Food which is stored in different organs of plants is of various forms. This food material includes starch, glucose, sucrose, reserve cellulose, inulin, glycogen as carbonhydrates. Fats and oils are found in almost all living cells. In oily seed very little of carbohydrates is found. Food is stored as proteins in the from of Aleurone grains which are found abundantly in oily seed. Pluses are rich in proteins.
Large amount of food is stored up in endorsperm and cotyledons of seed. This stored food is used up by embryo for its growth. Food is stored here in insoluble form, it is firstly changed into simpler form which is soluble. This conversion is die to action of certain enzymes
Cereals e.g. rice, maize, wheat, oat, barley etc. are rich in starch. On the cell walls of endosperm reserve cellulose is deposited e.g. date palms, beta-nut-palm. There is a great deposition of oils in seeds of coconut, castor, sunflower, groundnut etc. Soybean has maximum amount of proteins. About 35% proteins are present in soybeans oily seed such as castor seed also contains a high percentage of proteins
Digestion Assimilation:-Protoplasm of cells absorb only food in the soluble forms which is suitable for translocation through the whole body of plant and ultimated assimilation of his food materials by protoplasm of cell..
This process of digestion takes place inside the cells, it is known as intracellular digestion. In carnivorous plants and in parasites the digestion is extra cellular. Protoplasm secretes some of the enzymes which help in conversion of insoluble food-staffs into simpler soluble forms. Enzymes are soluble in water and are protein in nature. These are at first formed as minute granules known as zymogen. This zymogen is then converted into active enzyme e.g. pepsin form pepsinogen and trypsim from trypsinogen. At 70oC Properties of these enzymes are lost.
