Reproductive structures aside, even multicellular protists (ex. Algae) and fungi had only one or two types of cells. Plants and animals show significant differentiation of cell types specialized for particular jobs. 10 cells in plants and 200 in animals (different types of cells) Ground tissue (tissue in the middle: parenchyma generic living cell in the middle (chloroplasts, collenchyma provides support while plant is still growing occur, toxins, photosynthesis etc. ) (not completely rigid ex.
