Why do plant cells have chloroplasts and cells walls and not animals cells?
Well, chloroplast is a green chemical that is excreted by the plant cell, in turn making most plant parts green and causes photosnythesis. Plant cells have a cell wall because since they dont have any bones, that wall [once the vacuole, the water/food container, is full] rises up, becomes rigid, and holds the plant up erect. We have a skeleton to keep us standing or sitting, etc. so we dont need extra support from our cells.
