state 4 reasons why eukaryotic reproduction is more complex than prokaryotic reproduction.
|
|
|
|
eukaryotic reproduction involves two types of division, what are they?
|
|
|
|
what are the two types of nuclear division? |
mitosis meiosis |
|
|
describe the phases of mitosis, mentioning chromosomes, chromatids, centromeres, and spindle |
interphase- cell grows and replicate their DNA |
|
|
five major groups of eukaryotes? |
fungi algae water molds slime molds |
|
|
eukaryotic methods of asexual reproduction? x 5 |
budding fragmentation spore formation schizogony |
|
|
eukaryotic methods of sexual reproduction? x2
|
sexually by forming gametes and zygotes
|
|
|
what is chromosome VS chromatin |
|
|
|
how is mitosis different from meiosis |
mitosis = diploid > diploid meiosis I = diploid > haploid meiosis II = haploid > haploid |
|
|
haploid vs diploid |
|
|
|
nuclear envelope may disappear, chromatids, microtubes and spindle fibers form
|
prophase |
|
|
chromosomes in a plane attached to the centromere by spindle fibers
|
metaphase |
|
|
sister chromatids separate and move to the opposite poles |
anaphase |
|
|
nuclear envelope froms around the daughter nuclei
|
telophase |
|
|
meiosis is necessary for ____________ reproduction.
|
sexual |
|
|
two stages of meiosis?
|
meiosis II |
|
|

all protozoa produce _____________ (motile feeding stage); some produce _______.
|
cysts |
|
|
_________, are not reproductive structures. they form trophozoite.
|
cysts |
|
