Study Notes
Reproduction
- Reproduction is the biological process of creating offspring.
- Two main types: asexual and sexual.
Asexual Reproduction
- Involves only one parent.
- Methods include binary fission and budding.
- Binary Fission: Occurs in single-celled organisms (e.g., Amoeba, Paramecium). The cell divides into two equal halves, each with its own nucleus and cytoplasm.
- Budding: Occurs in multicellular organisms (e.g., Hydra). A new organism grows as an outgrowth (bud) from the parent, which then separates.
Sexual Reproduction
- Requires two parents (male and female).
- Individuals have specific reproductive organs and produce gametes.
- Gametes: Female gamete is the ovum (egg); male gamete is sperm.
- Unisexual Animals: Male and female gametes produced in separate individuals.
- Bisexual/Hermaphrodites: Both male and female reproductive organs in the same individual (e.g., earthworms, snails).
Sexual Reproduction in Humans
- Sexual maturity (puberty) occurs between ages 10-14 (females) and 12-16 (males).
-
Male Reproductive System:
- Testes: Produce sperm; located in the scrotum.
- Sperm Duct/Vas Deferens: Transports sperm.
- Penis: Delivers semen to the female.
-
Female Reproductive System:
- Ovaries: Produce ova (eggs); located in the abdominal cavity.
- Oviduct/Fallopian Tube: Transports ovum to uterus; site of fertilization.
- Uterus: Hollow, muscular organ where the zygote develops.
- Vagina: Muscular tube; birth canal.
Fertilization
- Fusion of male and female gametes to form a zygote.
- External Fertilization: Happens outside the female's body (e.g., frogs, some fish).
- Females release eggs into the water, males release sperm, and fertilization occurs externally. Large number of eggs are required.
- Internal Fertilization: Occurs inside the female's body (e.g., birds, mammals).
- Sperm travels to the egg, often via the female reproductive tract.
Zygote Formation
- Fertilized egg (zygote) develops into a new individual.
- In humans, the sperm fertilizes the ovum in the Fallopian tube.
