AIIMS 2018 Botany Gymnosperms and Lycopsida MCQ Question
Assertion : Sequoia is longest tree among Gymnosperms.
Reason : All members of lycopsida are homosporous.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not correct explanation of A.
A is true but R is false
A and R are false
Correct Answer
Detailed Explanation
Members of Lycopsida are primarily homosporous, producing a single type of spore that develops into a bisexual gametophyte. However, some species within this group can be heterosporous, producing two distinct types of spores (microspores and megaspores) that develop into male and female gametophytes, respectively. This variability in spore production is essential for understanding plant reproductive strategies and diversity. The other options are not applicable as they do not provide relevant information regarding the spore types in Lycopsida.
