Answer 2

Answer:

1. Diffusion: It is the movement of a substance from an area of high concentration to an area of low concentration.Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.

2. Osmosis: Movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.

3. Cell: Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions.

4. Endocytosis: Endocytosis is an invagination of the cell surface to form an intracellular membrane-bounded vesicle containing extracellular fluid67; exocytosis may be considered the opposite process—that is, fusion of a plasma membrane–bounded vesicle to the cell surface, followed by release of its contents.
