Which statement about Asexual reproduction is false? Asexual reproduction does not involve the formation of specialised reproductive cells. Asexual reproduction can result in offspring that are genetically identical to the parent Asexual reproduction involves the fusion of gametes from two parents Asexual reproduction typically involves a single-parent organism.

Compare the adaptations of male gametes in plants and animals for successful fertilisation. Male gametes in plants (pollen grains) are streamlined with flagellum for mobility, whereas male gametes in animals (sperm) are small and lightweight for transport by wind or pollinators with a tough outer shell Male gametes in animals (sperm) are streamlined with flagellum for mobility, whereas male gametes in plants (pollen grains) are small and lightweight for transport by wind or pollinators, with a tough outer shell Male gametes in plants (sperm) are streamlined with flagellum for mobility, whereas male gametes in animals (pollen grains) are small and lightweight for transport by wind or pollinators, with a tough outer shell
