NEET BIOLOGY

Detailed explanation-1: -Bacteria may be autotrophic or heterotrophic in their mode of nutrition. Kingdom Protista includes all single-celled eukaryotes such as Chrysophytes, Dinoflagellates, Euglenoids, Slime-moulds and Protozoans. Protists have defined nucleus and other membrane bound organelles. They reproduce both asexually and sexually.

Detailed explanation-2: -Plants reproduce sexually or asexually. Some reproduce with seeds through pollina-tion, others through spores, or even asexually as with rhizomes or tubers. Fungi are multicellular decomposers like mold, moss, and mushrooms, but a few of them can be single celled, like yeast.

Detailed explanation-3: -Most protists are unicellular, microscopic organisms, but a few are complex and multicellular. These are the most diverse (different) organisms according to life cycles, since they reproduce asexually and sexually.

Detailed explanation-4: -Asexual reproduction is seen in protists, fungi, plants, and lower animals.

Detailed explanation-5: -Protists have complex lifecycles which are very different from other eukaryotes, such as humans. The green algae, Spirogyra, shown in Figure below, can reproduce both sexually and asexually.
