How Do Organisms Reproduce

Step 1: Understanding the Concept:
Fertilization is the fusion of a male gamete (sperm) with a female gamete (ovum) to form a zygote. This process takes place within the female reproductive tract.
Step 2: Detailed Explanation:
After ovulation, the egg is released from the ovary and moves into the Fallopian tube (also known as the oviduct). If sperm are present, fertilization usually occurs in the ampulla region of this tube. The resulting zygote then travels to the uterus for implantation.
Step 3: Final Answer:
The correct option is (c).

Step 1: Understanding the Concept:
Pollination is a physical process in flowering plants that must occur before the biological process of fertilization can take place.
Step 2: Detailed Explanation:
Pollination involves the movement of pollen grains (containing male gametes) from the anther (male part) of a flower to the stigma (female part) of the same or another flower. It can be carried out by wind, water, or animals like bees.
Step 3: Final Answer:
The correct option is (b).
