Physically, starch appears as a white, odourless and tasteless powder. It is insoluble in both water and alcohol. It is the most common form of energy storage in plants. In plants, starch is also stored in storage organs like roots (cassava plant), tubers (potato), stems (sago plant) and seeds (wheat, rice and corn).

3.2: Carbohydrates

Starch is the stored form of sugars in plants and is made up of a mixture of amylose and amylopectin (both polymers of glucose). Plants are able to synthesize glucose, and the excess glucose, beyond the plant''s immediate energy needs, is stored as starch in different plant parts, including roots and seeds.

Describe and explain two features of starch that make it a good storage

One feature is its compact shape. Starch molecules consists of two components: Amylose and Amylopectin. Amylose is the straight chained part and amylopectin is the branch chained part. Both these structures enable the starch molecule to coil into a compact shape so that it takes the least possible space and is ideal for storage.
