To determine how many nuclei are involved in the process of fertilization in flowering plants, particularly angiosperms, we can analyze the process of double fertilization.1. Understanding Double Fertilization: In flowering
How does the sperm of an angiosperm reach the egg? Summarize the pathway of sperm from the male testes to the uterine tube and the pathway of an ovum from the female ovary to implantation in the uterus. Indicate where fertilization occurs. How is a zygote formed? How is the reproductive ...

the body during orgasm or ejaculation. For this reason it is also sometimes referred to as ejaculate. Semen is usually a white or greyish bodily fluid which carries sperm or the spermatozoa and other enzymes that help the sperm to survive to facilitate successful fertilization of the female egg...
What Is Implantation? Following fertilization, the egg travels down the fallopian tube to the uterus. The uterine lining, or endometrium, is ready to accept the fertilized egg. This journey usually takes about six to eight days to happen. ...
Copulation in bearded dragons is relatively short (lasts only for a matter of a few minutes) and is marked by the male gently climbing onto the female and biting her neck and both of them engaging in a “cloacal kiss”. Fertilization of the eggs happens inside the female’s body. 9. ...
