Meiosis Vs. Mitosis 9th grade bio
Transcript of Meiosis Vs. Mitosis 9th grade bio
T DNA condenses to chromosomes(can't read instructions)
Nuclear Envelope dissolves(nucleolus disappears)
Centrioles move to opposite sides of cell and grow microtublets(precedes mitotic spindle) Metaphase Cell forms mitotic spindle- the microtublets connect to the chromosomes and line them up single file in the middle and push them around ** some microtublets are not connected to cromosmes Anaphase Microtublet become shorter and pull the chromosomes in half
Cell becomes longer because the microtublets push against it ***** Just because the chromosomes split in half each half is still considered a chromosome Telophase Cytokinesis occurs, separating the cell into 2 parts
The DNA in the 2 parts(cells) turn back to chromatin
The Cytoskeleton appears (gives shape to cell) Meiosis Mitosis Meiosis Both Asexual Reproduction- every offspring (in this case cells) are the exact same when compared to each other Sexual reproduction- each offspring varies Produces two diploid cells( homologous chromsomes) Produces haploid cells(only one chromosome of a homologous pair)
