This contrasts with the cell walls of fungi (which are made of chitin), and of bacteria, which are made of peptidoglycan. Cell walls perform many essential functions: they provide shape to form the tissue and organs of the plant, and play an important role in intercellular communication and plant-microbe interactions.
This membrane provides shape to the cells of plants and animals. Cell wall is an additional covering over the cell membrane in plant cells. It gives shape and rigidity to these cells. Cell Structure and Function Each organ in the system performs different functions such as digestion, assimilation and absorption.Similarly, different organs of a plant perform specific/specialized functions. Plant cells contain chloroplasts which are used for photosynthesis. â¢ Plant cells have a large vacuole (it's like a fluid sack), compared to an animal cell. â¢ Animal cells are 'blobby', but cells in plants are more structured due to the cell wall, and form a lattice like structure which helps with rigid ness.
