Sexual reprodution in Spirogyra is an advanced feature because it show...
Explanation:
Spirogyra is a type of green algae that reproduces asexually by fragmentation and sexually by conjugation. Sexual reproduction in Spirogyra is considered an advanced feature because it involves physiologically differentiated sex organs.
Morphologically Different Sex Organs:
During sexual reproduction in Spirogyra, the cells of two different filaments come in contact and form conjugation tubes. Then, the protoplasts of both cells move towards each other and form a conjugation bridge. This bridge connects the two cells and allows for the exchange of genetic material. The cells then divide to form gametes.
The male gamete is called a spermatium and is morphologically different from the female gamete, which is called an oogonium. The spermatium is smaller in size and is motile, while the oogonium is larger in size and is immotile.
Physiologically Different Sex Organs:
The spermatium and oogonium are also physiologically different. The spermatium is capable of movement due to the presence of flagella, while the oogonium is not. The spermatium is also able to produce enzymes that can break down the cell wall of the oogonium, allowing it to fertilize the egg.
Conclusion:
In conclusion, sexual reproduction in Spirogyra is an advanced feature because it involves the development of morphologically and physiologically differentiated sex organs. This allows for the exchange of genetic material and the production of genetically diverse offspring.
