The fundamental unit of life
2) Plasmolysis - Shrinkage or contraction of the protoplasm away from the
wall of a living plant or bacterial cell, caused by loss of water through
osmosis.
3) Cell organelle – A specialized subunit within a cell that has a
specific function, and is usually separately enclosed within its own membrane.
4) Genes - A hereditary unit consisting of a sequence of DNA that
occupies a specific location on a chromosome and determines a particular
characteristic in an organism.
5) Membrane biogenesis – The process of synthesizing the biological
membranes.
6) Plasma membrane – The thin, selectively permeable membrane composed of
lipids and proteins which surrounds an entire cell and regulates the flow of
substances to and from the cell.
7) Cell wall – The rigid, non-living, outer covering of certain cells
(like plant and bacteria), composed mainly of cellulose and providing the cell
with structural support and protection.
8) Cytoplasm - The jellylike material of a cell that is enclosed within
the plasma membrane, except the nucleus and contains the cell organelles.
9) Chloroplasts – The plastids containing chlorophyll which are capable
of carrying out photosynthesis in plants.
