Presentation Transcript

  1. 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.

  2. Asexual reproduction fungi

  3. 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.

  4. 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. Video of Budding Yeast

  5. 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

  6. 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. Video of Binary Fission
