Sample Questions

1multiple correct

Which of the following are essential conditions for seed germination?

Show answer

Water, Suitable temperature, Oxygen

The three essential conditions for seed germination are water (for swelling and enzyme action), suitable temperature (25-35°C), and oxygen (for respiration). Sunlight is not needed initially as seeds have stored food.

2multiple choice

The scar on the seed coat marking the point of attachment to the ovary is called:

Show answer

Hilum

Hilum is the scar on the seed coat where the seed was attached to the ovary wall. Micropyle is a small opening, testa is the outer seed coat, and tegmen is the inner seed coat.

3true false

In epigeal germination, the cotyledons are pushed above the ground.

Show answer

True

In epigeal germination, the hypocotyl elongates and pushes the cotyledons above the ground. This happens in bean and castor seeds. In hypogeal germination, cotyledons remain underground.

4multiple choice

Which part of the maize grain stores food for the embryo?

Show answer

Endosperm

In maize grain, the large endosperm stores food (mainly starch) for the embryo. The scutellum (cotyledon) absorbs food from the endosperm and transfers it to the embryo.
