Reproduction of Cells Flashcards
centromere separate
anaphase
division of nucleus
karyokinesis
packages DNA into chromosomes
prophase
1/2 of each chromosome (chromatid) moves to the opposite pole
anaphase
term used when a cell has half the usual number of chromosomes
haploid
comprises 75% of the cell cycle
interphase or preparatory phase
nuclear membrane reappear
telophase
four haploid cells have a nucleus with a haploid number of chromosomes
meiocyte cells
2 nuclei form
telophase
cell wall pinches in to form from the 2 new daughter cells
telophase
continuous process to replace cells that die from normal wear or accidents
cell division
chromosomes line up at the center of the cell or at the equatorial plane
metaphase
a cell organism that has paired chromosomes, one from each parent
diploid
2 main phases of the cell cycle
interphase and mitosis
gamete formation
gametogenesis
four phases of mitosis
- prophase
- metaphase
- anaphase
- telophase
what are germ cells
egg and sperm cells
phase where cells increase in size and maintain normal metabolic function
G1
formation of male gametes
spermatogenesis
phase where DNA is represented 2c becomes 4c and the synthesis phase
S phase
identical copies of parent cells
daughter cells
interphase is composed of:
- G1
- S phase
- G2
division of cytoplasm
cytokinesis
phase where RNA and proteins are formed; storage of proteins
G2
what cells does mitosis produce?
cells for growth and tissue repairs
spindle fibers attach to chromosomes at the centromere
metaphase
centrioles move to the opposite pole
prophase
nuclear membrane degenerate
prophase
DNA spreads out
telophase
spindle fibers pull chromosome apart
anaphase
cell division by which germ cells are produced
meiosis
spindle fiber appear
prophase
process whereby a haploid cell is formed from a diploid cell through meiosis and cell differentiation
gametogenesis
the result of meiosis
meiocyte cells
spindle fiber degenerate
telophase
cell division involved in the production of multicellular adult from a zygote
mitosis
formation of ovum or eggs
oogenesis
