plasmas function

Maintains osmotic pressure and viscosity of the blood Helps in transport of various substances like the hormones, enzymes, etc. Acts as a protein reservoir Helps in clotting of blood Helps in regulating body temperatur..

Plasma Membrane - The plasma membrane or cell membrane surrounds the cell contents in all types of cells. It is a multipurpose covering composed of phospholipids and proteins. fig. 16.4 - Cell Membrane Apart from the plasma membrane, an eukaryotic cell also shows intra..

It is present in both plant and animal cells. It is living, elastic and made of proteins and lipids (fats). Its function is to provide a mechanical barrier for the protection of the inner cell contents and to regulate the movement of molecules in and out of the cel..

It transports oxygen to all the parts of the body. It collects carbon dioxide from the cells and transports it to the respiratory organs. It distributes the digested food to all the regions of the body. It collects metabolic waste products from the cells and transports them to the excret..

Vitamins are the important food factors required in diet. Different vitamins are involved in different biochemical functions. They are required in very low concentration, the daily requirement of any vitamin for any individual is extremely smell. The daily dose of any vitamin is not a fix..

These are invaginations formed by the plasma membrane. They are spherical or elongated structures which bring about a functional compartmentalisation of the cell. They have significant roles in cell division and replication. They are more common in Gram positive bacteri..

Every cell, whether it is prokaryotic or eukaryotic, is enclosed in a thin covering called cell membrane . It is also called as plasma membrane or plasma lemma . The cell membrane can only be seen through the electron microscope since its thickness is well below the resolving po..

Question: What is the function of the cell wall? Answer: The cell wall lies outside the plasma membrane and is responsible for providing structural strengths to the plants..

Lymph - It is another type of fluid connective tissue. It is characterized by the absence of RBC. Hence, it has a plasma containing only WBC. Some of the plasma proteins found in blood, are absent in the lymph. Lymph flows only inside definite vessels called lymph vessels or lac..

Plasma membrane: The permeability of the plasma membrane decreases due to the accumulation of calcium in the membrane. Endoplasmic reticulum: In the cytoplasm of old cells, granular ER decreases. In the nerve cells, nissl granules are decreased. Mitochondria: Mitochondri..
