|
Cell Wall |
A rigid layer of polysaccharide laying on the outside of a plasma membrane. |
|
|
Chromatin |
is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells |
|
|
Nucleolus |
a small dense spherical structure in the nucleus of a cell during interphase. |
|
|
Ribosome |
a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins. |
|
|
Cytoplasm |
the material or protoplasm within a living cell, excluding the nucleus. |
|
|
Lysosome |
an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane. |
|
|
Endoplasmic reticulum |
a network of membranous tubules within the cytoplasm of a eukaryotic cell |
|
|
Golgi apparatus |
a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport. |
|
|
Vacuole |
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid. |
|
|
Chloroplast |
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place. |
|
|
Mitochondria |
an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae |
|
|
Cytoskeleton |
a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.Feedback |
|
|
Cell |
Basic unit of life |
|
|
Cell theory |
All organisms are composed of one or more cells |
|
|
Electron microscope |
a microscope with high magnification and resolution, employing electron beams in place of light and using electron lenses |
|
|
Prokaryotes |
Membrane bound structure and are therefore called prokaryotes |
|
|
Eukaryotes |
Membrane bound structure and are therefore called eukaryotes |
|
|
Organelle |
Each organelle has a specific function for cell survival |
|
|
Plasma membrane |
A microscopic membrane made of lipids and proteins |
