How do organisms reproduce? (Not finished)

FUCK THIS EDUCATION SYSTEM

What are the two types of Fission?

• Binary fission

• Multiple fission

Fission

• An organism divides into two or more parts, each of which develops into a new individuals

Examples of Binary Fission

• Amoeba

• Leishmania

Example of multiple fission

• Plasmodium

In what organism does binary fission occur in relation to the shape of the organism?

• Leishmania

Fragmentation

• Fragmentation is a form of asexual reproduction where the parent organism breaks into two or more fragments, and each fragment grows into a complete new individual.

Examples of Fragmentation

• Spirogyra

Why cant all multi cellular organisms use fragmentation?

• They are not a random collection of cells

• They have specialised cells serving a certain purpose

• In such a carefully organism structure, cell by cell division is impractical

Regeneration

• If the individual is somehow cut or broken up into many pieces, many of these pieces grow into separate individuals.

Examples of Regeneration

• Hydra

• Planaria

Regeneration is carried through what?

• Through specialised cells

Explain how a new organism is developed through regeneration?

• Specialised mass of cells

• Different cells become various cell types and tissues

• These changes take place in an organised
