Answer:
Plant cell
Explanation:
Cell wall: cell wall is only found in plant cell . it is made up of cellulose. it's function is to give shape to the cell and protect the delicate inner parts of the cell. this cell is fully permeable. it means it will allow all substance to pass in. cell membrane is made up of protein and lipids. it's function is to control what comes in and out of the cell. this membrane is selectively permeable. it means it allows some substance to pass in and others don't. cytoplasm is large sac like structure. most chemical process occur here. chromoplast are the green pigments.
cell wall is only found in plant cell . it is absent In animal cell . the neucleus in the plant cell contain a pigments haemoglobin, which contain genetic information to the cell .
