Sexual Reproduction

types of sexual reproduction
Types of Sexual reproduction
  • Zygospores
  • A reproductive part of a fungus or mould
  • The hypha is a long branching filament of the fungus
  • The nuclei of two hyphae join to create a zygospore
  • When conditions are right (warmth, moisture, etc.), the zygospore germinates and creates a new fungus.

Bacterial conjugation

  • Bacteria are able to directly transfer genetic material from one cell to another.
  • New characteristics may be created by the combination.
  • New cells with the changes will be created through binary fission
slide4

Sexual reproduction in plants

  • Female part of the plant – pistil
  • Pistil – stigma – where the pollen grains land, style – the connecting tube from the stigma to the ovary, ovary – where the egg is located
  • Male part of the plant – stamen
  • Stamen – filament – the support, anther - the “bulb” that produces the pollen
slide6

When the pollen and egg unite, the fertilized egg is called a zygote.

  • When the zygote undergoes cell divisions, the multicellular organism is now called an embryo.
  • Self-pollination – both male and female parts are on the same plant
  • Cross-pollination – male and female parts are on separate plants.

Sexual Reproduction in Animals

  • Also involve sex cells (sperm and egg). Called gametes.
  • Fertilization may occur inside (humans) or outside (frogs) of the female
  • Advantages?? Disadvantages??
