write a short note on a plant cell. 150 to 200 words
Plant cell is an example of eukaryotic cell. It is surrounded by outermost cell wall and made up of cellulose. Cellulose is a complex substance and provides structural strength to plants. Inside the cell wall, there is a selectively permeable membrane known as plasma membrane. The plasma membrane allows or permits the entry and exit of some materials in and out of the cell. It also prevents movement of some other materials. The cell membrane, therefore, is called a selectively permeable membrane. Plant cell also contains membrane bound organelles like nucleus, mitochondria, chloroplast, golgi bodies etc embedded in the cytoplasm. These organelles help plant cell in performing the essential metabolic functions.
