Cell membrane, permeability, transport

No

Yes

Diffusion, osmosis, then facilitated diffusion.

Endocytosis, exocytosis, sodium-potassium pump.

The degree to which a cell membrane allows substances to pass through.

A membrane that allows only specific substances to pass through.

A membrane that doesnt allow anything to pass through.

The fluid mosaic model

A process in which molecules are entering the cell.

A process in which molecules are exiting the cell.

Robert E Hooke

It describes how an extracellular solution can change the volume of a cell by affecting osmosis.

It describes the total solute dissolved in a solution (expressed as osmoles of solute per liter of water)

It has a greater number of water molecules relative to the number of solute particles.

It has fewer water molecules with respect to solute particles .

Extracellular fluid has lower osmolarity than the fluid inside the cell, and water enters the cell (cell will burst)

Extracellular fluid has a higher osmolarity than the cells fluid. (cell will shrink due to lack of water)

Extracellular fluid has the same osmolarity as the cell (no net movement of water in and out) (cell retains shape)

Channel and carrier

The most common form of endocytosis. Pinocytosis takes dissolved molecules into a vesicle.

A form of endocytosis where some integral proteins take molecules in receptors.

Molecules move from areas of high to low concentration. it doesnt require the assistance of membrane proteins.
