Chloroplast - key organelle for photosynthesis (only found in plant cells) Cell wall - extra layer of protection (only found in plant cells) Cell membrane - the part of the cell which separates the cells from the outside environment and protects the cell, as well as regulating what goes in and out of the cell Cilium - motile structure of eukaryotes having a cytoskeleton, the axoneme. Cytoplasm - contents of the main fluid-filled space inside cells. Any chemical reactions also happen in here. Cytoskeleton - protein filaments inside cells Endoplasmic reticulum - major site of membrane protein synthesis Flagellum - motile structure of bacteria, archaea and eukaryotes Golgi apparatus - site of protein glycosylation in the endomembrane system Lipid bilayer - fundamental organizational structure of cell membranes Lysosome - break down cellular waste products and debris into simple compounds (only found in animal cells) Membrane lipid and protein barrier Mitochondrion - major energy-producing organelle by releasing it in the form of ATP Nucleus - holds most of the DNA of eukaryotic cells and controls all cellular activities Organelle - term used for major subcellular structures Ribosome - RNA and protein complex required for protein synthesis in cells Vesicle - small membrane-bounded spheres inside cells |
