Short questions
Q1. Define holozoic nutrition. Why is Amoeba considered a holozoic organism?
Q2. What is the function of pseudopodia in Amoeba?
Q3. Explain the role of the food vacuole during nutrition in Amoeba.
Q4. A student observes an Amoeba under a microscope while it surrounds a food particle. Which stage of nutrition is being observed? Explain your answer.
Q5. List the five main stages of holozoic nutrition in Amoeba in the correct sequence.
Q6. Compare the process of food intake in Amoeba with the way humans eat food. Mention one similarity and one difference.
Q1. Explain the complete process of holozoic nutrition in Amoeba from food intake to the removal of undigested waste.
Q2. Describe the structure and functions of pseudopodia. Explain how these structures help Amoeba survive in its habitat.
Q3. Compare nutrition in Amoeba and human beings on the basis of food intake, digestion, absorption, assimilation, and egestion.
Q1. During a biology practical, a student observes an Amoeba approaching a food particle under the microscope.
Describe the sequence of events that the student is likely to observe until the undigested food is removed from the Amoeba.
Q2. A science teacher shows two microscopic organisms:
Organism A: Captures food using pseudopodia.
Organism B: Makes its own food using chlorophyll.
Compare the mode of nutrition of both organisms and explain how each obtains food. .
Q3. A researcher places Amoeba in two different laboratory containers:
Container A: Contains plenty of food particles.
Container B: Contains very few food particles.
Based on holozoic nutrition, discuss how the availability of food may influence the feeding activity and survival of Amoeba.
