Found in plants, algae & bacteria (not animals).Folded inner membrane for increased surface area Ĭhloroplast Photosynthesis uses solar energy to synthesise energy rich food molecules Ĭell wall Tough, rigid outer structure for support.Mitochondria Respiration – breaks down food releasing energy to convert ADP to ATP Enclosed in nuclear envelope with pores.Nucleus Controls cell activities and contains genetic code Membrane-bound to prevent digestion of cell contents.Store digestive enzymes (digest food molecules, worn-out organelles, engulfed bacteria etc).Plant cells usually have one very large vacuole, animal cells have a number of small vacuoles.Controls turgidity (how full or limp the cell is).raw materials used in synthesis of proteins.Cell sap - concentrated solution of sugars, salt and suspended proteins.mucus in goblet cells Allows transport of materials.add carbohydrate component to glycoproteins.

Golgi Bodies / apparatus Series of flattened hollow discs Packages proteins & lipids in pinched-off vesicles:

Large surface area for ribosome attachment.

Rough ER – has ribosomes for protein synthesis.

Smooth ER - synthesis of lipids, including steroids, and calcium storage in muscles.

connects with membrane system within cell Įndoplasmic reticulum Tube-like network from nucleus to membrane.

Cell Organelles Cytoplasm – matrix of the cell Membrane system – includes endoplasmic reticulum & golgi bodies Organelles – self-contained, membrane-bound structures such as nucleus, mitochondria, chloroplasts Vesicles – membrane-bound bubbles of liquid, including vacuoles, lysosomes, secretory and transport vesiclesĬell (plasma) membrane Surrounds cytoplasm and organelles and controls entry/exit of all substances (semi-permeable)
