Sexual reproduction involving fusion of two cells in Chlamydomonas is [1988]a)isogamyb)homogamyc)somatogamyd)hologamyCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Isogamy involves the fusion of gametes which are morphologically and physiologically similar. They are called isogametes. In Chlamydomonas, two vegetative cells may fuse to form a zygospore and the phenomenon is called as "Hologamy". As a result of fusion of two gametes, zygospore is formed. So the correct answer of your question would be option (D) and not (A)

Answer

A because the male and female gametes are isogametes in chlorophyceae.

Answer

Because the male n female  gamets r similar to each other ;we can't distinguish between them who is male or female gametes so by reproduction isogamy takes place.

Answer

D

Answer

Isogamy means fusion of two gametes of same size
so chlamydomonas produce male and female gamate of same size so fusion between them is termed as isogamy

Answer

In isogamy fusion of male and female gametes are similarly

Answer

Because both gametes of same size

Answer

Sexual reproduction involving fusion of two cells in Chlamydomonas is isogamy.

Explanation:
Sexual reproduction in Chlamydomonas, a unicellular green alga, involves the fusion of two cells. This process is known as isogamy.

Isogamy:
Isogamy is a type of sexual reproduction where the fusion of gametes (reproductive cells) occurs between two individuals that are morphologically and functionally similar. In isogamy, the gametes are usually motile and identical in size and shape. This means that both the male and female gametes are indistinguishable from each other.

Sexual reproduction in Chlamydomonas:
In Chlamydomonas, sexual reproduction occurs through the fusion of two gametes, known as gametogamy. The gametes in Chlamydomonas are biflagellate and are produced by specialized structures called gametangia. The gametangia are formed in response to certain environmental conditions such as nutrient depletion or unfavorable growth conditions.

When the conditions are favorable, the vegetative cells of Chlamydomonas undergo gametogenesis, a process where they differentiate into either male or female gametes. The male gametes are called + (plus) gametes, while the female gametes are called - (minus) gametes.

During sexual reproduction, the + and - gametes are released into the environment and come into contact with each other. They exhibit chemotaxis, a process where they move towards each other by sensing chemical signals released by the opposite mating type. Once the gametes find each other, they fuse together in a process known as fertilization.

During fertilization, the plasma membranes of the + and - gametes fuse, resulting in the formation of a zygote. The zygote then undergoes mitotic divisions to develop into a new Chlamydomonas individual.

Conclusion:
In summary, sexual reproduction involving the fusion of two cells in Chlamydomonas is isogamy, where the gametes are motile and indistinguishable in size and shape. This process allows for genetic variation and the production of new individuals in Chlamydomonas populations.
