Detailed explanation-1: -Sargassum reproduces vegetatively and sexually. Asexual mode of reproduction is absent. Vegetative Reproduction: Two species of Sargassum, S. natans and S.

Detailed explanation-2: -The deuteromycetes, commonly called molds, are “second-class” fungi that have no known sexual state in their life cycle, and thus reproduce only by producing spores via mitosis, This asexual state is also called the anamorph state.

Detailed explanation-3: -Solution: Asexual reproduction is absent in Ctenophora because the ctenophores reproduce by sexual means.

Detailed explanation-4: -These algae reproduce asexually by fragmentation; when wind, waves, animals or boats break up the floating mats, small pieces grow into larger ones. Given the right conditions, a fragment of Sargassum can become acres of the stuff.

Detailed explanation-5: -Explanation: • Deuteromycetes are anamorphic fungi and do not have distinct sexes. • Their mode of reproduction is asexual through budding or the formation of spores. Hence, sexual reproduction is absent in deuteromycetes.
