what is a function of glycogen in plants?
159361
Glycogen is the analogue of starch, a glucose polymer that functions as energy storage in plants. It has a structure similar to amylopectin (a component of starch), but is more extensively branched and compact than starch.

Glycogen (animal starch) is a polysaccharide that serves the same energy storage function in animals that starch serves in plants. Dietary carbohydrates not needed for immediate energy are converted by the body to glycogen for long term storage (principally in muscle and liver cells).

The function of parenchyma cells is in the storage of foods, in gaseous exchange, and in photosynthesis, while collenchyma cells provide mechanical support and elasticity to the plant, the sclerenchyma cells provides mechanical support to the plant. It also supports transportation of water and nutrients to the plants.

Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by α glycosidic bonds. Glycogen and starch are highly branched, as the diagram at right shows.

The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses.

A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters. The composition of cell walls varies between species and may depend on cell type and developmental stage. The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses and pectin.

> Glucose has three main fates: immediate use to produce ATP molecules (available energy for work), storage for later ATP production, or for use in building other molecules. Storage as starch (in Plants) or glycogen (in animals).

As nouns the difference between glycogen and glycerol is that glycogen is (carbohydrate) a polysaccharide that is the main form of carbohydrate storage in animals; converted to glucose as needed while glycerol is glycerol.

Glycogen is the energy-storing carbohydrate that is found mainly in animals and fungi whereas Starch is the energy storage carbohydrate found in plant cells. Glycogen is made up of the single-molecule whereas starch comprises two molecules amylose and amylopectin.

Answers. Starch is the storage form of glucose (energy) in plants, while cellulose is a structural component of the plant cell wall. Glycogen is the storage form of glucose (energy) in animals.

The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy.

Leaves enable photosynthesis to occur. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.

The process of cellular respiration allows plants to break down glucose into ATP. The ATP provides the energy they need to carry out various functions. Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.

The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.
