Reproduction Unit
Onion Root Tip Experiment: Preperation
Why do cells reproduce?
-- repair
-- replace dead cells
-- we are growing
What do we expect to see of REPRODUCTION?
-- larger cells
-- more DNA clumps --> chromosone
-- bigger nuclei
-- more organelles
-- splitting cells
Onion Root Tip Experiment: What Happened
-- When we looked under the microscope, we saw many different cells.
+ about to split

+ lots of DNA strands
+ no nucleus ???
+ big nucleus
MITOSIS: When the eukaryotic cell seperates the chromosone and DNA intoo two identical sets.
Phases:
1. Interphase
2. Prophase
3. Prometaphase
4. Metaphase
5. Anaphase
6. Telaphase
7. Cytokinesis
