In biology, the smallest unit that can perform all life processes; cells are covered by a membrane and have DNA and cytoplasm.
Cell
In a eukaryotic cell, a membrane-bound organelle that contains the cells DNA and that has a role in process such as growth metabolism, and reproduction.
Nucleus
A liquid that organelles float in.
Cytoplasm
A phospholipid layer that covers a cells’ surface; acts as a barrier between the inside of a cell and the cells’ environment.
Cell membrane
A rigid structure that surrounds the cell membrane and provides support to the cell.
Cell wall
In eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration.
Mitochondrion
Organelles in plant and algae cells in which photosynthesis takes place.
Chloroplast
Cell organelle that helps make and package materials to be transported out of the cell.
Golgi complex
A system of membranes that is found in a cell’s cytoplasm ans that assists in the production, processing, and transport of proteins and in the production of lipids.
Endoplasmic reticulum
Cell organelle composed of RNA and protein; site of protein synthesis.
Ribosome
A cell organelle that contains digestive enzymes.
Lysosome
The organelle that stores water and other materials.
Vacuole
One of the small bodies in a cell’s cytoplasm that are specialized to perform a specific function.
Organelle
An organism that consists of a single cell that does not have a nucleus.
Prokaryote
An organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals, plants, and fungi, but not archaebacteria or eubacteria.
Eukaryote
