Sexual reproduction involving fusion of two cells in Chlamydomonas is
Correct answer: A. Isogamy
- A. Isogamy
- B. Homogamy
- C. Somatogamy
- D. Hologamy
Explanation
The sexual reproduction in Chlamydomonas involving fusion of two cells is isogamy. Isogamy is a type of sexual reproduction in which the gametes are identical in size, shape, and structure. In Chlamydomonas, the gametes are motile and have two flagella. When two gametes fuse, they form a zygote. Homogamy is a type of sexual reproduction in which the gametes are similar in size, shape, and structure, but they have different physiological properties. For example, the gametes may be different in their ability to produce pheromones or to respond to pheromones. Somatogamy is a type of sexual reproduction in which the entire organisms fuse to form a zygote. This type of sexual reproduction is common in algae and fungi. Hologamy is a type of sexual reproduction in which the gametes are morphologically distinct, but they are physiologically similar. For example, the gametes may be different in size, but they have the same ability to produce pheromones and to respond to pheromones.
