Student Response Value Correct Answer Feedback A. both multicellular diploid and multicellular haploid individuals 50% Yes. Plant life cycles involve both diploid and haploid individuals. There are many variations on this general theme in terms of length of the generation, its dependence on the preceding generation for nutrients, and the size of the sporophytes and gametophytes. B. diploid individuals are independent of the gametophytes -50% No. In many plants, the diploid individuals (sporophytes) are entirely dependent on the gametophyte. C. gametes are produced by mitosis, not by meiosis 50% Yes. Unlike animals, plants produce gametes by mitosis. D. only occurs in
