Cell Division Test Flashcards
Cell Division
the process by which cells devide to make two new daughter cells
asexual reproduction
the production of genetically identical offspring from a single parent
sexual reproduction
offspring produced by sexual reproduction inherit some of their genetic into from each parent
cellular division cause
information overload because dna does not grow along with cells
large cells are less efficient in moving nutrients and waste products across the cell membrane and inside the cell
mitosis
division of the cell in eukaryotic cell division
meiosis
process during cellular division when chromosomes per cell is cut in half
process during cell division in which the nucleus of a cell completes two successive divisions that produces four (gametes) each with a chromosome number that has
differentiation
process in which cells become specialized in structure and function
gamete
sex cell
onad
ovaies and te3stes
ovary
the primary female reproductive organ which produces eggs
testes/testicle
primary male reproductive organ, produces sperm
chromosome
thread like structure of dna and protein that contains genetic info
adaptation
heritable characteristic that increases an organisms ability to survive and reproduce in an environment
fertilization
process by which cells release energy in the absence of oxyge
fallopian tube
a tube that connects the ovary to the uterus
hormone
chemical produced by and organism that affects another part of the same organism
hormone
chemical produced by and organism that affects another part of the same organism
estogen
increases uterus lining
testosterone
causes male physical changes
ovulation
the release of a mature egg from the ovary into one of the fallopian tubes
embryo
developing stage of a multicellular organism
placenta
specialized organ in placental mammals through which respitory guses, nutrients, and wastes are exchanged between the mother and her developing young
chromatin
usual stage of thingy
chromosome
x shaped thingy
chromatid
half of a chromosome
centromere
center of a chromosome that keeps it together
chromosome number of a human
48
interphase
period of cell growth and development
dna replication occurs here
cell grows, carries out normal cell activities, and replicates all other organelles
cell spends most of it’s life in interphase
