* Plants: The stored form of carbohydrate in plants is starch. Starch is a complex carbohydrate made up of long chains of glucose molecules. It's found in various parts of the plant, including roots, stems, and seeds. When plants need energy, they break down starch into glucose, which can then be used for cellular processes.

* Animals: The stored form of carbohydrate in animals is glycogen. Glycogen is also a complex carbohydrate composed of glucose molecules, but it's more branched and compact than starch. It's primarily stored in the liver and muscles. When animals require energy, glycogen is broken down into glucose for use.
