Summary Introduction

To write:

The characteristics because of which non-vascular plants have a lack of transportation tissue.

Introduction:

The diversity of plants and their classification depends on adaptation. The plants are classified into twelve divisions. These twelve divisions of plants are divided into two groups; the non-vascular plants and the vascular plants. The non-vascular plants lack specialized transport tissue while the vascular plants have specialized transport tissue.

Explanation of Solution

The non-vascular plants are evolved along with algae. They lack vascular tissue; therefore do not allow the materials to move within so easily. They grow in shady and damp places so that they can absorb the water and nutrients from the environment directly. They do not have true leaves therefore the photosynthesis process is carried out by a layer of cells. The water and other substances are transported through by osmosis and diffusion process due to the lack of true vascular tissue.

Conclusion

The non-vascular plants do not have true vascular cells, therefore they undergo osmosis and diffusion process for the transportation of water and other substance. They absorb water directly from the atmosphere.
