starch
Plants capture energy from sunlight by means of photosynthesis. Using the green pigment in their leaves called chlorophyll, which makes sugar. They store the sugar primarily as starch. Storage in the form of fat / oil is common too, especially in seeds. Animals mostly store excess sugar in body fat, and plants usually make fruit with excess sugar (as long as they have enough water).
unused carbohydrates in an animal are stored as fat and as starch in a plant.
What is the difference in which in animals and plants store energy?
Plants store carbohydrates as sugars and starches...cellulose is also a complex structural sugar. Animals store glycogen (a type of complexed sugar) in the liver and muscles for fast energy and convert excess carbohydrate to fat.
The body uses glucose as energy. Excess glucose is stored as fat (in animals) and as starch (in plants).
Animals store excess glucose in their liver as a large compound called glycogen. Plants store extra glucose in their starch.
It saves it by stirring it in the leaf.
Liver as glycogen
Animals Store their excess energy in the form of fat's.
starch
The nitrates in nitrogenous waste reduce the oxygen carrying capabilities of the haemoglobin in the blood of animals. Since plants do not have haemoglobin they can absorb it to help them make proteins.
All plants store oil such as olive oil in their seeds. The excess energy that is available is used by plants to make glycerol and fatty acids.
