Cheek cells, being animal cells, do not contain a cell wall as onion â¦ cells do becasue cell walls are found only in plant cells for structure and rigidness. Onion cells, unlike most plant cells, do not have chlorplasts becasue it does not need sunlight for photosynthesis as other plants do.
A plant cell differs from an animal cell in having certain distincti â¦ ve structures-cell wall, vacuoles, plasmodesmata and plastids. On the contrary, plant cells lack centrioles and intermediate filaments, which are present in animal cells.f the plant is watered with fresh water, the osmotic potential would cause water to move into the cells of the plant because the concentration of water outside is greater tha â¦ n the concentration of water inside.
