Spirogyra forms nonmotile gametes. Spirogyra undergoes sexual reproduction using a process called conjugation. First two haploid filaments of opposite mating types (+ and -) line up side by side. Each cell then forms an extension that grows towards a cell on the opposite strand. The tubes fuse forming conjugation tubes. The content from the cell of (-) strain travels through the tube and fuse with the cytoplasm of the cell of the (+) strain. The protoplast (the entire living portion of the cell) of each individual organism thus act as an isogamete until they fuse. The diploid zygote develops the zygospore.
Reproduction can be defined as the process by which an organism continues its species. In the human reproductive process, two kinds of sex cells (gametes), are involved: the male gamete (sperm), and the female gamete (egg or ovum).These two gametes meet within the female's uterine tubes located one on each side of the upper pelvic cavity, and begin to create a new individual.exual reproduction cannot happen without the sexual organs called gonads. Both sexes have gonads: in females, the gonads are the ovaries. The female gonads produce female gametes (eggs); the male gonads produce male gametes (sperm). After an egg is fertilized by the sperm, the fertilized egg is called the zygote.
