CH. 3 CELLS

Gives the cell shape, structure and helps it move Made of:  Microfilaments  Intermediate filaments  Microtubules CYTOSKELETON

The “goo” that surrounds the nucleus Keeps everything in place Organelles are suspended in cytoplasm CYTOPLASM

RIBOSOMES

Ribosomes Structure-spheres composed of RNA and protein Function-site of protein synthesis Free ribosomes make proteins that remain inside the cell Attached ribosomes make proteins that become part of the cell or are exported from the cell

THESE ARE FREE RIBOSOMES (IN THE CYTOSOL).

Nucleus

ENDOPLASMIC RETICULUM ROUGH

ENDOPLASMIC RETICULUM SMOOTH

GOLGI APPARATUS Location In the cytoplasm Structure Closely stacked, flattened membrane sacs Function Stores, packages, and transports products inside for use outside Vesicles (a bit of the golgi pinches for transport of stored materials).

VESICLE Small sac in the cell Usually full of liquid

Golgi Apparatus

LYSOSOME (NOT FOUND IN PLANTS)

MITOCHONDRIA (FOUND IN ALL EUKARYOTIC CELLS)

Made of protein Found in animal cells Help pull apart cells in mitosis CENTRIOLE

VACUOLE

CHLOROPLAST.

CELL WALL Location surrounding Plant cells Structure contains polysaccharide cellulose Function Provides structure and support for plant cells

____________ are found only in Plant cells. They take in light energy and store it in carbohydrates during photosynthesis. Note the cell wall and central vacuole in this diagram of a plant cell. They are also found only in plant cells.
