Question:
Why vascular tissue is considered a distinctive feature responsible for the survival of plants in terrestrial plants?
Answer:
Fossils of plants show that vascular tissue appears 400 million years ago. It is believed that aquatic plants moved to terrestrial environment and adaptations like vascular tissue, protected seeds, true roots formation etc. helped in their survival.
- Vascular tissues transport water and minerals throughout a plant. because of this adaptation, water absorbed by roots is able to reach to different parts of the plant. Thus water balance is maintained properly inside plant body. Similarly, food prepared by leaves by photosynthesis is transported to all parts of the plants.
- Vascular tissue also provides structural support to the plant. Vascular tissues form a sort of skeleton and provides support to root, stem and leaves. It also enables plant to grow upright i.e. become taller.
