(c) Explain the development of endosperm in coconut.

Answer 1

Answer:

How to draw this diagram in brainly

Answer 2

Embryo sac & development of endosperm

Explanation:

a) Diagram of embryo sac with labeling.

b) The nucleus of the megaspore divides mitotically to form two nuclei, that move on the opposite poles and forms 2 nucleate embryo sac

c)The development of endosperm in coconut takes place by the following steps:

1.The nucleus of the primary endosperm gets divided bby free nuclear division.

2.The nucleus first divides into 2 and so on till 128 nuclei are formed.

3.By the process of cytokinesis (the process of physical cell division into daughter cells) it finally converts into cellular endosperm.

• Function of endosperm: It provides nutrition to the growing embryo.
