Which of the following plant groups is known for having a life cycle that includes alternation of generations? (2022)
Step 1: Understand what 'alternation of generations' means. It is a life cycle that alternates between two different forms: a haploid (gametophyte) stage and a diploid (sporophyte) stage.
Step 2: Identify the plant groups mentioned in the question: Angiosperms, Gymnosperms, and Pteridophytes.
Step 3: Research each plant group to see if they exhibit alternation of generations.
Step 4: Confirm that Angiosperms (flowering plants), Gymnosperms (cone-bearing plants), and Pteridophytes (ferns and their relatives) all have a life cycle that includes both the gametophyte and sporophyte stages.
Step 5: Conclude that all the mentioned groups exhibit alternation of generations.
