Term
Define Asexual Reproduction
Definition
Single parent - genes of offspring are identical to parent's (except for mutations.
Term
Define Sexual Reproduction
Definition
fusion of two types of gametes (egg and sperm) produces offspring.
Term
Advantages & Disadvantages of Asexual Reproduction
Definition
Advantages - energy efficient, most successful in a stable environment.
Disadvantages - lack of genetic variability
Term
Advantages & Disadvantages of Sexual Reproduction
Definition
Advantages - genetic variability, adaptive in unstable, changing environment
Disadvantages - energy consumption, mutations may occur, not as rapid or efficient, fewer offspring at a time
Term
Describe binary fission asexual reproduction
Definition
The mother cell divides into two daughter cells.
(ex. Amoeba, Euglena & Heliozoa)
Term
Describe budding asexual reproduction
Definition
Part of a parents body grows, detaches
(ex. Hydra, sponges )
Term
Describe fragmentation asexual reproduction
Definition
Parent's body breaks inot pieces, each piece can develope into a new animal
(ex. flatworms, annelids)
Term
Describe parthenogenesis asexual reproduction
Definition
Unfertilized egg develops into adult ("virgin development)
(ex. honeybees, wasps, crustaceans)
Term
Describe identical twinning asexual reproduction
Definition
The embryo or larva itself spits into seperate individuals
(ex. some parasitic animals, and also in humans)
Term
Why is fraternal twinning considered to be sexual reproduction and NOT asexual reproduction?
Definition
Because in fraternal twins there are two seperate eggs and two seperate sperm.
Term
Identify and describe the seminiferous tubules.
Definition
Coiled tunules in the testes in which spermatogenesis takes place in male vertebrates
Term
Identify and describe the interstitial cells.
Definition
The cells between the seminiferous tubules which secretes tesoterone
Term
Identify and describe the epididymis.
Definition
A large coiled tube connecting the seminiferous to the vas deferens, sperm maturation and storage
Term
Identify and describe the vas deferens.
Definition
A sperm duct that extends from the scrotum through the inguinal canal into the pevic cavity, sperm maturation and storage
Term
Identify and describe the ejaculatory.
Definition
Term
Identify and describe the urethra.
Definition
The tube that conducts urine from the bladder to the outside of the body, in males the way semen exits the body.
Term
Identify and describe the seminal vesicles.
Definition
In mammals, glandular sacs that secrete a component of semen (seminal fluid). In some invertebrates, structures that store sperm.
Term
Identify and describe the prostate gland.
Definition
a gland in male animals that produces an alkaline secretion that is part of the semen.
Term
Identify and describe the bulbourethral glands.
Definition
located on each side of the urethra, releases a mucus secretion that lubricates the penis.
Term
Identify and describe the scrotum.
Definition
The external sac of skin found in most male mammals that contains the testes and their accessory organs.
Term
Identify and describe the testis.
Definition
The male gonad that produces sperm and the male hormone testosterone; in humans and certain other mammals; the testes are located in the scrotum.
Term
Identify and describe the penis.
Definition
The male sex organ of copulation in reptiles, mammals and a few birds.
Term
Identify and describe the ovary.
Definition
In animals, one of the paired female gonads responsibile for producing eggs and se hormones.
Term
Identify and describe the ostium.
Definition
A small opening or orfice, as in a body organ or passage
Term
Identify and describe the fimbriae.
Definition
the branched fingerlike projections at the distal end of each of the fallopian tubes. Serve to move the ovum toward the uterus.
Term
Identify and describe the infundibulum.
Definition
a funnel-shaped structure or passage
Term
Identify and describe the oviduct.
Definition
The tube that carries ova from the ovary to the uterus, cloaca, or body exterior.
Term
Identify and describe the uterus.
Definition
The hollow, muscular organ of the female reproductive tract in which the fetus undergoes development.
Term
Identify and describe the endometrium.
Definition
The uterine lining
Term
Identify and describe the cervix.
Definition
Lower part of the uterus, extends to the vagina.
Term
Identify and describe the vagina.
Definition
The elastic, muscular tube, extending from the cervix to its external opening, that receives the penis during sexual intercourse and serves as the birth canal.
Term
Identify and describe the vaginal opening.
Definition
The external opening of the vagina
Term
Identify and describe the labia majora.
Definition
Thicker skin external to the labia minora.
Term
Identify and describe the labia minora.
Definition
Liplike folds that surround the vaginal and urethral openings.
Term
Identify and describe the cliotoris.
Definition
A small, erectile structure at the anterior part of the vulva in female mammals, homologus to the male penis.
Term
Identify and describe the corpus luteum.
Definition
The temporary endocrine tissue in the ovary that develps from the ruptured follicle after ovulation, secretes progesterone and estrogen
Term
Identify and describe the graafian follicle.
Definition
A mature ovarian vesicle, that ruptures during ovulation to release the ovum.
Term
Identify and describe the placenta.
Definition
The partly fetal and partly maternal organ whereby materials are exchanged between fetus and mother in the uterus of placental mammals.
Term
Describe the causes, signs & symtoms, treatment for HPV.
Definition
Term
Describe the causes, signs & symtoms, treatment for Chlamydia.
Definition
Term
Describe the causes, signs & symtoms, treatment for Gonorrhea.
Definition
Term
