Cell Organelle Ribosomes Tiny dots Cell Wall Thick wall separating cells What it’s made of! COMPOSITION Membrane (thank you Captain Obvious) Protein and nucleic acid Cellulose and/or chitin (carbs) Vacuole Swimming pool Membrane Stores water & nutrients Rough endoplasmic reticulum Squiggly lines surrounding nucleus, covered with dots Like rough ER, but no dots Membrane Internal storage and transport of proteins Membrane Internal transport of lipids Hormones made here! Looks like a Membrane stack of pancakes Packages proteins for external transport Breaks down food and bacterial invaders Makes Lysosomes Organelle Cell membrane Smooth endoplasmic reticulum Golgi apparatus Lysosomes How to recognize it! APPEARANCE Thin line between cells Featureless spots, Membrane + bigger than enzymes ribosomes What it does in the cell. FUNCTION Transport of substances in/out of cell Creates proteins Structural support SPECIAL NOTES Will be looked at in many units! Millions in every cell Helps with Turgor Pressure Only found in plants, fungi and some protists and bacteria Turgor Pressure: When full of water, it pushes against cell wall to keep plant upright Only in animal cells
