NEET BIOLOGY

Detailed explanation-1: -Nutrition: Various types of nutrition occur among protists. Indeed, they may be either autotrophic or heterotrophic (some may be both). Photosynthetic protists have chloroplasts and are capable of photosynthesis, although not all use the same chloroplast pigments and they often have different chloroplast structure.

Detailed explanation-2: -Protists are eukaryotic, unicellular organisms that belong to the kingdom Protista. All protists are not heterotrophs. They can be autotrophs, heterotrophs, or mixotrophs. Autotrophic protists possess chlorophyll that helps them in photosynthesis.

Detailed explanation-3: -For classification, the protists are divided into three groups: Animal-like protists, which are heterotrophs and have the ability to move. Plant-like protists, which are autotrophs that photosynthesize. Fungi-like protists, which are heterotrophs, and they have cells with cell walls and reproduce by forming spores.

Detailed explanation-4: -The Protista is a large complex grouping of mostly unicellular eukaryotic organisms. They are morphologically diverse and can be found in most terrestrial, aquatic, and marine habitats as free-living forms and as parasites of other protists, of fungi, and of plants and animals.

Detailed explanation-5: -Answer and Explanation: Protists that can be autotrophic, heterotrophic or both are called mixotrophs.
