Plant Reproduction and Germination Questions

Multiple choice

The future shoot present in a seed is termed as

  1. radicle

  2. plumule

  3. cotyledon

  4. embryo
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The plumule is the embryonic shoot that develops into the stem and leaves of the plant. Radicle becomes the root, cotyledon stores food, and embryo is the entire immature plant inside the seed.

Multiple choice

The process of development of a seed from an embryo is called

  1. pollination

  2. germination

  3. cleavage

  4. fertilization
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Germination is the process by which a seed develops into a new plant. The embryo within the seed resumes growth under favorable conditions, using the stored food in the seed. Pollination is the transfer of pollen, cleavage refers to cell division in early embryos, and fertilization is the fusion of gametes.

Multiple choice

Two seed leaves are called ______.

  1. monocotyledon

  2. dicotyledon

  3. spores

  4. rhizoid
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dicotyledons (dicots) are plants with two seed leaves (cotyledons) in their embryos. This distinguishes them from monocotyledons (monocots) which have only one seed leaf. Common examples include beans, peas, and most trees.

Multiple choice

How should the seeds be treated before sowing?

  1. They should be properly dried.

  2. They should be properly moistened.

  3. They should be germinated in vitro.

  4. They should be soaked in water for three days.

B Correct answer
Explanation

Seeds should be properly moistened before sowing.

Multiple choice

The Starch cannot move from cell to cell: how does it accumulate in the potato tubers?

  1. Starch is mobilised from leaves to tubers through phloem.

  2. Sugar is synthesised in potato tubers.

  3. It is translocated in the form of sugar.

  4. Some starch from soil might enter the tubers.

  5. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This option is correct. It is translocated in the form of sugar,  which on accumulating in tubers are enzymatically converted into starch.

Multiple choice

Which of the following statements about a seed is not true?

  1. It is the mature ovule after fertilization.

  2. It contains a living plant called an embryo.

  3. It contains cotyledons that protect the growing embryo.

  4. Embryo inside the seed remains dormant in unfavourable conditions.

  5. It contains a small amount of food to nourish the small plant.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Seed cover protects the embryo and cotyledons. It provides the necessary food energy until roots and true leaves are formed.

Multiple choice

Which of the following is not true about dicot seeds?

  1. Cotyledons are thick and fleshy.

  2. Plumule is small and plumule leaves are rolled.

  3. Endosperm is absent.

  4. Hilum and micropyle are clearly visible.

  5. Embryo is large.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In dicot seeds, plumule is large and its leaves are folded.
