Cytoplasm is the cytoplasmic membrane surrounded by all the translucent, gelatinous, granular material in addition to the nuclear region of the general term. Mainly for material transportation, biochemical reaction place, to provide raw materials for the synthesis of substances, is the structural basis of the cell. 1. Material transportation function, including the absorption of nutrients, raw material intake and metabolic waste discharge and product secretion. 2. The cytoplasm is the main place for metabolism, the vast majority of chemical reactions are carried out in the cytoplasm, glycolysis, nucleic acids, fatty acids and amino acids metabolism of the various phases, need to rely on the cytoplasm in a relatively free state of the enzyme to complete. Provide a place for various biochemical reactions in the cell to ensure normal life activities. 3. To provide raw materials for synthesizing substances for the cell nucleus and various organelles. Cytoplasm is the cytoplasmic membrane surrounded by all the translucent, gelatinous, granular material in addition to the nuclear region of the general term. The main components are ribosomes, storage, a variety of enzymes and intermediate metabolites, a variety of nutrients and macromolecules, such as monomers, a few bacteria and cysts, carboxylase, bubbles or spore crystals. 4. is the structural basis of the cell, providing the required environment to ensure normal cellular life activities.
