Nucleus
what is a phospholipid layer that covers a cells surface.
Cell membrane

organelles
what is an organism that consists of a single cell that does not have a nucleus.
prokaryote
what is an organism made up of cells that have a nucleus enclosed by a membrane
eukaryote
a rigid structure that surrounds the cell membrane and provides support to the cell
Cell wall
a cell organelle composed of RNA and protein
ribosome
a system of membranes that is found in a cells cytoplasm and that assists in the production, processing, and transport of protein and in the production of lipids
endoplasmic reticulum
in eukaryotic cells the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
mitochondrion
a cell organelle that helps make and package materials to be transported out of the cell
Golgi complex
a cell organelle that contains digestive enzymes
lysosome
a group of similar cells that perform a common function of the body
tissue
a collection of tissues that carry out a specialized
organ
