The different cell cycle stages are distinguished by the purpose of their function and purpose. The 4 stages are G1, S, G2 and M. They all have different functions. G1 is for the growth of the cell. S is for when the cell is duplicating itself. G2 is the preparation of mitosis or meiosis. M is the actual mitoic phase in the cell. The final outcome of mitosis is to have the two split cells that are made with the DNA.
The function of the nucleus is like the control center of the cell. It directs traffic and everything with in the cell. The plasma membranes function is forms the physical boundary between the cell and its environment, so you can think of it as the “skin” of the cell. The cell wall is only in a plant cell and its function is to provide structure. The mitochondrias function is make energy avaiable for the cell. The vacuoles function is to store and transport materials in the cell. Chloroplast is just in plant cells contain the green pigment chlorophyll. They capture light energy from the sun and use it to make food in the form of glucose, for plants. The ribosomes function is in the cytoplasm where proteins are made. The difference between an animal cell and plant cell is animal cells are circular shape while animal cells are rectangular. Animal cells have no cell wall while pant cells do. Lastly animal cells have many small vacuoles but plant cells have one large vacuole. Enzymes are proteins that help to speed up the chemical reaction in the body. All enzymes have very specific functions but has only one reaction that it can help. The body would not work without enzymes the molecules couldn't come together unless they came at each with the perfect angle. In order for enzyme to work they need to find the active site of the enzyeme and that is where the reaction will take place. Next the enzyme finds the substrate then the reaction takes place and then the products leave the active site. The two main factors that inhibit enzyme action are temperature and shape.
