- Production of Offspring
- Sexual Reproduction
- Asexual Reproduction
- Sexual Reproduction
- The use of sex cell or gametes.
- Genetic Variability
- Relatively slower
- Asexual Reproduction
- Does not make use of sex cells or gametes.
- Parents with similar offsprings.
- Types of Asexual Reproduction
- Binary Fission
- Budding
- Fragmentation
- Binary Fission
- Involves the division of the body into two or more equal parts
- Usually occurs in single-celled organisms (Prokaryotes).
- Budding
- a new individual arises as an outgrowth (bud) from its parent, develops organs like those of the parent and detaches itself.
- Fragmentation
- a body breaks into two or more parts with each fragment capable of becoming complete individual.
- follows regeneration where the missing parts are produced.
- Asexual Reproduction
- one parent is involved
- No need for gamete union
- Genetically identical to parent (clone)
- Sexual Reproduction
- two parents are involved
- Gametes are present; sperm cells has to fertilize the egg cells.
- Generally are hybrids of parents (independent assortment).
- Reproductive Organs
- Male Reproductive Organs
- Female Reproductive Organs
- Male Reproductive Organ
- produces sperm cells (spermatogenesis)
- regulated by hormones
- varies from species to species
- Male Reproductive Parts
- Testes
- Seminiferous tubules - produces sperm cells
- Regulated by hormones (GnRH, Follicle-stimulating hormones, and Luteinizing Hormones)
- Female Reproductive Organs
- Ovaries
- Fallopian tubes or Oviducts
- Uterus (Womb)
- Vagina
- Cervix
- Ovaries
- Oogenesis - development of ovarian follicles
- Secretion of hormones.
- Progesterone - hormones during pregnancy.
- Estrogen - development of sex organs
- Fallopian Tubes or Oviducts
- site of fertilization
- Uterus (Womb)
- Endometrium
