BIOL 1201 Chapter : Photosyth
Document Summary
2 types of plants: multicellular eukaryotes that do photosynthesis, unicellular eukaryotes that do photosynthesis (algae) Both eukaryotic and have an organelle called chloroplast. 2 differences: diff : multicellular: millions on cells w/ in just one leaf; containing several dozen copies of chloroplasts. 2 guard cells: form guard cells: form little mouths called stoma . What type of cell are guard cells? dermal cells turn on different sets of genes. That can be opened or closed is response to enviormetnal parameters: 2 substances: co2 and h2o (required for photosynthesis to make glucose) > a waxy layer coating upper and bottom surface so that water or carbon diox cannot move through. Stoma in the lower surface of the leaf is where : water leaves the leaf co2 enters. Equation: co2 + h2o >>>> c6h12o6+o6(glucose) (>>>>>>> = presence of sunlight) Image of lower surface of the leaf: jig saw shape.
