Organelles Prokaryotes vs. Eukaryotes
Prokaryotes • Cells have no nucleus • Information for heredity is contained within the cytoplasm. • First cells to evolve • Ex: Bacteria
Eukaryotes • Have nucleus • Information for heredity is contained within the nucleus • Cells evolve from prokaryotes • EX: Animals, protists, fungi, & plants
Organelles • Tiny membrane-bound structures that perform special functions inside the cell.
Cell Wall • Only found in plants, fungi, & bacterial cells • Strong, rigid, & stiff. • Provides support & protection for the cell.
Cell Membrane • Membrane that protects and supports the cell. • Allows movement of nutrients in and out of the cell. • Included in ALL cells.
Nucleus • Found in both plant and animal cells. • Large, oval shape • Centrally located (center) • Controls the activities of the cell.
Cytoplasm • Both plant and animal cells. • Clear, thick, jelly-like substance • Supports and protects the organelles.
Golgi apparatus • Plant and animal cells • Looks like flattened stack of pancakes • Packages proteins made by the cell
Ribosomes • Plant and animal cells • Can be attached to the endoplasmic rectiulum (ER) or free floating • Produces proteins
Endoplasmic reticulum • Plants and animal cells • Network of tubes • Transports materials throughout the cell. • Rough & smooth (types)
mitochondria • Plant and animal cells • Looks like a jellybean • Breaks down sugars to release useable energy.
vacuoles • Plant and animal cells • Fluid filled sacs • Store food, water, & waste
lysosomes • Only in animal cells • Small & Round • Breaks down large food molecules into smaller ones. • Digests old cell parts
chloroplasts • Plant cells ONLY • Oval • Green from cholorophyll • Uses energy from the sun to make food
