Vedclass · Answer

(B) $1$. $Equisetum$ (Horsetail) is a pteridophyte and possesses well-developed vascular tissues (xylem and phloem). Thus,option $A$ is incorrect.$2$. $Selaginella$ is a pteridophyte that produces two types of spores (microspores and megaspores),a condition known as heterospory. Thus,option $B$ is correct.$3$. Ferns typically reproduce vegetatively through rhizomes or adventitious buds,not gemmae (which are characteristic of liverworts like $Marchantia$). Thus,option $C$ is incorrect.$4$. $Rhynia$ is a fossil pteridophyte,but the term 'primitive embryophyte' is more broadly applied to bryophytes. While $Rhynia$ is an early vascular plant,$Selaginella$ being heterosporous is the most distinct and textbook-defined characteristic. Thus,option $B$ is the best answer.
