Answer;

-Sugar

Starch and glycogen molecules are a means for a plant or animal cell to store sugar in order to help maintain homeostasis.

Explanation;

-Sugars are the major sources of energy for organisms, both plants and animals through the process of cellular respiration.

-In plants simple sugars which are the products of photosynthesis are stored in the form of starch, which act as food reserve and is used when necessary.

-In animals glucose is stored in the liver in the form of glycogen. When the sugar levels are high, glucose is converted to glycogen for storage, and when glucose levels are low or when the body has exhausted the available glucose, glycogen is broken down to glucose.
