Diagram Of Fallopian Tube Ovary Zygote. The pollen grains consist of a layer of exine and intine enclosing cytoplasm a tube cell and 2 male nuclei. In humans the fertilization process takes place in the fallopian tube.
On maturity of an ovum the follicle and the ovarys wall rupture allowing the ovum to escape and enter the fallopian tube. The female reproductive organs mainly consist of a pair of ovaries oviducts or fallopian tubes uterus and vagina. At the other end of each fallopian tube is a fringed area that looks like a funnel.
W uterus thick walled muscular organ shaped like an upside down pear when fetus develops.
As the egg enters the fleshy fallopian tube muscular contractions and tiny. The mitotic division starts as the zygote moves through the isthmus of the oviduct called cleavage towards the uterus and forms 2 4 8 16 daughter cells called blastomeres. The diagram shows the female reproductive system during the fertile period of the menstrual cycle. Fertilization is the fusion of haploid gametes egg and sperm to form the diploid zygote.
