Q1: 1. Which of the following is an advantage of vegetative propagation (e.g., grafting) in plants that is not possible in sexual reproduction?
It produces greater genetic variation.
It allows propagation of plants (like bananas) that have lost the capacity to produce viable seeds.
It is a slow method of propagation.
The new plants are more resistant to all diseases.
Q2: 2. In Rhizopus (bread mould), the fine thread-like structures (hyphae) spread on the bread. The blob-like structures (sporangia) on top contain:
Gametes
Spores
Zygotes
Buds
Q3: 3. In a flower, the ovule contains the female gamete (egg cell). After fertilization, the ovule develops into the (X) and the ovary develops into the (Y). Identify X and Y.
X: Fruit, Y: Seed
X: Seed, Y: Fruit
X: Embryo, Y: Seed
X: Seed, Y: Flower
Q4: 4. (HOTS) A student observed a permanent slide showing binary fission in Amoeba. Which observation below best describes the process?
A large Amoeba forms a cyst, which then releases many small Amoebae.
A small bud detaches from the parent Amoeba.
The nucleus divides first, followed by the division of the cytoplasm, creating two daughter cells.
Two Amoebae fuse together to form a zygote.
Q5: 5. In the human female reproductive system, where does fertilization (fusion of sperm and ovum) normally take place?
Uterus
Ovary
Vagina
Oviduct (Fallopian tube)
Q6: 6. What is the primary function of the placenta during pregnancy?
To protect the embryo from all infections.
To provide a large surface area for the exchange of nutrients and oxygen between mother and foetus.
To store the sperm before fertilization.
To trigger the process of childbirth (parturition).
Q7: 7. (HOTS) If the vas deferens in a man is blocked (e.g., in vasectomy), which of the following will not occur?
Sperms will not be produced in the testes.
Semen will not be ejaculated.
Sperms will not be transported from the testes to the urethra.
Testosterone production will stop.
Q8: 8. The menstrual cycle in human females is regulated by hormones. The lining of the uterus thickens to receive a fertilized egg. What happens if fertilization does not occur?
The lining thickens further and waits for the next cycle.
The lining breaks down and is discharged (menstruation).
The unfertilized egg implants in the uterus.
The ovary releases another egg immediately.
Q9: 9. Planaria can be cut into several pieces, and each piece grows into a complete organism. This process is called:
Budding
Fragmentation
Regeneration
Spore formation
Q10: 10. Which of the following is a key difference between unisexual flowers (like papaya) and bisexual flowers (like mustard)?
Unisexual flowers have stamens and pistil; Bisexual flowers have only one.
Unisexual flowers cannot be pollinated; Bisexual flowers can.
Unisexual flowers have either stamens or pistil; Bisexual flowers have both.
Bisexual flowers produce seeds; Unisexual flowers produce fruits.
