Detailed explanation-1: -The movement of a substance across the cell membrane is known as cell transport. The substance can move either in or out of the cells. There are various molecules that pass through the plasma membrane or the cell membrane.
Detailed explanation-2: -Cells are filled and surrounded by watery fluid. This fluid helps solids move around inside, outside the cell and cross the cell membrane. The cell membrane controls what moves in and out of the cell. Cell membranes only allow some solutes (solids) to move across it.
Detailed explanation-3: -Diffusion is an essential process in cells. They need glucose and oxygen for respiration, which move into them by diffusion. Respiration produces carbon dioxide and water which leave cells by diffusion. (Water actually leaves cells by osmosis, which is the diffusion of water across a membrane.)
Detailed explanation-4: -Plasma membrane controls the flow of substances in and out of cell.
Detailed explanation-5: -Endoplasmic Reticulum is mainly responsible for the transportation of proteins and other carbohydrates to another organelle, which includes lysosomes, Golgi apparatus, plasma membrane, etc.
