In arthropods, excretion takes place through malpighian tubules. In Platyhelminthes animals, specialised cells called flame cells are responsible for osmoregulation and excretion.
Can you explain the answer of this question below:Flame cells and Malp...
Flame cells and Malpighian tubules are the analogous organ in helminths and arthropods with other insects, respectively.
Flame cells and Malpighian tubules are excretory organs found in different groups of organisms. They perform similar functions of excretion and osmoregulation, but are found in different species.
Flame cells:
- Flame cells are excretory structures found in helminths, which are a group of parasitic worms.
- These cells are primarily responsible for removing excess water and metabolic waste from the body.
- Flame cells have a shape resembling a flame, hence the name. They are lined with cilia that help in the movement of fluids.
- The fluid collected by the flame cells is then expelled through specialized ducts, ultimately getting rid of the waste from the organism's body.
Malpighian tubules:
- Malpighian tubules are excretory organs found in arthropods, which include insects and other related species.
- These tubules are responsible for removing nitrogenous wastes, such as uric acid, from the hemolymph (insect blood).
- Malpighian tubules are located in the digestive system of arthropods, typically in the hindgut.
- They actively transport waste materials from the hemolymph into the tubules, where water and other useful substances are reabsorbed, leaving behind concentrated waste material.
- The concentrated waste material is then eliminated as solid excrement.
Analogy between flame cells and Malpighian tubules:
- Despite being found in different groups of organisms, flame cells and Malpighian tubules have similar functions and serve as excretory organs.
- Both structures are involved in the removal of waste products from the body and play a crucial role in maintaining osmotic balance.
- The presence of analogous organs in helminths (flame cells) and arthropods (Malpighian tubules) demonstrates convergent evolution, where unrelated organisms evolve similar structures to perform similar functions in response to similar environmental pressures.
Overall, flame cells and Malpighian tubules are analogous organs found in helminths and arthropods with other insects, respectively. They are excretory structures involved in waste removal and osmoregulation, despite being found in different groups of organisms.
