Listen to the audio pronunciation in English. Anonymous. It is often found as green clumps, although each strand is microscopic. Is it spirogyra and what’s the best way to get rid of other than physical removal. The male gamete squeezes through the conjugation tube and gets passed into the female gamete thus forming a diploid chromosome structure (2n) called zygote. With reference to the process, spirogyra conjugation is of two t… With cell enlargement and subsequent mitosis, each fragment grows and develops into a mature filament. It is of two types: a) Scalariform Conjugation: Here the two participating cells or gametes with a haploid number (n) of chromosomes come in close contact and develop a small tube-like structures called papillae that fuse to form a bridge connecting the two cells known as conjugation tube. History. A bunch of Spirogyra filaments will clump together forming a mat. You can also see that the individual Spirogyra cells link together to form long filament chains.

Asexual reproduction is thus a form of adaptation in Spirogyra. After fragmentation, the vegetative filament develops into a new filament where each fragment undergoes multiple division and elongation to form a new filament. They move slowly in the liquid medium and are also capable of orientation towards light. In the former type, the filament undergoes fragmentation resulting in numerous filaments.
