Which types of gametes are found in Spirogyra?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Isogamous and non-flagellated
- Isogamous and non-flagellated gametes are found in Spirogyra, a filamentous green algae. In Spirogyra, sexual reproduction occurs through conjugation, where two filaments align, and their cells form conjugation tubes.
- The gametes are morphologically similar (isogamous) and non-motile (non-flagellated). Once the gametes from two different filaments fuse through these tubes, they form a zygospore, which later undergoes meiosis to produce new filaments.
- This type of reproduction highlights the simplicity of gamete formation in lower plant forms like algae.
