Question:
Why do plants have more dead tissues as compared to animals?
Answer:
Most of the plant tissues are dead since dead cells can provide mechanical strength as easily as live ones, and need less maintenance. Also, plants have sedentary life i.e. they are stationary. Therefore plant tissues require less amount of energy.
