Which type of plant is known for having a life cycle that alternates between haploid and diploid generations? (2021)

Step 1: Understand what haploid and diploid mean. Haploid means having one set of chromosomes (n), while diploid means having two sets of chromosomes (2n).
Step 2: Learn about plant life cycles. Plants have two main stages: the gametophyte stage (haploid) and the sporophyte stage (diploid).
Step 3: Identify the groups of plants that have this alternating life cycle. These include mosses, ferns, and flowering plants.
Step 4: Recognize that in these plants, the gametophyte produces gametes (sex cells), and the sporophyte produces spores.
Step 5: Conclude that all these groups of plants exhibit a life cycle that alternates between haploid and diploid generations.
