- Eukaryotic and mostly unicellular
- Multicellular and autotrophic
- Prokaryotic and multicellular
Q2. An amoeba moves and captures food using:

- Pseudopodia (false feet)
- Tentacles
Q3. The mode of nutrition in Amoeba is:
- Autotrophic
- Holozoic
- Saprophytic
- Parasitic
Q4. Paramecium is covered with tiny hair-like structures called:
- Flagella
- Cilia
- Pseudopodia
- Setae
Q5. The contractile vacuole in Paramecium helps in:
- Digestion of food
- Excretion and osmoregulation
- Reproduction
- Photosynthesis
Short Answer Questions
Q6. Describe the structure of Amoeba. How does it move and capture food?
Q7. What is a contractile vacuole? Explain its function in Paramecium.
Q8. Differentiate between Amoeba and Paramecium in terms of locomotion, shape, and mode of nutrition.
Q9. Why are organisms like Amoeba and Paramecium placed in Kingdom Protista and not in Animalia or Plantae?
Long Answer Questions
Q10. Draw well-labelled diagrams of Amoeba and Paramecium. Label the following structures in each: cell membrane, cytoplasm, nucleus, contractile vacuole, food vacuole. Explain how each structure helps the organism survive.
Q11. Describe the process of nutrition in Amoeba. How does it capture food, digest it, and expel waste? Explain the role of pseudopodia and food vacuoles in this process.
APPLICATION / ANALYSIS
Q12. A biology teacher shows students two slides under a microscope:
Slide A: An irregularly shaped organism that keeps changing its shape. It engulfs a food particle by surrounding it with temporary extensions of its body.
Slide B: A slipper-shaped organism covered with tiny hair-like structures. It swims rapidly in water and has two nuclei.
(a) Identify the organisms in Slide A and Slide B.
(b) The organism in Slide B has two types of nuclei - a macronucleus and a micronucleus. What is the function of each?
(c) A student argues: "Both organisms are animals because they move and eat food." Do you agree? Give reasons.
Q13. During the monsoon season in India, stagnant water collects in potholes and empty containers. Soon, these water bodies become breeding grounds for mosquitoes and also contain numerous Paramecium and Amoeba.
(a) Why do Amoeba and Paramecium thrive in stagnant water during the monsoon?
(b) How does the presence of these protists indicate the quality of water?
(c) A student suggests adding chlorine to drinking water to kill all protists. Is this a good idea? What are the potential consequences?
