   	c.	Excess acetyl-CoA will be used to synthesize fatty acids for storage in adipose (fat) tissue
   	d.	Excess acetyl-CoA will be used to synthesize new amino acids and proteins
   	e.	All of the above

Answer 1

1. Leaves are covered in a waxy cuticle and stomata,which is absent from roots is the one important difference between the anatomy of roots and the anatomy of leaves.

Leaves dermal tissue is covered by waxy cuticle.It prevents evaporative water loss.

Both leaves and roots are having ground tissue.

Leaves,stems,roots,flowers,fruits and seeds are having epidermal tissue.

All plant cells have a cell wall.So leaf cells also have cell wall.

Roots,leaves,stems are having vascular tissue.

So option ''A''is the correct answer.
