How does reproduction take place in ULVA?
Correct answer: B. Sexual reproduction in Ulva results in the formation of a diploid zygote.
- A. Asexual reproduction in Ulva typically involves the formation of motile zoospores.
- B. Sexual reproduction in Ulva results in the formation of a diploid zygote.
- C. Ulva reproduces through the fusion of diploid sporophytes.
- D. In Ulva, sexual plants are diploid gametophytes with 26 chromosomes.
- E. In asexual reproduction, a single parent cell forms multiple diploid zoospores.
Explanation
Ulva, commonly known as sea lettuce, can reproduce both asexually and sexually. Asexual reproduction in Ulva involves the formation of motile zoospores, which are haploid. Sexual reproduction involves the fusion of haploid gametes, resulting in the formation of a diploid zygote. Therefore, Option B is correct as it accurately describes the process of sexual reproduction in Ulva. Other options are incorrect as they either misrepresent the reproductive process or provide inaccurate information about Ulva's reproductive structures and chromosome numbers.

About Kingdom Protista
Kingdom Protista contains mainly unicellular eukaryotes, although some forms are colonial or multicellular, with varied nutritional and reproductive methods. Questions examine protozoans, algae and examples such as Amoeba, Paramecium and Euglena, while distinguishing protists from prokaryotes, fungi and true plants.
