IMPORTANT TERMS:
· Agranal Chloroplast: Chloroplasts having thylakoids that do not form grana as in algae.
· Active Transport: A method in which a cell transports material by expending energy.
· Antiport:Counter transport of two solutes across a membrane in opposite direction.
· Bioplast: A term originally used for a mitochondrion by Altman (1890).
· Cell Biology: The study of organization and functioning of cell.
· Cytology:The study of cell with the help of light microscope.
· Cyclosis:Constant movement of cytoplasm around the vacuole/vacuoles.
· Co-transport: Transport of a molecule and an ion together across a membrane by a single carrier protein.
· Differentially Permeable: A selectively permeable membrane that allows some particles to pass through and prevent others at the same time.
· Ergastoplasm:A term originally used for granular endoplasmic reticulum by Granier (1897).
· Ergasome: Another term for a polyribosome.
· Electrochemical: The difference of electrical charges and concentration of the ions present on two sides of a membrane.
· Golgi-ER-Lysosome (GERL): A region of Golgi maturating face, thought to be involved in the production of lysosomes and/ or pre secretory granules.
· MTOCs:Microtubule organizing centre.
· Nucleolar Organizer: Chromosomal region that contains the genes for ribosomes RNAs and induces formation of nucleolus.
· Osmotic Potential: It is the capacity of a solution to take in water from the other side of a semi- permeable membrane.

· Totipotency:The ability of a somatic cell to form a complete organism.
· Turgidity:A state of a plant cell when the cells protoplast exerts pressure on the cell wall due to endosmosis.
