1688374CellA membrane bound structure that is the basic unit of life
1688375Cell MembraneThe lipid bilayer that forms the outer boundary of the cell
1688376Cell TheoryThis says that all living things are made of cells, that cells are the basic unit of structure and function and that cells only come from other cells.
1688377Cell wallA rigid structure that surrounds the cells of plants and most bacteria
1688378ChloroplastA plastid containing chlorophyll, the site of photosynthesis
1688379CytoplasmThe region of the cell between the cell membrane and the nucleus
1688380CytoskeletonA network of long protein strands in the cytosol that helps support the cell
1688381EukaryoteA cell that contains a nucleus and membrane bound organelles
1688382Golgi apparatusA system of membranes that modifies and packages proteins for export by the cell
1688383LysosomesAn organelle containing digestive enzymes,
1688384Mitochondriapowerhouse of the cell, produces energy (ATP) from oxygen and sugar(Cellular respiration)
1688385Nuclear envelopeA double membrane that surrounds the nucleus in the cell
1688386NucleolusThe organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus
1688387NucleusThe organelle that contains the DNA and controls the processes of the cell
1688388OrganelleOne of several bodies with a specialized function that is suspended in the cytosol of the cell

1688391prokaryoteA unicellular organism that lacks a nucleus and membrane bound organelles
1688392RibosomeAn organelle that functions in the synthesis of proteins
1688393tissuea group of similar cells that carry out a similar function
1688394Vacuolestores water and nutrients for the cell; very large in plant cells
1688395vesicleA membrane bound sac that contains materials involved in transport of the cell.
322862802Endoplasmic Reticuluman internal membrane system in which components of cell membrane and some proteins are constructed
