Solution
In Spirogyra , lateral conjugation takes place in between the two adjacent cells of the same filament, of which upper cell functions as male gametangium and the lower cell as female gametangium. The lower cell increases in size but upper cell remains smaller. The content of male cell passes into the female one and as a result zygospore is formed.
