Describe the differences between the sporophyte and gametophyte generations of seedless tracheophyte plants and be sure to discuss structures and ploidy.

Answer and Explanation:

Tracheophyte plants, also known as vascular plants, are those that possess a supportive tissue that can also conduct fluids -The Xileme- and another tissue that conducts nutritious elements produced by photosynthesis -The Phloem-. These plants have a root (basically underground), a stem (aerial), and leaves. All of them together form the corm. And the corm counts with these vascular tissues to which we referred before.  

There are different types of Tracheophyte plants, some of them produce seeds to reproduce and disperse -Spermatophyta-  and some others reproduce and disperse by spores -Pteridophyta-. This last seedless group corresponds to ferns and other similar plants.

Pteridophytes characterizes for having a sporophyte that has stems with leaves and a root. It also has primitive xylem composed by tracheids and phloem, both of them formed by vascular bundles located in a central cylinder.

Spores are its dispersion units and are responsible for colonizing new areas. They also constitute the resistance units under extremely unfavorable conditions.  

Their life cycle is composed of the asexual phase (sporophytic phase) and the sexual phase (gametophytic).  

the correct answer is:

a population changes in response to a change in the environment.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
