Questions and Answers
What cellular process is directly responsible for the production of gametes?
What cellular process is directly responsible for the production of gametes?
- Osmosis, facilitating nutrient exchange
- Meiosis, reducing the chromosome number (correct)
- Binary fission, creating identical copies
- Mitosis, ensuring identical daughter cells
Why is the larger size and immobility of the female gamete (egg) important for successful sexual reproduction?
Why is the larger size and immobility of the female gamete (egg) important for successful sexual reproduction?
- It repels other sperm, preventing multiple fertilizations.
- It contains more nutrients to support the initial development of the zygote. (correct)
- It allows for faster movement to attract sperm.
- It provides a larger surface area for nutrient absorption after fertilization.

Study Notes
- Sexual reproduction involves two parent organisms uniting to create offspring.
- This process requires the creation and combining of sex cells known as gametes.
- The fusion of gametes results in the creation of a zygote which develops into a new individual.
Gametes
- Gametes are produced via meiosis in reproductive organs.
- Eggs are the female gametes, defined by being larger and immobile.
- Sperm are the male gametes, characterized by being smaller and mobile.
Fertilization
- Fertilization is the fusion of sperm and egg, resulting in a zygote.
- Fertilization can occur inside (internal) or outside (external) the female.
