Which algae is Anisogamous?
Therefore, the correct answer is spirogyra.
What is isogamous Anisogamous and oogamous?
Isogamy is the fusion of male and female gametes which are similar in size. Anisogamy is the fusion of male and female gametes which are dissimilar in size. Here, either both the gametes are motile or both are non-motile. Oogamy is the fusion of a large non-motile female gamete with a smaller motile male gamete.
Is Ulothrix flagellated?
In Ulothrix, each cell has the ability to reproduce by sexual or asexual means, typically by its flagellated zoospores.
Is Ulothrix an Isogamete?
The isogametes of Ulothrix are biflagellate. Their size is even smaller than micro zoospores. Hence, option A is the correct answer. Note: The most common method of reproduction in Ulothrix is vegetative method.

What is the difference between Anisogamous and Oogamous?
The main difference between anisogamy isogamy and oogamy is that anisogamy is the fusion of gametes in dissimilar size while isogamy is the fusion of gametes in similar size and oogamy is the fusion of large, immotile female gametes with small, motile male gametes.
