Plant Reproduction and Germination Questions

Multiple choice

Which of the following plants produces seeds but not flowers?

  1. Maize

  2. Mint

  3. Peepal

  4. Pinus
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

 Pinus is a gymnospermic plant. Ovulves of pinus are uncovered, which lie on the megasporophyll, hence this plant does not have flowers. However, it produces seeds like other three plants mentioned, all of the other three are angiosperms.

Multiple choice

In gymnosperms, the seeds are naked because they lack

  1. integument

  2. nucellus

  3. pericarp

  4. perianth
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

After fertilization, the ovary develops into fruit and ovary wall forms the fruit wall (pericarp). But gymnosperms have naked seeds because in gymnosperms, ovary (pericarp) is absent.

Multiple choice

Take some dry seeds of moong or chana. Put a small quantity of seeds in a container filled with water and leave this aside for a day. Next day, drain the water completely and leave the seeds in the vessel. Wrap them with a piece of wet cloth and set aside. The following day small white structure may have grown out of the seeds. If so, the seeds have

  1. Grown

  2. Died

  3. Sprouted

  4. Dried

C Correct answer
Explanation

Germinated seeds are known as sprouts.

Multiple choice

Which of the following statements is/are correct?

a. The part of a baby plant in seed which develops into shoot is called radicle. b. The part of a baby plant in seed which develops into root is called plumule. c. The part of seed which contains food for the baby plant is called cotyledon.

  1. a, b and c

  2. a and b

  3. only a

  4. only b

  5. only c
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is the correct answer as this statement is correct. The part of seed which contains food for the baby plant is called cotyledon.

Multiple choice

Which of the following seeds can be sprouted and eaten?

  1. Mustard seeds

  2. Sunflower seeds

  3. Moong seeds

  4. Maize seeds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Yes, it is the correct answer. When the seeds develop tiny roots after the germination, then these tiny roots are known as sprouts. These sprouts contain vitamins and minerals and make the seeds more nutritious. Moong seeds are widely used to make sprouts.

Multiple choice

What type of the seeds should not be used for sowing?

  1. Good quality seeds

  2. Hollow and lighter seeds

  3. High yielding seeds

  4. Clean and healthy seeds
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hollow and lighter seeds are typically damaged or immature and will not germinate properly, so they should be discarded before sowing.

Multiple choice

Where do we store seeds?

  1. In silos

  2. In granaries

  3. In cold stores

  4. Both (1) and (2)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Correct option is (4).

Multiple choice

Cotyledons are called

  1. seeds

  2. leaves

  3. seed leaves

  4. seed flowers
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cotyledons are called seed leaves.

Multiple choice

Nucellus forms

  1. seed coat

  2. perisperm

  3. seed

  4. raphe

  5. -
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In angiosperms, it is the central portion of the ovule in which the embryo sac develops. In some cases of apomixis (production of seeds without fertilisation), cells of the nucellus develop into an embryo. Perisperm is a mass of nutritive material that is outside the embryo sac.

Multiple choice

Poor quality seeds are

  1. hollow

  2. light

  3. big

  4. both (1) and (2)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Poor quality seeds are hollow and light. Good quality seeds are clean and healthy.
