  1. Cells Explaining

  2. Our experiment • What we did in our experiment was try to find the durability of a cell. What we did was take two types of plant cell: • One was a normal onion root cell that was fresh. • The next was the same type but it had been flash frozen (For a microwave meal)

  3. The onion root • If you look slightly to the left of the pointer there is a perfectly visible onion cell. As you can see there is a solid form around which means a solid cell wall. Then surrounding that cell are many that are alike and they make a pattern.

  4. The flash frozen cell At the pointer again there is what seems to be a cell. The outer wall that you could see in the first slide. Now its misshaped and doesn’t even seem to resemble a cell at all. And when you could see the inside shapes in the previous picture, now it seems to be a mashed and destroyed version.

  5. A very organized line of cells and very secure build of one cell, as you can see it is compact and has a whole cell wall. Compared This cell on the other hand has been almost destroyed be the freezing process. There are no surrounding cells like in the other picture. They have been destroyed. And the cell wall seems to be deformed while the others have one uniform shape.

  6. What we found • When looking at these cells together you can see that freezing a cell does not really preserve it. It deforms the cell wall and destroys the rest of the cell with it. you can see the organization of cells in a non affected plant but in the other the way that there seem to be no surrounding cells.

  7. What is cell respiration? • The main point of cellular respiration is to make a type of energy that the cell can use. The cell processes sugars to make usable energy for the cell. (ATP) • The cell takes glucose and processes it through cellular respiration produces • 6 CO2+6 H2O+and energy • This energy can be used by cells to complete tasks in our body.

  8. How it happens • Glucose (sugar). • 1st Guycolysis is the breaking up the glucose in two. From carbohydrates to Pyruvate. • To do this there needs to be a use of 2 ATPs and generates 4 ATPs, 2 NADHs molecules and 2 h20 molecules.

  9. Continued. • Which enters Krebs cycle which generates 2 ATPs and requires oxygen. The Krebs cycle generates 3 new NADH molecules • Electron transport chain this produces most ATPs 34 and requires oxygen. NADH is carried by ubiquinone. (q) • Each movement causes a hydrogen ion to pass through the membrane. • The byproducts are Nadh’s and Fadh’s • (this produces lactic acid fermentation) • All this is the remaking of the glucose into 38 ATPs.

  10. What is produced ATP (Adenosine Triphosphate Molecule) (This is how our body gets the energy we need to survive)

  11. Working together All of these cells have to work together to create energy for our body. But cells work together to make everything in the body happen it makes our muscle move and all other movement is generated from cells working together . To make a muscle move groups of muscle cells contract and this moves the muscle all together. Muscle cells

  12. Cell Power • In our bodies cells have very precise instructions on what to do and how to complete a task. Some seem more simple like contract a muscle but there are others like take the food we eat and produce energy from the glucose as I show in the cell respiration cycle. This is how we live, adapt, eat, sleep, and function.

  13. There are many different types of cells

  14. Different cells life span change mainly based on how much harm they can come to. For instance skin cells. Skin cells are on the outside of the body and therefore exposed to more elements. This mean its more likely that they are damaged and die. But some other cells are not exposed as much. This is part of what determines cell life expectancy. Cell life

  15. Conclusion. • What I learned in this investigation was • That there is a certain amount of any extreme that a cell can take. When we tested a normal onion cell then a flash frozen one we could see that being flash frozen almost completely destroyed the cell. • Cell respiration. When a cell takes glucose and breaks it down to make energy for the body out of the food we eat. • How cells all work together and have precise instructions on how to complete extremely difficult tasks. • Lastly the complexities of all cells cell types and cell life.
