By Diffusion and Osmosis.
Diffusion is literally a "process of scattering" (diffus). The scattering process of diffusion arises from the fact that all particles are constantly moving in random directions. During diffusion, particles move by chance from a region where their concentration is high, to a region where their concentration is low.
osmosis -is the net movement of water molecules across a semipermeable membrane from a region of a higher concentration to a region of lower concentration...
Transport protein
The plasma membrane helps to maintain homeostassi within the cell by allowing substances to move in and out of the cell the plasma membrane is used to maintain homeostasis within the cell by allowing substances to move in and out of the cell
The Cell Membrane is usually attributed with controling which substances can move in and out of the cell.
No, phagocytosis is a process where a cell engulfs and internalizes solid particles or other cells. It is not used to move substances out of a cell but rather to bring them into the cell for processes like digestion or immune response.
The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
Cell membrane controls which substances can move in and out of a cell. It is the dynamic boundary of cell

Projections that allow the cell to move or to move substances along the surface of the cell are called cilia and flagella. Flagella is a single long hair that allows the cell to swim. Cilia are several projections used for movement across the cell surface.
