Chapter 6: Reproduction – The Generating System — Online MCQ Test

Q: Which of the following is an example of asexual reproduction in plants?

Answer: B. Vegetative propagation through runners — Vegetative propagation through runners (like in strawberry plants) is asexual reproduction as it involves only one parent and no gamete fusion.

Q: Binary fission is a mode of asexual reproduction seen in which organism?

Answer: B. Bacteria — Binary fission is the primary method of asexual reproduction in bacteria, where one cell divides into two identical daughter cells.

Q: Budding is a form of asexual reproduction where a small outgrowth develops on the parent organism. Which organism commonly reproduces by budding?

Answer: B. Yeast — Yeast reproduces by budding, where a small daughter cell forms as an outgrowth on the parent cell and eventually separates.

Chapter 6: Reproduction – The Generating System — Important Questions & Answers (FAQ)

Frequently asked questions from Telangana State Board CLASS 10th BIOLOGY — Chapter 6: Reproduction – The Generating System, with answers and explanations. These are sample questions; the exam has its own separate question set.

Which of the following is an example of asexual reproduction in plants?

A. Pollination and fertilization
B. Vegetative propagation through runners ✓
C. Formation of seeds through meiosis
D. Fusion of male and female gametes

Answer: B. Vegetative propagation through runners
Vegetative propagation through runners (like in strawberry plants) is asexual reproduction as it involves only one parent and no gamete fusion.

Binary fission is a mode of asexual reproduction seen in which organism?

A. Amoeba
B. Bacteria ✓
C. Yeast
D. Hydra

Answer: B. Bacteria
Binary fission is the primary method of asexual reproduction in bacteria, where one cell divides into two identical daughter cells.

Budding is a form of asexual reproduction where a small outgrowth develops on the parent organism. Which organism commonly reproduces by budding?

A. Amoeba
B. Yeast ✓
C. Earthworm
D. Fish

Answer: B. Yeast
Yeast reproduces by budding, where a small daughter cell forms as an outgrowth on the parent cell and eventually separates.

Compare the menstrual cycle and the estrous cycle. Which statement is CORRECT?

A. Both occur in all mammals with the same duration
B. Menstrual cycle occurs in primates and some mammals; estrous cycle occurs in most other mammals ✓
C. Menstrual cycle and estrous cycle are identical in all aspects
D. Only the estrous cycle involves ovulation in mammals

Answer: B. Menstrual cycle occurs in primates and some mammals; estrous cycle occurs in most other mammals
The menstrual cycle is specific to primates (including humans) and a few other mammals, while the estrous cycle is found in most other mammals; they differ in duration and physiological processes.

A student observes that hydra reproduces by budding. If environmental conditions suddenly become unfavorable (food scarcity, temperature drop), hydra may switch to sexual reproduction. What is the MAIN evolutionary advantage of this reproductive flexibility?

A. Sexual reproduction is faster than budding
B. Genetic variation from sexual reproduction increases chances of survival in changing environments; budding alone would produce clones vulnerable to the same stress ✓
C. Asexual reproduction requires more energy than sexual reproduction
D. Sexual reproduction eliminates the need for budding entirely

Answer: B. Genetic variation from sexual reproduction increases chances of survival in changing environments; budding alone would produce clones vulnerable to the same stress
The ability to switch from asexual to sexual reproduction allows organisms to generate genetic diversity through sexual reproduction when facing environmental stress, increasing the likelihood that some offspring will have traits suited to survive new conditions.
