Hint: Bryophytes are a group of non-vascular terrestrial plants having limited size. These plants prefer moist environments for living although they can survive in dry environments too. The plants are divided into three categories - the liverworts, hornworts, and mosses. On the other hand, tracheophytes are popular as vascular plants. They grow large compared to bryophytes since the nutrients can reach each part of the plant body due to the presence of vascular. Eg.- clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants)
Complete answer:
Bryophytes usually reproduce via spores. The reproductive structure is enclosed and termed as gametangia and sporangia. They are also known as embryophytes. In the life cycle of bryophytes, the fertilized eggs produce zygote which later develops sporophyte embryos inside archegonia.
Unlike Bryophytes, Tracheophytes possess a vascular system including xylem and phloem tissues. They also reproduce by spore formation. The reproductive organs are not protected inside the plant rather they are exposed. After fertilization, the sporophyte relies on the gametophyte until its development to roots and shoots. The zygote phase inside the sporophyte is the embryo stage in tracheophytes. Collectively bryophytes and tracheophytes are called embryophytes. Both of them are terrestrial plants. But these two features are not interdependent with each other. Hence, although the above assertion and reason both are correct and the reason is not the correct explanation of the assertion.
So, the correct answer is “Option B”.
Note:
Tracheophytes are taller than bryophytes. This is because of the presence of vascular tissues which make the tracheophytes stay upright and circulate water and food inside the plant through its xylem and phloem tissues. This helps the plant to grow better.
