Question

difference between perisperm and endosperm​

Answer 1

Hint: In some seeds, such as black pepper and beet remnants of nucellus are also persistent. This residual persistent nucellus is perisperm while the part of a seed that acts as a food store for the developing plant embryo, containing starch with protein and other nutrients are endosperm.

Complete answer:

Perisperm

1.It represents persistent remains of nucellus (of ovule) to the seed.

2.It is a part that belongs to seed.

3.It is usually dry.

4.It is the diploid food storage tissue originating from nucellus.

5It is diploid in nature.

Example: Black pepper

Endosperm

1.It develops from the primary endosperm nucleus.

2 It contains reserve food materials.

3.It is usually in fluid form.

4.It is the triploid food storage tissue originating from triple fusion.

5.It is triploid in nature.

Example: Wheat.
