oogamy is seen in a)
volvox b) all species of chlamydomonas c) spirogyra d) fucus
Answers
Answer:
option A and option D
Explanation:
It is seen in both volvox and fucus
Answer:
Chlamydomonas is best example for the evolution of sexual reproduction as the evolution of sex in algae has not taken place in any one phylogenetic line. This has taken place along several independent lines. For example, in Volvocales, where Gonium is isogamous, Pandorina slightly anisogalnous, Eudorina and Pleodorina marked by anisogamy and Volvox oogamous. It is correlated with the evolution from isogamy to oogamy through anisogamy. Whereas on the other hand, in another genus of Volvocales, i.e., Chlamydomonas, where species within the genus show all gradations from isogamy to oogamy, e.g., Chlamydomonas snowiae is isogamous, C. braunii is anisogamous and C. coccifera is oogamous.
