IN THE PROCESS OF CONJUGATION, TWO FILAMENTOUS STRANDS (OR TWO ORGANISMS) OF THE SAME ALGAE SPECIES EXCHANGE GENETIC MATERIAL THROUGH THE CONJUGATION TUBE. AMONG TWO STRANDS, ONE ACTS AS A DONOR AND ANOTHER SERVES AS A RECEIVER. AFTER EXCHANGING THE GENETIC MATERIAL, TWO STRANDS SEPARATE FROM EACH OTHER. THE RECEIVER THEN GIVE RISE TO A DIPLOID ORGANISM. SPIROGYRA CONJUGATION IS OF TWO TYPES - SCALARIFORM AND LATERAL. IN THE FORMER TYPE, TWO COMPATIBLE FILAMENTS COME TOGETHER AND ALIGN SIDE BY SIDE. FOLLOWING THIS BULGES ARE CREATED, WHICH GROW FURTHER TILL THEY TOUCH EACH OTHER. THE MIDDLE CELL WALL IS DISSOLVED LEADING TO FORMATION OF A CONJUGATION TUBE. CONSEQUENTLY, A CONJUGATION CANAL IS FORMED THROUGH WHICH PROTOPLAST OF ONE CELL (CONTAINING MALE GAMETE) IS TRANSFERRED TO THE OTHER CELL (CONTAINING FEMALE GAMETE) AND A DIPLOID ZYGOTE IS FORMED. ;KHJ - AAAAAAABBBBBCCCCC DJ -
