Question

How are starch cells in plants and fat cells in animals similar and different? I'll give a medal to the first correct answer.

Answer 1

Firstly, there is no such thing as 'starch cells' in plants. Starch in plants is stored as starch grains/granules in the chloroplasts. To answer your question in a highly simplified manner:
Both starch in plants and fat cells in animals serve as a store of energy. However, fats in animals are generally stored in fat cells (forming the adipose tissue) while starch in plants is stored in the chloroplasts. Also, fats and starch are 2 totally different compounds with different chemical compositions and structures (I won't elaborate on the types of fats and starches in this thread though).
