• Write characteristics of protists. Who proposed kingdom Protista?
• What do you know about giant amoeba?
• How zoo-flagellates obtain their food? What is the habitat of zoo-flagellates?
• What are choanoflagellates?
• What do you know about green algae? Give two examples.
• What are limestone deposits? How are they formed by foraminifera?
• Draw life cycle of polycephalum (Slime mold).
• Write two characteristics of Apicomplexans. Write the name of apicomplexans that cause malaria.
• What are three major groups of protists? Give at least two examples of each group of protists.
• Why Green algae are considered ancestral organisms of green land plants?
• Write two differences between algae and plants.
• What characteristics of kingdom Protista exclude it from other kingdom?

• What are the functions of micronucleus and macronucleus in ciliates?
• Define the Following terms: 1. Trypanosoma 2. Conjugation 3. Thallus
• Name the pigments present in diatoms.
• Which protists cause diseases in humans?
• What cause red tides? Also define kelps.
• How are protists important to humans? What is their ecological importance?
• How protozoans are helpful in Sanitation.
• differentiate between algae and fungi. These are photosynthetic protists. Chlorophyll and chloroplast is present in them. • Fungi are heterotrophic. They lack chlorophyll and chloroplasts. • Their cell wall is made up of cellulose. • Their cell wall is made up of chitin. • Body may be unicellular, thallus or filamentous. • Their body is composed of hyphae. • Their reserve food material is starch. • Their reserve food material is glycogen. 
• what are diatoms? Write their ecological importance. Ans: Diatoms: The algae in which organism in covered by two overlapping shells are called diatoms. • The cell of each diatom consists of two shells that fit together like a petri dish. • The shell contains silica and this glass like material is laid down in complex patterns. Ecological importance of diatoms: These are the largest producers of marine and freshwater ecosystem because of their large number.
• what are choanoflagellates? Ans: Choanoflagellates: Choanoflagellates are sessile marine or freshwater flagellates. • A stalk attaches these and a delicate collar surrounds their single flagellum. • They closely resemble the collar cells in sponges (hence regarded as ancestor of kingdom Animalia).
• Amoeba move and obtain food by means of:  a) Plasmodium  b) Flagella  c) Cilia  d) Pseudopodia  e) Gamentangia
• Parasitic protozoans that form spores at some stage in their life belong to which group: a) Ciliates  b) Actinopods  c) Diatoms  d) Apicomplexans  e) Zooflagellates
• The feeding stage of slime mold is called:  a) Mycelium  b) Pseudopodium  c) Hyphae  d) Plasmodium  e) Rhizoids
