bacteria
the main sugar that provides energy for cells
this is supportive structure is found in plant cells but not animal cells
cell wall
eukaryotic organism, usually single-celled, cannot be classified as a fungus, plant, or animal
protist
the maintenance of a stable internal environment despite changing external conditions
homeostasis
Have a cell wall, make their own food, and are multicellular
plants
captures energy from sunlight
chlorophyll
single celled organisms that lack a nucleus and membrane-bound organelles
prokaryote
a eukaryotic organism that feeds by absorbing its food
