Answer 1

Male reproductive system

• Testes-they are a pair of sperm producing organs.
• seminiferous tubule-It contain two types of cells,male germ cells andsertoli cells.during meiosis sertoli cells line the seminiferous tubule undergo differntiation and converted to sperm
• Epididymis- it is highly convoluted duct behind the testis that connects testicle to vas deferens
• ductus deferenes-it is a tiny muscular tube which carries sperm from epididymis to the ejaculatory duct
• spermatic cord-it is acord like structure that runs from the deep inguinal ring down to each testicle
• seminal vesicle-they are a pair of simple tubularglands posterioinferior to the urinary bladder.
• prostate gland-it is a walnut sized gland located between bladder to secreate prostate fluid component of semen
• corpus spongiosum-they are a mass of erectile tissue alongside the corpora cavernosa whichprevent urethra from pinching closed maintainig viable channel for ejaculation
• corpora cavernosa-they are the two masses of erectile tissue forming bulk of clitoris.

Female reproductive system

• ovaries-they are the female gonads which secrete hormones.protect eggs and release of eggs
• ovarian follicles-it is a roughly spheroid cellular aggregation foun in ovaries which secretes hormone influences menstrual cycle
• uterine tube-they are the structures which transport ova from ovary to uterus each month
• uterus-structure where offspring are conceived in which they gestate before birth
• cervix-it is a cylinder shaped neck of tissue to the uterus.
• it is a muscular tube leading from external genitals to cervix of uterus.
• vulva- external part of genitalia which protects sexual organs
• mammary glands-it is an exocrine gland produces milk to feed young offspring.

Gamatogenesis

• meiosis 1-production of four genetically haploid daughter cells from one diploid parent cell
• meiosis 2-two diploid cells each split into two haploid cells
• haploid-Cell or nucleus having single set of unpaired chromosomes
• spermatogenesis- process in which haploid spermatozoa develop from germ cells in the seminiferous tubules of testes
• oogenesis-it is the development of ovum

Stages of mitosis

• prophase-first phase in which separates the duplicated genetic materialinto two daughter cells
• metaphase- second stage in whichalignment of chromosomes in the equator of the cell before being separated to daughter cells
• anaphase-replicated chromosomes are split and newly copied chromosome moved to opposite poles of the cell
• telophase- final phase that separates duplicated genetic material into two identical daughter cells
