Summary Introduction

Introduction: The angiosperms are known as flowering plants and they also produce seeds. Bryophyta is a phylum which is divided into three divisions, namely the hornworts, liverworts, and the mosses. Pteridophytes are also divided into three divisions and they are the horsetails, ferns, and the lycophytes.

Answer to Problem 1TY

Correct answer: The most ancient and simplest phylum of modern land plants is the liverworts, hornworts, or mosses. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Liverworts, hornworts and mosses do not possess any roots, and they do not have vascular tissues as well. These land plants are very small ancient plants. They are usually found in the moist environment as they lack vascular tissues. They are considered as one of the earliest evolving plants.

Option c. is given as, “the liverworts, mosses, or hornworts”.

Liverworts, hornworts and mosses are the most ancient phylum, and the simplest of the modern land plants. Hence, option c. is correct.

Reasons for incorrect answer:

Option a. is given as, “the pteridophytes”.

Pteridophytes possess vascular tissues xylem and phloem and they are taller than the bryophytes. Therefore, they cannot be considered as simplest plant. Hence, option a. is incorrect.

Option b. is given as, “the cycads”.

The cycads belong to gymnosperms and it is not the simplest modern land plants. Hence, option b. is incorrect.

Option d. is given as, “the angiosperms”.

Angiosperm is the most recently evolved plant and it has a highly developed phylum. They are also known as flowering plant. Hence, option d. is incorrect.

Option e. is given as, “none of the above”.

In all the given option, liverworts, mosses, or hornworts are the simplest and ancient plants. Hence, option e. is incorrect.

Hence, the options a., b., d., and e. are incorrect.

Conclusion

Liverworts, mosses, or hornworts are the simplest and ancient group of modern plants.

The Sentinel Cell: Nature’s Answer to Cancer?
Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?
