PPT-The Plasma Membrane TSW understand the physical structure and functions of the cell membrane

What is the plasma membrane A flexible boundary between the cell and its environment which maintains HOMEOSTASIS within the cell Remember that HOMEOSTASIS is a state of balanceequilibrium within the cell.

Flexible, sturdy barrier of the cell.. Kumar . Saha. Dept. of Zoology. Rajshahi. University. Physiology of Plasma membrane. :. The plasma membrane acts as a thin barrier which separates the intracellular fluid or the cytoplasm from extracellular fluid in which the cell live.. The plasma membrane is a SELECTIVELY PERMEABLE membrane that allows nutrients and wastes to enter and exit the cell. Homeostasis: maintaining balance in the cell. The Plasma Membrane. Selective Permeability – allows some molecules to pass through and keeps others out. Inclusion Body. Nucleoid. Mesosome. Cell Wall. Nucleus. Mitochondrion. Rough Endoplasmic Reticulum.

True cells occurring in plants and animals . Though they have different shape size and physiology but all cells are typically composed of plasma membrane cytoplasm and its organelles i.e. mitochondria, endoplasmic reticulum .
