Presentation Transcript
slide1

reproduction - fungi

  • Fungi reproduce using spores produced in the sporangium.
  • Spores contain the genetic material for growth of a new organism, protected by a tough coat (หุ้ม). The spores can remain viable for many years. They will germinate when they encounter favourable conditions, including the correct food source.
  • Most spores are produced asexually (การสืบพันธุ์แบบไม่อาศัยเพศ), but under certain circumstances fungi reproduce sexually (การสืบพันธุ์แบบอาศัยเพศ), allowing new strains of fungi to form.

Asexual reproduction - Fungi

  • Fungi may reproduce sexually. Note that most fungi are haploid (มีโครโมโซมหนึ่งชุด)organisms.
  • The hyphae from two parents fuse producing a diploid (มีโครโมโซมสองชุด) zygospore.
  • The zygospore produces a sporangium and produces spores.
  • The spores produced are haploid.

reproduction - yeasts

(single celled fungi)

  • The division of a cell into two identical cells is called fission (การแบ่งตัว). It is one means of reproduction in yeasts that is similar to bacteria.
  • Some yeasts employ budding (หน่อเร็ว), in which a small outgrowth is formed on the parental cell. The bud slowly grows and eventually splits off from the parent cell.

reproduction - bacteria

  • Bacteria reproduce by binary fission (การแบ่งออกเป็นสองส่วน) which means ‘splitting in two’. In complex bacterial cells with paired chromosomes (โครโมโซม), this is achieved by mitosis (การแบ่งเซลล์แบบไมโทซิส).
  • Daughter cells (เซลล์ของลูกสาว) are identical to the parent cell

Binary fission ∙ whaiuritāruarua

  • Binary fission is a quick process (sometimes taking less than 20 minutes)
  • This means that bacteria can exploit favourable conditions very quickly.
