Reproduction in Plants — Flashcards

Answer

Reproduction is the biological process by which living organisms produce offspring of their own kind. It ensures the continuity of species on Earth and replaces dead individuals. In plants, it can occ…

Answer

• Vegetative reproduction: New plants arise from vegetative parts like roots, stems, or leaves without gamete fusion. Offspring are clones of the parent. • Asexual reproduction: Involves spores or oth…

Answer

A gamete is a specialized reproductive cell (either male or female) that is haploid and formed by meiosis. In plants, male gametes are found in pollen grains, and female gametes are the egg cells in t…

Answer

Chlamydomonas reproduces asexually through spore formation: • Zoospores: Formed when water is abundant. Flagellated, thin-walled spores released after mitotic division. • Aplanospores: Non-motile spor…

Answer

Isogamy is a type of sexual reproduction where both gametes are morphologically identical (same size and shape) but differ physiologically. In Chlamydomonas eugametos, both parents produce similar-loo…

Answer

Anisogamy is sexual reproduction involving two gametes that differ in size and motility. The smaller, more active one is male; the larger, less motile one is female. Example: In Chlamydomonas braunii,…

Answer

Oogamy is a form of sexual reproduction where there is a large, non-motile female gamete (egg) and small, motile male gametes (sperm). In Chlamydomonas oogamum, the entire female cell acts as an egg, …

Answer

Meiosis occurs in the diploid zygote of Chlamydomonas after it germinates under favorable conditions. The zygote’s nucleus divides meiotically to produce four haploid zoospores, each of which grows in…
