Looking at the four diagrams in the first column, we need to identify whether each represents
asexual or
sexual reproduction.
---
🔹 Diagram 1: Starfish Regeneration (“cut”)
- Shows a starfish being cut into pieces, and each piece regenerating into a whole new starfish.
- This is
regeneration, a form of
asexual reproduction.
- No gametes (sperm/egg) are involved; offspring are genetically identical clones of the parent.
✔ Answer: Asexual
---
🔹 Diagram 2: Sperm + Egg → Zygote → Embryo
- Shows a sperm cell fertilizing an egg cell to form a zygote, which then develops.
- This is
fertilization, the hallmark of
sexual reproduction.
- Involves two parents (male and female gametes), resulting in genetic variation.
✔ Answer: Sexual
---
🔹 Diagram 3: Hydra Budding
- Shows a hydra growing a bud that eventually detaches to become a new individual.
- This is
budding, a common form of
asexual reproduction in cnidarians like hydra.
- Offspring are clones; no gamete fusion occurs.
✔ Answer: Asexual
---
🔹 Diagram 4: Binary Fission in Amoeba
- Shows a single-celled organism (amoeba) dividing into two daughter cells.
- This is
binary fission, a type of
asexual reproduction.
- The nucleus divides (mitosis), then the cytoplasm splits — producing two genetically identical cells.
✔ Answer: Asexual

## 🧠 Key Concept Summary:
-
Asexual reproduction: One parent, no gametes, genetically identical offspring (clones). Examples: budding, binary fission, regeneration.
-
Sexual reproduction: Two parents, involves gametes (sperm & egg), fertilization, genetically diverse offspring.
