Asexual Reproduction in Fungi

• Moulds, yeast, and mushrooms
• Members of the kingdom Fungi
• Contain thin filaments called hyphae
• 3 different methods of asexual reproduction

3
Hyphae
Hyphae are thin filaments that grow over the
surface of organisms and into the bodies of other
organisms to obtain food.
4
Fragmentation
Fragmentation occurs when a small piece or
fragment breaks away from the main mass of hyphae
and grows into a new individual.
5
Budding
A copy of the nucleus is made. A tiny bud (bump)
on the cell wall of the organism (yeast) appears.
The new bud contains the nucleus and the bud
starts to grow larger. Eventually, it breaks
away and becomes an independent cell.
6
Spores
A spore is a reproductive cell that can grow into
a new individual through mitotic cell division.
Spores are stored in a case called a sporangium.
When spores mature, they can be black, blue,
yellow or red.

Asexual Reproduction in Animals

• Members of the Kingdom Animalia
• There are two main groups invertebrates and
  vertebrates
• Vertebrates are animals with backbones
• Invertebrates are animals without backbones
• Not all animals reproduce sexually

Invertebrates

Planaria
Planaria, a type of flatworm, are able to
regenerate parts when they are damaged. They can
reproduce asexually by dividing into two and
regenerating the parts that they are missing.
10
Sea Stars
Sea stars reproduce asexually. They are able to
grow body parts through regeneration.
11
Hydras
Hydras reproduce asexually by budding. A cell,
usually near the base of the organism, will
undergo mitosis and cytokinesis repeatedly to
produce a new bud or organisms. This results in
a colony. Some buds will separate and become
independent organisms.
