Unit 5: Locomotion and Reproduction in Protozoa — Online MCQ Test

Q: What is the temporary cytoplasmic projection used by Amoeba for movement called?

Answer: C. Pseudopodium — Amoeba moves by forming pseudopodia, which are temporary finger-like projections of cytoplasm. They help in both locomotion and capturing food.

Q: Which locomotory organelle is long, whip-like, and typically one or few in number in protozoans?

Answer: B. Flagella — Flagella are long, whip-like structures used for movement in many protozoans. They usually occur singly or in small numbers.

Q: When an Amoeba moves, the endoplasm flows into the pseudopodium due to:

Answer: B. Streaming of cytoplasm — Amoeboid movement occurs due to cytoplasmic streaming, in which endoplasm moves into the pseudopodia. This results in forward movement.

Q: In protozoa, sexual reproduction is mainly associated with the process of:

Answer: A. Conjugation — Conjugation is a sexual process in which two individuals come together and exchange nuclear material. It leads to genetic recombination.

Unit 5: Locomotion and Reproduction in Protozoa — Important Questions & Answers (FAQ)

Frequently asked questions from Telangana State Board CLASS 11 INTERMEDIATE 1 YEAR ZOOLOGY — Unit 5: Locomotion and Reproduction in Protozoa, with answers and explanations. These are sample questions; the exam has its own separate question set.

What is the temporary cytoplasmic projection used by Amoeba for movement called?

A. Flagellum
B. Cilium
C. Pseudopodium ✓
D. Undulipodium

Answer: C. Pseudopodium
Amoeba moves by forming pseudopodia, which are temporary finger-like projections of cytoplasm. They help in both locomotion and capturing food.

Which locomotory organelle is long, whip-like, and typically one or few in number in protozoans?

A. Cilia
B. Flagella ✓
C. Pseudopodia
D. Axopodia

Answer: B. Flagella
Flagella are long, whip-like structures used for movement in many protozoans. They usually occur singly or in small numbers.

Which of the following is a correct difference between pseudopodia and flagella?

A. Pseudopodia are permanent, flagella are temporary
B. Pseudopodia are used only in reproduction
C. Pseudopodia are temporary projections; flagella are slender locomotory organelles ✓
D. Both are non-living structures

Answer: C. Pseudopodia are temporary projections; flagella are slender locomotory organelles
Pseudopodia are temporary extensions of cytoplasm, while flagella are specialized slender structures for movement. Both are living cell structures.

When an Amoeba moves, the endoplasm flows into the pseudopodium due to:

A. Contraction of cilia
B. Streaming of cytoplasm ✓
C. Formation of flagella
D. Cell wall rigidity

Answer: B. Streaming of cytoplasm
Amoeboid movement occurs due to cytoplasmic streaming, in which endoplasm moves into the pseudopodia. This results in forward movement.

In protozoa, sexual reproduction is mainly associated with the process of:

A. Conjugation ✓
B. Binary fission
C. Multiple fission
D. Mitotic budding

Answer: A. Conjugation
Conjugation is a sexual process in which two individuals come together and exchange nuclear material. It leads to genetic recombination.
