plant cells
where are germ cells found
reproductive organs
what becomes tightly packed during cell division
chromosones
stage in mitosis in which chromosones replicate themselfs
prophase
2 new daughter cells being formed
telophase
cell elongates and chromosones move toward poles
anaphase
chromosones pair and exchange genetic material
prometaphase
in meiosis two cell division begins with how many daughter cells
2
chromosones
tightly packed dna
chromatin
unwound chromosones
vegetative reproduction
new organisms arise without seeds or spores
gamete
sex cell
mutation
change in dna system
zygot
diploid cell
haploid cells
single set of chromosonesd
diploid cells
2 sets of chromosones
somatic cells
all cells in body except germ cells
interkinesis
period of rest between meiosis and mitosis

found everywhere, prokaryot
eukarya domain
everywhere, most of worlds living things

recieves oxygen blook and pumps into aorta
right ventricle
recieves deoxgenated blood and pumps into pulmonary artery
