer
    C. Petunia
    Explanation
    Petunia is the correct answer because it is not an insectivorous plant. Insectivorous plants, such as the pitcher plant and Venus fly trap, have adaptations to capture and digest insects for nutrients. However, petunias are not capable of trapping and consuming insects. They are flowering plants that rely on other means, such as pollination by insects, for reproduction.

  • 8. 

    During photosynthesis the gas released is 

    • A.

      Oxygen

    • B.

      Nitrogen

    • C.

      Carbondioxide

    Correct Answer
    A. Oxygen
    Explanation
    During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. Oxygen is released as a byproduct of this process and is essential for the survival of most living organisms. Therefore, the correct answer is oxygen.

    It is a parasite 

    • A.

      Snake

    • B.

      Lice

    • C.

      Earthworm

    Correct Answer
    B. Lice
    Explanation
    Lice are parasitic insects that infest the hair and feathers of animals, including humans. They feed on blood and can cause itching and irritation. Therefore, the statement "it is a parasite" accurately describes lice, as they rely on a host organism for survival and reproduction. Snakes and earthworms, on the other hand, are not parasites.

    Reproduction through buds occur in 

    • A.

      Sugarcane

    • B.

      Mushroom

    • C.

      Ginger

    Correct Answer
    C. Ginger
    Explanation
    Reproduction through buds occurs in ginger. Ginger plants reproduce asexually through a process called budding. In this process, small buds or offshoots develop on the rhizomes (underground stems) of the ginger plant. These buds eventually grow into new plants, allowing ginger to spread and propagate. This method of reproduction is advantageous for ginger plants as it allows them to rapidly and efficiently produce offspring without the need for pollination or the production of seeds.

    Which of the following is not an omnivorous 

    • A.

      Bear

    • B.

      Horse

    • C.

      Dog

    Correct Answer
    B. Horse
    Explanation
    The horse is not an omnivorous animal. Unlike bears and dogs, horses are herbivores and primarily feed on plant material such as grass and hay. They have a specialized digestive system that is adapted for processing plant matter, and they do not consume meat or other animal products as a regular part of their diet.
