Pteridophytes are the first vascular plants in plant kingdom. Give some reasons for the dominance of vascular plants over non-vascular plants on the earth.

Explanation

### Step-by-Step Solution:

1. **Definition of Vascular Plants**: Vascular plants, such as Pteridophytes, are characterized by the presence of specialized tissues known as xylem and phloem. These tissues are crucial for the transport of water, nutrients, and food throughout the plant.

2. **Presence of True Roots, Stems, and Leaves**: Vascular plants have true roots, stems, and leaves, which allow them to grow larger and more complex than non-vascular plants. This structural complexity enables them to occupy a variety of ecological niches.

3. **Efficient Transportation System**: The xylem transports water and minerals from the roots to the rest of the plant, while the phloem distributes the food produced through photosynthesis. This efficient transportation system allows vascular plants to thrive in diverse environments and to grow taller and larger than non-vascular plants.
