Nucleus Brain of the cell Controls the cells
Nucleus “Brain of the cell” Controls the cell’s processes Passes on genetic material
Nuclei in cells
Cell Wall “Cell Wall” Keeps invaders out and nutrients in Found in plants, fungi, bacteria; not in animal cells Stiff, allows plants to grow upward Made of cellulose (think stringy part of celery)
Electron micrograph of a cell wall
Cell Membrane “Cell’s skin” Phospholipid bilayer Lets food, water, nutrients in; keeps poisons out In plants, just inside cell wall In animals, the outer covering of the cell
Cell Membrane
Mitochondria (pl. ) “powerhouse of the cell” Breaks down sugar for energy (the energy-rich molecule is called ATP) NNN (no note needed) You received your mitochondria from your mom!
Mitochondrial structure
Ribosome “Manufacturer of the cell” Builds proteins (the major purpose of the cell) Found on ER and cytoplasm
Ribosomes
Endoplasmic Reticulum (ER) “Highway of the cell” - connects to nucleus - transports proteins and other products
Endoplasmic Reticulum
Lysosome “DIGESTER” Filled with enzymes that break down food Digested molecules are passed on to the mitochondria Kill invading bacteria Common in animal cells, rare in plants
Lysosomes
Vacuole “Cell’s storehouse” Store water, food, other needs of the cell Larger in plant cells
Vacuole
Chloroplasts “Solar power plant” Found in plant cells Contains chlorophyll Site of photosynthesis
Chloroplast
Animal Cell
