Question

In animals, food is stored in the form of………………………
A. Glycogen
B. Starch
C. Glucose
D. Sugar

Answer 1

Hint:Plants can prepare their food material by using the solar energy provided by the sun which is a natural source of energy. The process by which plants prepare their food material by using the chlorophyll and sunlight is called photosynthesis. Animals depend on plants for food material.

Complete answer:
In animals, food is stored in the form of glycogen. Plants can prepare their food material by the process of photosynthesis and so they are called producers or autotrophs. The process by which plants prepare food material by using sunlight and chlorophyll and convert carbon dioxide into carbohydrate and release molecular oxygen is called photosynthesis. Animals cannot prepare their own food material and they depend on the nutrition from plants. They are called heterotrophs because they depend on other organisms for their food. Plants are called consumers.

Animals store food in the form of glycogen whereas plants store food material in the form of starch.
Digestive processes in both plants and animals convert starch to glucose which is an ultimate source of energy. Starch is one of the major and essential components of human diet. Starch is a white, odorless, tasteless carbohydrate that is important in both plants and animal cells.

Therefore, the correct answer is option (A) Glycogen.

Note:The main difference between plant cell and animal cell is that a plant cell contains a large single vacuole that is used for storage and maintenance of the shape of the cell whereas animal cells have many small vacuoles. Plant cells have a cell wall and cell membrane whereas the cell of a plant is surrounded only by cell membrane.
