Which protistan group includes diatoms?
- A. Chrysophytes
- B. Dinoflagellates
- C. Euglenoids
- D. Slime moulds
Which protists possess two flagella and often show cellulose plates on the outer surface?
- A. Dinoflagellates
- B. Chrysophytes
- C. Slime moulds
- D. Amoeboid protozoans
Why are euglenoids described as showing both plant-like and animal-like features?
- A. They are photosynthetic in light but can become heterotrophic when light is absent
- B. They alternate between prokaryotic and eukaryotic organisation
- C. They possess both chitin and cellulose cell walls
- D. They reproduce only by spores and seeds
What feature distinguishes slime moulds from photosynthetic protists during their feeding stage?
- A. They are saprophytic and feed on decaying organic matter
- B. They contain chlorophyll a and b in all stages
- C. They are prokaryotic
- D. They obtain energy only by oxidising ammonia
Diatomaceous earth, used in polishing and in the filtration of oils and syrups, is formed by the accumulation of cell walls of which group of protists?
- A. Chrysophytes
- B. Dinoflagellates
- C. Euglenoids
- D. Slime moulds
A unicellular eukaryote has a flexible pellicle instead of a cell wall and can photosynthesise when illuminated. Which group is the best match?
- A. Euglenoids
- B. Dinoflagellates
- C. Chrysophytes
- D. Slime moulds
A plankton sample contains organisms with silica-rich walls that leave behind large deposits after death. Which group is indicated?
- A. Diatoms among chrysophytes
- B. Euglenoids
- C. Slime moulds
- D. Ciliated protozoans
Match List-I with List-II: List - I Organisms List - II Mode of Nutrition (A) Euglenoid (I) Parasitic (B) Dinoflagellate (II) Saprophytic (C) Slime mould (III) Photosynthetic (D) Plasmodium (IV) Switching between photosynthetic and heterotrophic mode Choose the correct answer from the options given below:
- A. A-III, B-IV, C-II, D-I
- B. A-IV, B-II, C-I, D-III
- C. A-IV, B-III, C-II, D-I
- D. A-IV, B-II, С-III, D-I
A single-celled organism in a pond has two flagella, a flexible protein-rich pellicle instead of a cell wall, photosynthesises in sunlight but behaves as a heterotroph when kept in the dark. Which group is it, and what is the pellicle's consequence?
- A. Dinoflagellate; the stiff plates make it rigid
- B. Euglenoid; the pellicle makes the body flexible
- C. Chrysophyte; the pellicle is siliceous
- D. Ciliate; the pellicle bears cilia
An aquatic protist has two flagella, photosynthetic pigments and an outer covering reinforced with cellulose plates. A second protist lacks a cell wall and has a flexible pellicle. Which pairing is correct?
- A. Dinoflagellate and euglenoid
- B. Euglenoid and dinoflagellate
- C. Chrysophyte and slime mould
- D. Slime mould and chrysophyte
Common mistakes in Protista - the four major groups
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Attaches the gullet-and-cilia description to a flagellate.
- Attributes the red tide to the pigment of a cyanobacterium or an euglenoid.
- Equates the plasmodium of slime moulds with the genus Plasmodium and calls it a sporozoan.
