Osmosis is the movement of water molecules across a semi-permeable membrane from a higher to a lower concentration.
Diffusion is the movement of molecules from a region of high solute concentration to a region of low solute concentration.
Endocytosis is the process involving the bulk transport of materials into the cell through membranes. It occurs by the infolding or extension of cell surface membrane to form a vesicle or vacuole. Endocytosis occurs by an infolding or extension of the cell surface membrane to form a vesicle. It is of two types, pinocytosis (cell drinking) and phagocytosis (cell eating). Endocytosis occurs through pseudopodia in amoeba.
When cell is placed in a hypertonic solution water moves out, first from cytoplasm and then from vacuole. Cell membrane shrinks away from the cell wall. This is known as plasmolysis.
Nucleoli is the plural of nucleolus. Nucleolus (nucleoli) are spherical structures that ar present in the nucleoplasm. It is the site for active ribosomal RNA synthesis.
Membrane biogenesis is a process in which living cell membrane is formed from the proteins and lipids synthesised within the cells.
