Fragmentation in Multicellular Organisms Quiz

Study Notes

Reproduction in Spirogyra

Spirogyra reproduces primarily through conjugation, a form of sexual reproduction where two filaments align and exchange genetic material.
Vegetative reproduction occurs through fragmentation, where pieces of filament break off and develop into new individuals.

Organisms Using Regeneration

Regeneration is found in several organisms, including:
- Echinoderms (like starfish) can regenerate lost arms.
- Planarians, a type of flatworm, can regenerate their body segments.
- Some species of salamanders possess remarkable regenerative abilities, including regrowing limbs.

Reproduction in Multicellular Organisms

Multicellular organisms with differentiated tissues and organs typically reproduce through sexual reproduction, involving the combination of gametes from two parents, leading to genetic diversity.
Asexual reproduction methods include budding, fission, and fragmentation in certain species.

Self-Amputation in Reproduction

The method of reproduction involving self-amputation is known as autotomy.
Common in species such as lizards, which can shed their tails as a defense mechanism that can later regenerate.

Commonality of Regeneration

Regeneration is a common method of asexual reproduction in organisms like:
- Hydra, which can reproduce by budding.
- Worms such as earthworms can regenerate segments of their bodies.
- Certain plant species also show a high capacity for regeneration through new growth from cuttings.
