Describe each step in the process of cellular division?
Interphase, Prophase, Metaphase, Anaphase, and Telophase Interphase: this is where the cell spends 90% of its time during cellular division. It's split into its own phases, G1, S, and G2. This is where replication of chromosomes occur. Non-replicating cells break off separately in the G1 phase, these are cells like neurons which once damaged cannot grow back. Prophase: This is where the chromosomes start to condense, the nucleolus is no longer there, and mitotic spindle begins to form. Metaphase: The spindles have attached to all the chromosomes, and they have met in the middle. Anaphase: The chromosomes begin to pull apart Telophase: The chromosomes start to re-condense, the spindle collapses, and two nuclei are formed. Cytokinesis: This is the division of the cytoplasm, which differs between plants and animals. In animals, the cells pinch apart creating a cleavage furrow. Plants, on the other hand, have a cell wall (which animal cells don't have) which makes them more rigid, and a cell plate forms in the middle during this phase.
