Free Kingdom Protista MCQs with Answers
243 Kingdom Protista MCQs from Biology, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Kingdom Protista contains mainly unicellular eukaryotes, although some forms are colonial or multicellular, with varied nutritional and reproductive methods. Questions examine protozoans, algae and examples such as Amoeba, Paramecium and Euglena, while distinguishing protists from prokaryotes, fungi and true plants.

- B. Paramecium
- C. Plasmodium
- D. Trypanosoma
Explanation: Apicomplexa is a large class of parasitic protozoans, many of which are pathogenic to humans and animals.
Correct answer: Plasmodium- A. have cell walls
- B. reproduce asexually
- C. develop from an embryo
- D. possess membrane bounded organelles
Explanation: Protists are a diverse group of eukaryotic microorganisms that are not classified as plants, animals, or fungi.
Correct answer: develop from an embryo- A. Cholera
- B. Malaria
- C. Dysentery
- D. Sleeping sickness
Explanation: Apicomplexa is a class of protozoan parasites known to cause several diseases in humans and animals.
Correct answer: Malaria- A. Diatoms
- B. Actinopods
- C. Foraminiferans
- D. Dinoflagellates
Explanation: The correct answer is diatoms. Diatoms are a group of photosynthetic protists known for their unique silica shells, which are composed of…
Correct answer: Diatoms- A. Is heterotrophic
- B. Possesses two nuclei
- C. Use flagella for locomotion
- D. Is unicellular and eukaryotic
Explanation: Both Euglena and Paramecium are single-celled, eukaryotic organisms, but they differ in how they move and obtain energy.
Correct answer: Use flagella for locomotion- A. Entangle the prey
- B. Enhance water beauty
- C. Form limestone deposits
- D. Exchange genetic material
Explanation: The correct answer is that the cytoplasmic projections help foraminiferans to entangle the prey.
Correct answer: Entangle the prey- A. A common moneran ancestor
- B. More than one moneran ancestor
- C. The heritable genetic changes in viruses
- D. The organic substances of the environment
Explanation: Protists are polyphyletic because they arose from multiple independent evolutionary lines among the first eukaryotes, meaning they trace…
Correct answer: More than one moneran ancestor- A. Fucus and Ulva
- B. Ulva and Spirogyra
- C. Polysiphonia and Fucus
- D. Polysiphonia and Spirogyra
Explanation: The protist group closely related to land plants is green algae, including Ulva and Spirogyra. So option B is correct.
Correct answer: Ulva and Spirogyra- A. Diatoms and Dinoflagellates
- B. Green algae and Zooflagellates
- C. Foraminiferans and Euglenoids
- D. Brown algae and Water molds
Explanation: The correct answer is Option A:diatoms and dinoflagellatesThese groups of protists are primary producers in aquatic ecosystems…

- B. They have rigid cell wall
- C. They are multicellular organisms
- D. They are autotrophic
Explanation: Amoeba is a unicellular, heterotrophic organism without a rigid cell wall. It moves and captures food by extending pseudopodia (false feet).
