can ya'll help me with some integrated science studies?

Question

i want to someone to explain these processes not the definition the process of it very breif and simple
1 birth
2 fertilization in plants
3 prenancy

and can you also tell me what is the function of the fallopian tube, ovary, uterus, bladder,pubic bone,vagina,vulva,utheral opeing,cervix,rectum,anus and the endometrial lining in women (reproductive organ)

i dont what u to give a definition or describe how it looks i know its a gon take a while to answer but it would really help me as a 15 year student trying to get her grades back up

Answer 1

Well, your question is a bit unclear, but here's what I think you want:

1. Changing hormones in the mother cause contraction of the muscles of the uterus. The contractions push the fetus through the vagina (birth canal). The baby begins to breathe on its own. Further contractions cause the placenta (afterbirth)and umbilical cord to be pushed out too.

2. Pollen produced in the anthers of flowers is transferred by wind or animals (like bees) to the pistil of a flower. The pollen travels down a pollen tube to the ovary. There it combines with the ovule/egg and fertilization occurs. A seed develops.

3. Usually by means of intercourse, a male deposits semen (containing sperm) into the female's vagina. The sperm propel themselves by flagellation. In the fertile part a the female's reproductive cycle, sperm swim toward the egg. When a sperm combines with the egg in the fallopian tube, fertilization occurs. The fertilized egg begins cell division. This mass travels down the fallopian tube to the uterus and implants itself in the endometrium (lining of the uterus). Now pregnancy has been achieved.

Functions:
Fallopian tube: transport system for eggs to get from ovary to uterus. This is the site of fertilization by sperm.
Ovary: organ which develops and releases eggs. also generates hormones which control the reproductive cycle.
Uterus: "home" for fetus - a protective organ which surrounds developing fetus and during birth process pushes fetus out of body to be "born".
Bladder: Holds urine from kidneys. Must be emptied periodically by urination.
Pubic bone: gives structure and support to the reproductive organs
Vagina: access for sperm to reach egg. access for fetus to get out of mother's body during birth (called "the birth canal").
Vuvla: the external part of female genitalia. "Purpose" depends a bit on your context. Simplest terms: it leads males to the right spot.
Urethral opening: exit for urine and in males exit for semen.
Cervix: produces mucus essential to the sperm reaching the egg. Also the access to the uterus.
Rectum and anus: exit for solid waste (feces).
Endometrial lining: this supports implantation of the blastocyst (result of egg and sperm combination) and supplies the fetus with blood for food, oxygen and waste removal.
