Reproduction involving only one parent, resulting in genetically identical offspring.

Sexual Reproduction

Reproduction involving two parents (male and female), where sperm and egg fuse during fertilization.

Study Notes

Reproduction

  • Reproduction is a biological process to continue a species
  • Two types of reproduction: asexual and sexual

Asexual Reproduction

  • Involves only one parent
  • Offspring are genetically identical to the parent
  • Common in plants
  • Examples: budding, fission

Sexual Reproduction

  • Involves two parents (male and female)
  • Sperm from the male and egg from the female fuse during fertilization
  • Common in animals

Puberty in Humans

  • Period of rapid physical and emotional changes
  • Reproductive organs mature
  • Production of sex hormones
  • Changes differ between boys and girls

Male Reproductive System

  • Parts: bladder, seminal vesicle, vas deferens, penis, urethra, scortal sacs, testes
  • Functions: produce sperm, store urine, transfer sperm, release semen, pathway for urine and sperm

Female Reproductive System

  • Parts: ovaries, fallopian tubes, uterus, cervix, vagina
  • Functions: produce eggs, release eggs, nurture embryo.

Ovulation

  • Release of egg from the ovary
  • Travel through the fallopian tubes towards the uterus

Fertilization

  • Fusion of egg and sperm
  • Occurs in the fallopian tubes
  • Resulting zygote develops into an embryo

Pregnancy

  • Development of embryo into a fetus inside the uterus
  • Placenta provides nutrients to the fetus. The umbilical cord connects the fetus to the placenta
  • Gestational period: about 9 months
