Summary Introduction

To write:

The vocabulary term for the given definition.

Introduction:

The diversity of plants and its 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 have lack of specialized transport tissue while the vascular plants have specialized transport tissue.

Explanation of Solution

In some of the sporophytic generation of seedless vascular plants it has been observed that they adapt strobilus that means compact cluster of spore bearing structures. The spore formed in the strobilus is often carried by the wind and in favorable condition they form the gametophyte.

Conclusion

The spore bearing structures that form a compact cluster is termed as strobilus found in many seedless vascular plants.
