Spirogyra (Green Algae): Vegetative Phase
Spirogyra (Green Algae): Vegetative Phase
Spirogyra's vegetative stage is characterized by a filamentous structure with cytoplasmic strands, mucilage-coated cell walls, vacuoles, a nucleus, and a spiral chloroplast.
Spirogyra (Green Algae): Sexual Phase
Spirogyra (Green Algae): Sexual Phase
Spirogyra's sexual reproduction involves conjugation, where protrusions from different filaments meet, forming a conjugation tube and creating a zygospore.Empty cell is formed
