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).
The starch cells found in plants with the fat cells found in animals are similar in the way they function as an energy reserve.
Starch is a polysaccharide (a carbohydrate that is made up of a long chain of monosaccharides) that functions as an energy reserve in most plants.
Starch cells is the most abundant reserve carbohydrate in plants and is found in leaves, different types of stems and roots in which it is used as a source of energy during periods of dormancy, stress or restart of the increase.
On the other hand, animals store excess energy in the form of fat, which is an organic substance whose components are fatty acids combined with glycerin.
Adipocytes are cells specialized in forming and storing fat, a gram of anhydrous fat stores around six times the metabolic energy of a gram of hydrated glycogen, allowing the maximum amount of energy to be stored.
- Starch supplies the energy and carbon skeletons necessary for plant metabolism during periods of darkness, when photosynthesis is inactive.
- Fat cells serve as an energy reserve and as protection for the viscera, each animal species stores fat reserves according to their needs.
- Subcutaneous fat deposits also serve as thermal insulators to conserve body heat, and as a protective pad against bumps and bruises.
Therefore, we can conclude that the starch cells found in plants with the fat cells found in animals are similar in the way they function as an energy reserve.
