NEET BIOLOGY

Detailed explanation-1: -Cells of plant tissue have cell wall. Cells of animal tissue do not have cell wall. Some tissues are living and some are dead. All tissues are living.

Detailed explanation-2: -The primary difference between plant tissue and animal tissue is that plant tissues have cell walls made of cellulose while animal tissues have a membrane made of protein. Ans. Cellulose plays an important role in the process of photosynthesis, which allows plants to store sugar molecules in their cells.

Detailed explanation-3: -Plants are stationary or fixed – they don’t move. So, they need tissues that are supportive, which provides them with structural strength. Since dead cells can provide mechanical strength better than live cells, and need less maintenance most of the plant cells are dead.

Detailed explanation-4: -Most plant tissues are dead, since dead cells can provide mechanical strength as easily as live ones, and need less maintenance. These dead cells are limited to certain regions that are responsible for providing mechanical strength or other protective functions.

Detailed explanation-5: -The amount of dead tissue is more in plants than animals. Many essential functions in plants are attributed to dead tissues. Dead tissue provides support and mechanical strength to plants, e.g., sclerenchyma. Apart from this, the main conducting tissue in plants, xylem is mostly composed of dead cells.
