NEET BIOLOGY

Detailed explanation-1: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-2: -The plasma membrane is the border between the interior and exterior of a cell. As such, it controls passage of various molecules-including sugars, amino acids, ions, and water-into and out of the cell.

Detailed explanation-3: -membrane, in biology, the thin layer that forms the outer boundary of a living cell or of an internal cell compartment. The outer boundary is the plasma membrane, and the compartments enclosed by internal membranes are called organelles.

Detailed explanation-4: -Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell.

Detailed explanation-5: -Cell Membrane-The outside boundary of the animal cell, the part next to the cell wall in a plant. In both cells, it controls what enters and exits the cell. It is semi-permeable – lets some things through. Nucleus-The control center of the cell that directs all of the cell activities.
