|
Nucleus
|
Group of cell bodies of neurons in the central nervous system
|
|
|
Nucleolus
|
a conspicuous, rounded body within the nucleus of a cell
|
|
|
Ribosome
|
a tiny, somewhat mitten-shaped organelle occurring in great numbers in the cell cytoplasm either freely, in small clusters, or attached to the outer surfaces of endoplasmic reticula, and functioning as the site of protein manufacture
|
|
|
Rough endoplasmic reticulum
|
a network of tubular membranes within the cytoplasm of the cell studded with ribosomes
|
|
|
Smooth endoplasmic reticulum
|
a network of tubular membranes within the cytoplasm of the cell with a smooth surface
|
|
|
Nuclear envelope
|
the double membrane surrounding the nucleus within a cell
|
|
|
Nuclear pore
|
any of the numerous perforations in a nuclear membrane which allow materials to flow in and out
|
|
|
Golgi apparatus
|
an organelle, consisting of layers of flattened sacs, that takes up and processes secretory and synthetic products from the endoplasmic reticulum and then either releases the finished products into various parts of the cell cytoplasm or secretes them to the outside of the cell.
|
|
|
Cytoplasm
|
the cell substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles.
|
|
|
Mitochondria
|
an organelle in the cytoplasm of cells that functions in energy production.
|
|
|
Plasma/cell membrane
|
the semipermeable membrane enclosing the cytoplasm of a cell
|
|
|
Cell wall
|
the definite boundary or wall that is part of the outer structure of certain cells, as a plant cell
|
|
|
Vacuole
|
a membrane-bound cavity within a cell, often containing a watery liquid or secretion
|
|
|
Chloroplasts
|
A chlorophyll-containing plastid found in algal and green plant cells
|
|
|
Lysosome
|
a cell organelle containing enzymes that digest particles and that disintegrate the cell after its death
|
|
|
Microtubules/microfilaments
|
Any of the proteinaceous cylindrical hollow structures that are distributed throughout the cytoplasm of eukaryotic cells, providing structural support and assisting in cellular locomotion and transport
|
|
|
Chromatin
|
the readily stainable substance of a cell nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division
|
|
|
Centriole
|
small, cylindrical cell organelle, seen near the nucleus in the cytoplasm of most eukaryotic cells, that divides in perpendicular fashion during mitosis, the new pair of centrioles moving ahead of the spindle to opposite poles of the cell as the cell divides
