• Write characteristics of protists. Ans: The protists are unicellular, colonial or simple multicellular organisms that posses a eukaryotic cell organization. e.g., Algae, Protozoa. 
• How zoo-flagellates obtain their food? Ans: They obtain food either by ingesting living or dead organisms e.g., Euglena, Amoeba or by decomposing organic matter. e.g., Slime Algae. 
• What kind of body algae possessed? Ans: The plant body of algae is thallus i.e., not differentiated into true roots, stems and leave and lack vascular bundles.
• What stage is called plasmodium in slime molds? Ans: The feeding stage of a slime mold is a multinucleate mass of cytoplasm that can grow to 30cm (1 foot) in diameter. This stage is called plasmodium.
• Why Euglena is placed in kingdom protists? Ans: They are placed in kingdom protista because they have chlorophyll and are photosynthetic but at the same time it had cell wall and is motile.
• What are kelps? Ans: The largest brown algae, which are tough and leathery in appearance. Whose leaf like structure called blade, stem like called stipes and root like structure called hold fast.
• Helpful in the Study of Biological Processes: The plasmodial slime mod Physarum Polycephalum is a model organisms that has been used to study many fundamental biological processes, such as growth and differentiation, cytoplasmic streaming, and the function of cytoskeleton.
