Plasmodesmata have a diameter of 50–60 nm in diameter. They have three layers i.e. plasma membrane, cytoplasmic sleeve, and the desmotubules. these layers can thicken the cell wall up to about 90nm. Plasma membrane –it is a continuous extension on the plasmalemma that is made up of ph...
A cell membrane is a thin flexible lipid-based layer situated at the far exterior of cells. The cell membrane is the barrier that separates a cell from its outside environment or from other cells. Its composition makes it semipermeable. It is also called the plasma membrane. Besides this bas...
38、lateral diffusion of membrane lipids can demonstrated experimentally by a technique called Fluorescence Recovery After Photobleaching (FRAP)(光脱色荧光恢复技术光脱色荧光恢复技术 ). Figure. Diagram of an epithelial cell showing how a plasma membrane protein is restricted to a particular domain of the...
Another diagram of a generalised animal cell is shown below:The cell is made-up of 'little organs' or organelles. The cell consists of a cell surface membrane (plasma membrane or plasmalemma) which acts as the cell's 'skin' and as the cell border the membrane determines what substances ...
The primary plasma membrane function is to protect, contain and provide unit structure to cells. It is composed of thinly structured phospholipid bilayer and protein molecules and it found as a major component of every biological cell, while serving to divide the inner environment of the cell from...
A history of cell membrane research was recently published by Lombard. [7] The cell membrane (also called plasma membrane) is a thin, semi-permeable membrane that surrounds the cytoplasm of a cell and separates it from the extracellular space. Cells were first described by Robert Hooke in the...

3.3.8Antibody-secreting Cells (Plasma Cells) Antibody-forming cells are generally considered to be terminally differentiated ‘end’ cells incapable of further division, with a lifespan of a few days at the most (Nossal and Ada, 1971). The antibody-secreting B cell is often called a ‘plasma...
