Two main functions of polysaccharides in living things are:
1. structural components
2. energy storage.
Those polysaccharides that are not easily broken down are used as structural components. Some of them are cellulose in plants and chitin in insects and crustacean.
On the other hand, starch and glycogen are easily broken down, so they serve as energy storage. <span>When energy is needed immediately, they break down to glucose and great amount of energy is released, </span>
The term is the known process that is called "nuclear fission"
Answer:
The surface area of the cell increases to volume ratio
Explanation:
As a cell grows, the surface area of the cell increases to volume ratio. When cell division occurs, the surface area is distributed and each daughter cell have less surface area but with the passage of time, the surface area increases. The main function of mitosis is to increase the population of the cell, the cell must be divided into two daughter cells in the process of mitosis. Tumors occurs when the process of mitosis is uncontrollable. One observation that is found interesting while looking at the onion root tip cells is the multiplication of the cells by the process of mitosis.
