Question 6

State whether the following statements are True or False.

  1. Some seeds have no cotyledons.
  2. Warmth is necessary for the germination of seeds.
  3. All seeds have two cotyledons.
  4. Oxygen is necessary for the germination of seeds.
Answer
  1. False
    Reason — Seeds always have cotyledons. Seeds are of two types — monocotyledons having a single cotyledon and dicotyledons having two cotyledons.
  2. True
    Reason — Warmth or a suitable temperature is necessary for germination of seeds because enzymes are inactive at low temperatures and get destroyed at higher temperatures.
  3. False
    Reason — Seeds are of two types — monocotyledons having a single cotyledon and dicotyledons having two cotyledons.
  4. True
    Reason — Oxygen is required to oxidize the stored food and release energy required for the growth of the embryo.
