Spirogyra je rod parožina iz porodice Conjugatophyceae (Zygnemataceae). Sastavljen je od oko 400 vrsta, koje žive u slatkim vodama, stvarajući velike zelene mase.

Izgled

Spirogyra je nitasta alga široka 10-100 mikrometara, dok duljina može iznositi i nekoliko centimetara. Stanična stijenka ima dva sloja. Vanjski je sloj sastavljen od pektina, koji se otapa u vodi i čini algu sluzavom na dodir. Unutarnji je izgrađen od celuloze. Kloroplastima broj varira, te se nalaze na rubovima citoplazme. Spiralnog su oblika, pa tako i algi daju oblik. Svaki kloroplast sadrži nekoliko pirenoida, koji su središta za proizvodnju škroba fotosintezom.

Razmnožavanje

Spirogyra se može razmnožavati spolno i rijetko nespolno. Kod nespolnog iz samo jednog dijela uzastopnim mitozama nastaje nova alga. Spolni način razmnožavanja je konjugacija.

Konjugacija

Dvije niti spirogire oblikuju konjugacijske cijevi. Sadržaj jedne stanice prolazi kroz cijev i spaja se sa stanicom druge niti, te tako nastaje zigospora, koja može preživjeti i u vrlo teškim uvjetima. Nakon nekog vremena počinju rasti nove niti.
