Cell
The smallest unit that can preform all life processes cells
cell membrane
phospholipid layer that covers a cells surface
organelle
small bodies in a cells cytoplasm that are specialized to perform a specific function
nucleus
a membrane-bound organelle that contains the cells DNA and that has a role in processes such as growth metabolism, and reproduction
cell wall
a rigid structure that surrounds the cell membrane and provides support to the cell
ribosome
cell organelle composed of RNA and protein the site of protein synthesis
endoplasmic reticulum
a system of membranes that is found in a cell’s cytoplasm and that assists in the reproduction,processeing, and in the transport of proteins and in the production of lipids
mitochondrion
cell organelle that is surrounded by two membranes and that is the site of cellular respiration
golgi complex
cell organelle that helps make and package materials to be transported out of the cell
