Sexuality in Organisms:
  • Homothallic: In some organisms, there is no morphological or physiological difference in the functional gametes and the gametes belong to the same parent. Such organisms are called homothallic. Example: Mucor mucedo.
  • Heterothallic: When the functional gametes belong to different parents and there is no morphological or physical difference, these organisms are called heterothallic. Example: Rhizopus stolonifer.
  • Hermaphrodite/Bisexual: In most flowering plants, both male and female sex organs occur in the same flower. Such plants are called hermaphrodite or bisexual. Example: Sweet potato.
  • Dioecious plants: In some flowering plants, male and female flowers are borne on different plants. Such plants are called dioecious plants. Examples: Date palm, papaya.
  • Monoecious plants: When both male and female flowers are present on the same plants, they are called monoecious plants. Examples: Maize, coconut.
