O’simliklarda jinsiy hujayralarning shakllanish jarayoni 2 bosqichga bo’linadi:
1-bosqich — sporogenez — gaploid sporalarning hosil bo’lishi;
2- bosqich -- gametogenez — gametalarning rivojlanishi bilan tugallanadi.
O'simliklarda mikrosporalar hosil bo’lish jarayoni mikrosporogenez,
megasporalarning hosil bo’lish jarayoni esa megasporogenez deb ataladi.
