Question

the following tissue does not act as nutritive tissue
a. nucleus
b. endothecium
c. tapetum
d. endosperm ​

Answer 1

Answer:

Option C. tapetum I think

Answer 2

Endothecium does not act as nutritive tissue.

• The nucellus is the protective cover of the embryo sac and it is also a food reserve that's why it is also a nutritive tissue.
• Endothecium is a protective layer around the pollen sac which helps in the dehiscence of the anther.
• Tapetum is the innermost layer and completely surrounds the sporogenous tissue and it nourishes the developing pollen grains.
• The endosperm plays an important role in supporting embryonic growth by supplying nutrients, protecting the embryo and controlling embryo growth by acting as a mechanical barrier during seed development and germination.
• Hence, endothecium is the correct option.
