BIOLOGY-ONion root tip activity

Hey , use this to identify the different stages of mitosis as well as to figure out how long a cell spends in each phase. REMember : PMAT ( nuclear division) with cytokinesis ( division of cell cytoplasm) leads to two genetically identical cells ( if it goes well!). YOUR cell spends most of its time in the stage before cell division- INterphase - this is when your DNA is being copied or doubled and getting ready to create two new cells.

Benchmark test on MONDAY- study ecology, scientific method, organic compounds, enzymes, mitosis, nutrient cycling, and my study guides. USe the regents test prep site (look under "useful websites" section on blog).
Also use this link to check out sample EOC questions ( they give you answers at the end so you can self-check).
