What happens in alternation of generations?

Alternation of generations describes a plant’s life cycle as it alternates between a sexual phase, or generation and an asexual phase. The sexual generation in plants produces gametes, or sex cells and is called the gametophyte generation. The asexual phase produces spores and is called the sporophyte generation.

What is an example of alternation of generations?

The fern is an example of alternation of generations, in which both a multicellular diploid organism and a multicellular haploid organism occur and give rise to the other. Alternation of generations is easiest to understand by considering the fern. The large, leafy fern is the diploid organism.

What is the alternation of generations quizlet?

A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants.

Which type of reproduction occurs in protists?

asexual binary fission
The typical mode of reproduction in most of the major protistan taxa is asexual binary fission.

Which of the following is true for alternation of generation?

So, the correct answer is ‘Diploid generation is followed by haploid generation’.

Which of the following occurs during the alternation of generations in plants?

Alternation of generations means that plants alternate between two different life stages, or generations, in their life cycle; a haploid stage called gametophyte and a diploid stage called sporophyte.

What is alternation of generation in bryophytes?

Alternation of generations is a life-cycle involving two phases of life, which regularly alternate with each other. In Bryophytes, the first phase is the gametophytic phase, in which gametes are produced, that contain half the number of chromosomes.

What is alternation of generations biology quizlet?

Alternation of Generations. This term refers to the life cycle of most plants in which the generations alternate between haploid gametophytes and diploid sporophytes. All embryophytes and some algae undergo this process.

Which of the following is characteristic of alternation of generations in land plants?

11) Which of the following is characteristic of alternation of generations in land plants? Meiosis in sporophytes produces haploid spores. plants evolved alternation of generations independently of green algae.

What is alternation of generation in fungi?

alternation of generations, also called metagenesis or heterogenesis, in biology, the alternation of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or generations, are often morphologically, and sometimes chromosomally, distinct.
