Chapter 31, Problem 1U

The lack of seeds is a characteristic of all

a. lycophytes.

b. conifers.

c. trachcophytcs.

d. gnctophytcs.

Expert Solution & Answer

Summary Introduction

Introduction:

Some plants in the previous time do not have seeds but have vascular tissues and they showed dispersion by wind blowing. The ferns, whisks, horsetails all are seedless and do not have flowers.

Answer to Problem 1U

Correct answer:

The seeds are not present in lycophytes. Therefore, option a. is correct.

Explanation of Solution

Reason for the correct statement:

The lycophytes are the seedless plants but they have higher developed vascular systems which transport water and minerals. They do not reproduce through seeds, but they reproduce by spores. The dispersion of spores leads to reproduction in the seedless plants.

Option a. is given as “lycophytes”.

As, “The lack of seeds is a characteristic of all lycophytes”, is the right answer.

Hence, option a. is correct.

Reasons for the incorrect statements:

Option b. is given as “conifers”.

The largest gymnosperm phylum is the conifers which include pines, firs, and cedars and so on. The conifers have naked seeds. So, it is a wrong answer.

Option c. is given as “tracheophytes”.

The tracheophytes show two types of reproduction: by seeds and by spores. The tracheophytes also have well developed vascular system in seedless plants. So, it is a wrong answer.

Option d. is given as “gnetophytes”.

The gnetophytes are the gymnosperms and seeds of gnetophytes are most common because they are used in cooking and eating. So, it is a wrong answer.

Hence, options b., c., and d. are incorrect.

Conclusion

The conifers and gnetophytes both have seeds, tracheophytes may have seeds or spores but all the lycophytes are seedless.
