CELL DIVISION Important Formula #1 In case of animal cells‚ cytokinesis takes place through cell furrow (centripetal). Cytokinesis takes place in plants by the formation of cell plate (centrifugal). Important Formula #2 Meiosis causes reduction chromosome number‚ so it is also known as reduction division. CELL RESPIRATION Important Formula #1 For oxidative phosphorylation‚ 2.5 ATP are produced per NADH and 1.5ATP per FADH2. (Approx.) Important Formula #2 Non-germinating live seeds and
