19Photosynthesis takes place in the (leaves / root) of a plant. (Sunlight / Water) supplies the energy a plant needs to make sugar.Carbon dioxide enters the plant through the (xylem / stomata).The cell parts of green plants where photosynthesis takes place are (mesophyll / chloroplasts).A plant gives off (oxygen / carbon dioxide) as a byproduct during photosynthesis.Water is taken into a plant through the (roots / veins).An organism that gets food by eating other organisms is (an autotroph / a heterotroph).
20Cellular RespirationA chemical reaction that takes place in the mitochondriaThis reaction releases energy for the cell to use
