What is diplontic life cycle class 11

Diplontic life cycle refers to the life cycle of organisms, which is dominated by the diploid stage. Plants and algae show alternation of generation. All the plants showing sexual reproduction alternate between two multicellular stages, viz. Haploid gametophyte and diploid sporophytes.

What is the diplohaplontic life cycle?

The diplohaplontic life cycle of a seed plant has five defining properties: (1) hetero- spory or separate cell lineages for male and female reproduction, (2) multicellular gametophytes, (3) retention of the female gametophyte within the adult sporophyte, (4) the pollen tube and (5) dispersal of mature embryos.

What is a diplohaplontic life cycle give an example?

Note: Gymnosperms have a diplohaplontic life cycle, i.e. there are two phases - first is the dominant and sporophyte phase and the second is the brief gametophyte phase, whereas algae have a haplontic life cycle i.e. they have only meiosis.

What is haplontic life cycle 11th?

The haplontic life cycle refers to the life cycle of organisms, which is dominated by the haplontic stage or a stage characterized by a single set of chromosomes. Alage shows haplontic life cycle. Alternation in the generation is shown by algae and plants.
