MS is a chronic illness involving the central nervous system. The immune system attacks myelin, which is the protective layer around nerve fibers. This causes inflammation and scar tissue, or lesions. This can make it hard for your brain to send signals to the rest of your body.
The parts of the plant cell are as follows: Plants cell constitute of membrane bound nucleus and many cellular structures. These organelles carry out funct ions that are necessary for the proper functioning and survival of the cell. The cell orga nelles of the plant are enclosed by a cell wall and cell membrane.
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.
