Question
In ferns meiosis occurs when
Options
A.spore germinates
B.gametes are formed
C.spores are formed
D.antheridia and archegnia are formed
Solution
In the ferns the sexual reproduction takes place through spores which are borne in sporangia. Sporangium is a diploid structure. It bears diploid spore mother cells which undergo meiosis and produce haploid spores. Each spore contains an outer thick brown wall called exine and a thin inner wall called intine. Spore is the first cell of gametophyte. On germination, It gives rise to a haploid gametophyic stage.
