A eukaryote is an organism whose cells contain a nucleus within a membrane. ... In fact, most living things are eukaryotes, made up of cells with distinct nuclei and chromosomes that contain their DNA.
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.
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).
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment consisting of a lipid ...

a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
the material or protoplasm within a living cell, excluding the nucleus.
