Function cell does in the body dictate the change and adaptation done by cell structure called Division of Labor which occurs in all living organisms. In plant cells, the cell membrane lies inside the cell wall. (ii) Presence of large central vacuole in plant cell. For example, in textile industry they are woven or attached to the garment and made of fabric, plastic, PVC or leather.Whatever form they assume they perform an important function in every sphere of use. Some of the cell organelles that can be observed under the light microscope include the cell wall, cell membrane, cytoplasm, nucleus, vacuole and chloroplasts. Animal cell under the microscope.
