EXTRA STOKE POINTS.....

• 200 types of cells are known in human body.
• Omne Vivum Ex Vivo ,Means all life come from life . This statement given by Pasteur in 1862.
• To become efficient the large cells develops some unique features like development ofmicrovilli, becomes flat , become long gubular .As a result surface area imcreases.
• Each cell requires an inflow of energy for performing different activities, all systems are irreversibly moving towards increasing disorder .this is called law of Entropy( based on 2nd law of thermodynamics).
•  Due to entropy the organisms will die so to overcome entropy there is requirement of continuous inflow of energy thats why the plant synthesize food and we require food.
• cell is an open system.

• Title of Schleiden and Schwann's paper was----Microscopic investigation on the similarity of structure and growth in animals and plants.
