Options
- ABrown algae has chlorophyll a and c, and fucoxanthin
- BArchegonia are found in Bryophyta, pteridophyta and gymnosperm.
- CThe red algae usually reproduces vegetatively by fragmentation
- DFusion of two gametes of similar size takes place as in species of Eudorina.
Correct answer
D. Fusion of two gametes of similar size takes place as in species of Eudorina.
Step-by-step solution
Sexual reproduction takes place through fusion of two gametes. These gametes can be flagellated and similar in size (as in Ulothrix ) or non-flagellated (non-motile) but similar in size (as in Spirogyra ). Such reproduction is called isogamous. Fusion of two gametes dissimilar in size, as in species of Eudorina is termed as anisogamous. Fusion between one large, nonmotile (static) female gamete and a smaller, motile male gamete is termed oogamous, e.g., Volvox, Fucus.
