How a cell works

Cell shapes

The 4 basic shapes of prokaryotes

Coccus (pl. cocci) – spherical
Spirillum (pl. spirilla) – spiral-shaped
Bacillus (pl. bacilli) – pill-shaped
Vibrio – comma-shaped

Eukaryotes

The cytoskeleton gives them their shape: http://etap.org/demo/biology1/instructiontutor_last.html

Animal cells have irregular shapes. Plant cells have regular and generally rectangular shapes.

Organelle

Function

Similar to

Cell membrane –  Protects the cell

–  Controls the movement of substances in and out of the cell

Skin
Cytoplasm Allows organelles and substances to move within the cell Blood
Ribosome Synthesizes proteins, which are involved in virtually every cell function

(e.g. providing support, movement)

Proteins

– almost everything, from bones to muscles

Mitochondrion (pl. …dria) Site for respiration to provide the cell with energy Stomach & small intestines
Nucleus –  Controls all activities within the cell

–  Protects the cell’s genetic information (i.e DNA)

Brain

 

 

 

What did the video compare the cell with? Why?

–> I have no idea what the video is…
