Document Summary
Chloroplast, photosynthetic, uses light for energy (chloroplast) and information (uses the eyespot: eyespot can absorb light that looks at light and uses it to figure out where things are so it can move around. What else does this cell need to function: nucleus, chloroplast, rough er, mitochondria, ribosomes, lysosomes, vacuole, channelrhodopsin, membrane. On the branch that lead to plants, but it not a plant (type of green algae), is a protest. Shares similarities with fungi and animals in ways plants do not. Two mating types: plus (+) and minus (-) Humans have a huge amount of junk dna, chlamy doesn"t have as much. Humans are larger, but only have 5,000 more pcg. Cell uses information from light for movement. Phototransduction absorb light: eyespot - flagellum. Plasma membrane is polarized (difference in charges) outside positive, inside negative, cell needs to maintain the state.
