Firstly, plant cells have a cell wall that surrounds the cell membrane, whereas animal cells do not. ... These additional organe
lles allow plants to form an upright structure without the need for a skeleton (cell wall and central vacuole), and also allow them to produce their own food through photosynthesis (chloroplasts).
This question appears incomplete. However, one of the main differences (in organelles) between plants and animal cells is the absence of cell wall and chloroplast in animal cells while both organelles are present in plant cells. The cell wall is outside of the cell membrane. The cell wall provides rigidity and support to the plant cell while the chloroplast is the cellular "machinery" for photosynthesis. The chloroplast contains the green pigment called chlorophyll which provides green plants with there colour and assist the plants in absorbing/capturing of sunlight/energy for the purpose of photosynthesis (self production of food by green plants).
