ORGANELLE LOCATION DESCRIPTION FUNCTION cell wall plant, fungi and bacteria but *outer layer *support (grow tall) not animal *rigid, strong, stiff *protection *made of cellulose *allows H2O, O2, CO2 to pass into and out of cell cell membrane both plant/animal *plant - inside cell wall *support All cells *animal - outer layer; cholesterol *protection *selectively permeable *controls movement of materials in/out of cell *barrier between cell and its environment *maintains homeostasis Nucleus both plant/animal *large, oval generally *controls cell activities nucleus is absent in . *key organelle which has the genetic material and is prokaryotic cells involved in multiplication of cell, growth and maintenance of cell. nucleolus All cells except prokaryotes * Make ribosomes, contains building blocks or mRNA, *Found inside cell’s nucleus tRNA, rRNA * may have more than one *disappears during cell division nuclear membrane both plant/animal *surrounds nucleus *Controls movement of materials in/out of nucleus *selectively permeable Centrioles Animal cells *paired structures near the nucleus *stparate chromosome pairs during mitosis *made of cylinder of microtubule pairs cytoplasm both plant/animal *clear, thick, jellylike material *supports /protects cell organelles All cells (sytosol) * organelles found inside cell membrane *contains cytoskelon fibers endoplasmic both plant/animal *network of tubes or membranes *carries materials through cell reticulum (E.R.) Smooth No ribosomes Rough Attached ribosome Synthesis of fats/lipids Ribosomes synthesis proteins for export ribosome both plant/animal *small bodies free or attached to E.R. *synthesizes proteins *made of rRNA and protein Mitochondria both plant/animal *bean-shaped *breaks down sugar molecules into energy *inner membranes *site of aerobic cellular respiration Double membrane outer smooth inner folded into cristae Golgi/golgi bodies / both plant/animal except These are the vacuoles or sac like * to modify and package proteins for export golgi apparatus Prokaryotes structures. They occupy a considerable *have cis and trans face amount of cytoplasm. *stacks of flattened sacs vacuole plant - few/large *fluid-filled sacs * Vacuoles are pouches in the cell that store materials such animal - small as water, salts, proteins, and carbohydrates, waste products and toxic waste.. *store food, water, waste (plants need to store large amounts of food) Vesicles A lot of small bubble sacs in These are small-sized sac like *These help in storage and release of substances as required animals, large sac in the structures. They are of different types by the cell. For example lysosomes help in cell digestion middle of plant cells lysosomes, peroxisomes. when cell dies. Vacuoles function is to store water. lysosome plant - uncommon *small, round, with a membrane *breaks down larger food molecules into smaller molecules animal - common *digests old cell parts chloroplast plant, not animal *green, oval usually containing *uses energy from sun to make food for the plant chlorophyll (green pigment) (photosynthesis) Cilia Animal cells and protozoa Have a 9-2 arrangement of Movement of cell microtubules *short but numerous flagellum Bacteria cells and protozoan *Have a 9-2 arrangement of movement Sex cells microtubules *long but few in number Micro-tubules = All cells *micro-tubules provide structural * the cell has a fixed structure and does not collapse cytoskeleton strength. * form the cyto-skeleton * These are filamentous extensions *moves organelles within the cell in cytoplasm. http://www.biologyjunction.com/cell_functions.htm .
