This is a list of some of the major vocab in the reproduction unit.
Question | Answer |
---|---|
Asexual Reproduction | Making exact copies of an organism (budding, regeneration) |
Nucleotide | bond together to make nucleic acids such as DNA |
Replication | making an exact copy of something |
Mitosis | one cell dividing into two twin cells |
Cancer | uncontrolled cell mitosis |
Meiosis | creation of sperm & egg cells that are all different from one another |
Diploid (2n) | a cell with a full set of chromosomes (46 chromosomes for humans) |
Haploid (n) | a cell with half of a set of chromosomes (23 chromosomes for humans) |
Gamete | sex cell (sperm or egg) |
Scrotum | controls the temperature of the testes for sperm production |
Prostate Gland/seminal vesicles | secrete (create) fluid that mixes with the sperm to aid in travel |
ovary | creates eggs, estrogen and progesterone |
uterus | builds and sheds its lining during menstruation; site where the baby develops |
oviduct/fallopian tube | tube where egg travels from ovary to uterus |
menstruation | shedding of the uterine lining |
ovulation | release of the egg from the ovary |
fertilization | sperm and egg meet to make a zygote |
zygote | the one diploid cell created from fertilization |
cleavage | a zygote dividing by mitosis to become many cells during development |
differentiation | cells using only certain parts of their 46 chromosomes and therefore begin to look and function differently |
amniocentesis | a test that takes amniotic fluid to test fetal cells for genetic abnormalities |
egg | the female haploid gamete |
embryo | stage of fetal development after differentiation and before the fetus. |
estrogen | female hormone that provides negative feedback to FSH and also promotes the thickening of the uterine lining. |
external fertilization | sperm and egg meet outside of the body...often occurs in fish |
fetus | stage of fetal development after the embryo and before birth of the baby |
internal fertilization | sperm and egg meet inside the body |
negative feedback loop | interaction of two hormones where one hormone stops the creation of another hormone |
placenta | series of blood vessels where materials are EXCHANGED between mother and baby |
progesterone | female hormone that provides negative feedback to LH and also promotes the thickening of the uterine lining. |
sex cells | gametes such as sperm and egg |
sexual reproduction | requires sperm and egg and results in a unique individual |
sperm | male haploid gamete |
testes | production of sperm and testosterone occurs here |
testosterone | the male hormone that causes male sex characteristics |
ultrasound | using sound waves, a visual image of a fetus is created to search for abnormalities in growth |
umbilical cord | where materials travel from baby to placenta. |
