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
