What is alternation of generations?
Understand the Problem
The question is asking for an explanation of the concept of alternation of generations, which refers to a reproductive cycle in some organisms where there is a regular alternation between a sexual phase and an asexual phase. This concept is often discussed in the context of plant biology and other life forms that exhibit both gametophyte and sporophyte stages.
Answer
Alternation of generations involves alternating between haploid gametophyte and diploid sporophyte phases.
Alternation of generations is the life cycle in many plants and algae where they alternate between a haploid gametophyte phase and a diploid sporophyte phase.
Answer for screen readers
Alternation of generations is the life cycle in many plants and algae where they alternate between a haploid gametophyte phase and a diploid sporophyte phase.
More Information
This life cycle alternates between a sexual phase (gametophyte) where gametes are produced, and an asexual phase (sporophyte) where spores are produced.
Tips
A common mistake is confusing the sequence of generations; remember that the gametophyte is haploid and produces gametes, while the sporophyte is diploid and produces spores.
