Question

what is cell sap. give its composition

Answer 1

CELL SAP------------->. The solution that fills the vacuoles of plant cells is called cell sap......... Cell sap consists of water and various substances that are often in the form of a colloidal suspension. On the average, cell sap has twice the viscosity of water. In dormant seeds and spores the cell sap dehydrates, hydrating again upon germination. Young cells have less cell sap than older ones. The composition of cell sap is specific to families and even to species, depending also on growth conditions, the age of the plant, and the age of the individual cells. Cell sap contains the carbohydrates glucose, fructose, sucrose (grapes, apples, pears, sugar beets), and inulin (dahlia, Jerusalem artichoke), pectins (citrus, currants, apples), and glycosides (hesperidin, amygdalin); tannins; a number of amino acids (leucine, tyrosine); alkaloids (nicotine, anabasine, caffeine); organic acids (oxalic, citric, malic); and inorganic acids. Calcium oxalate crystals are found as inclusions. The cell sap of some marine algae contains iodine and bromine.

Answer 2

Answer:

Definition: Cell sap is the liquid which is present inside a central vacuole of plant cell.

Composition: Sugars, glucose, amino acids, waste substances and mineral salts.

Explanation:

Definition: Cell sap is the liquid which is present inside the large central vacuole of the plant cell. It helps in the storage of materials. It provides mechanical support to the plants, especially in non-woody plants. It plays a vital role in plant cell osmosis. It also provides buoyancy. Cell sap usually has twice the viscosity of water. Older cells have more cell sap than younger ones.

Composition: Cell sap consists of glycosides, glucose, fructose, sucrose (grapes, apples, etc.), inulin (dahlia), carbohydrates, tannins, waste products, mineral salts, amino acids, alkaloids, organic acids and inorganic acids. The cell sap of marine algae consists of iodine and bromine.
