Question

With reference to different types of life cycles which of the following statements is correct?

• A. In haplontic life cycle, meiosis takes place during zygote germination.
• B. All seed - bearing plants follow haplo-diplontic type of life cycle.
• C. In different life cycles, there is an alternation of generations between gamete producing sporophyte and spore producing gametophyte.
• D. In diplontic life cycle, spores develop into sporophytes.

Answer 1

The correct option is A

In haplontic life cycle, meiosis takes place during zygote germination.

In haplontic life cycle, the zygote is formed by the fusion of male and female gamete and the gametophyte is formed from the zygote by meiosis or reduction division. All seed bearing plants exhibit a diplontic life cycle where the diploid sporophyte is dominant and forms the plant body while the haploid gametophyte is highly reduced and borne on the sporophyte.
