Detailed explanation-1: -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-2: -All protists are eukaryotic organisms. This means that they have a membrane-enclosed nucleus and other cell organelles. Most protists are aquatic, others are found in moist and damp environments. Most are unicellular, however, there are a few multicellular protists such as the giant kelp.

Detailed explanation-3: -Protists get food in one of three ways. They may ingest, absorb, or make their own organic molecules. Ingestive protists ingest, or engulf, ba cteria and other small particles. They extend their cell wall an d cell membr ane around the food item, forming a food vacuole.

Detailed explanation-4: -They are heterotrophic in nature and thus obtain their food from an outside source. They are saprophytes that obtain their nutrients by feeding on dead and decaying organic matter. These protists can be classified into two categories-water molds and slime molds.
