Aleurone layer helps in
1 storage of food in endosperm.
2 protection of embryo.
3 utilization of stored food.
4 All of the above.
Explanation:
The major part of the grain is occupied by a large endosperm which is rich in starch. The endosperm has one to three layered peripheral protein layer called aleurone layer which separates the embryo with endosperm. The aleurone layer helps in utilisation of stored food.

Assertion : Seeds fail to germinate at very low and high temperature. Reason : Seeds sown down deep into the soil fail to germinate.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Statements are incorrect.
Explanation:
Extremely high and low temperatures cause denaturation of cellular proteins and damage the seeds thereby, preventing seed germination.

In the mature bean, gram and pea seed the food material is stored in____
1 Radicle
2 Endosperm
3 Cotyledon
4 Both 2 and 3
Explanation:
In plants such as bean, gram and pea, the cotyledons are often fleshy and full of reserve food materials and the endosperm is not present in mature seeds and such seeds are called nonendospermous.
The major part of the grain is occupied by a large endosperm which is rich in starch. The endosperm has one to three layered peripheral protein layer called aleurone layer which separates the embryo with endosperm. The aleurone layer helps in utilisation of stored food.
