GENETICS

Organisms

Single-celled(organism made of only 1 cell)

Multicellular(an organism made of more than 1 cell)

Processes

Prokaryotic-cell with no nucleus

Body cell

Gamete(the product of meiosis; each is unique)

Sperm

Ovum/egg

Humans

Coral(a multicellular organism that does external fertilization and lives in the ocean, they can produce sexually and asexually )

Flowers(have both sexual and asexual reproduction)

Fertilization(when sperm meets egg)

Reproduction

Gametogenesis(the creation of sex cells)

Sexual(produce a unique offspring)

Asexual(results in a clone/identical cell and does not involve another organism to do)

Mitosis(a process that results in a clone/identical cell and is done by body cells; it does division and cell production)

Meiosis(crossing over occurs in this process of division and production of sex cells)

Internal(the gametes meet inside an organism)

External(where the sperm and egg meet outside of an organism)

Cellular differentiation(it is done by body cells, and it's the concept that different proteins made in a cell give it a different role in the organism)

Chicken

Bacteria(single-celled organism that does asexual reproduction and mitosis)

Eukaryotic-organism made of cells with a nucleus

Stages:

  1. Interphase
  1. Metaphase
  1. Anaphase
  1. Prophase
  1. Telophase
  1. Cytokinesis(the last stage that divides the cell to cause the creation of daughter cells)

Cell Development

Ovogenesis(development of ovum cell)

Spermatogenesis(development of sperm cell)

DNA(replicates

Homologous Chromosomes(crossed, the maternal and paternal chromosome that will pair up)

Potato(has asexual reproduction through tubers)

Runner(asexual reproduction by strawberry plants)

Crossing over occurs here

FEMALE reproductive system

MALE reproductive system

Diploid(a cell that pairs chromosomes from each parent-23 pairs of chromosomes)

testis

penis

urethra

vas deferens(a muscular tiny tube that carries sperm from the epididymis to the ejaculatory duct)

epididymis(a tube that stores sperm and transports it to the testis)

prostate gland

uterine lining

cervix(lower part of the uterus in the female, the eggs leaves the body through it)

vagina(the tube leading from the external genitals to the cervix of the uterus)

fallopian tube(One of two tubes that connect the ovaries to the uterus, the egg is released there during ovulation)

ovary(primary female reproductive organ)

uterus

  1. zygote(fertilizied egg formed from when sex cells have met)
  1. embryo
  1. fetus
