O Protection
O Nutrition
O Reproduction
O Dehiscence​

Answer 1

Answer:

nutrition is the answer

Answer 2

Answer:

Thickening of cellulose fibers in anther helps in "Dehiscence​".

Explanation:

Thickening of cellulose fibers in anther helps in "Dehiscence​".

1) The epidermis, endothecium, middle layer, and tapetum are the four layers that make up an anther in angiosperms.

2) Prior to the anther dehiscence, the "endothecium" forms a fibrous layer. The anther's cells are encased in a fibrous cell wall, as is typical of plant cells, which supports a high internal cell turgor pressure.

3) Cells of the endothecium in an anther develop a "fibrous thickening" from the "inner tangential walls" to the "outer wall." Due to its hygroscopic nature, endothecium facilitates the dissemination of microspores.
