Plants and animals have a lot of things in common so much in fact i couldn’t fit half of them into this essay‚ there similarities and differences span from the smallest things like cells to huge thing like the whole organism. One thing that plants and animals both have in common is the fact that they adapt‚ the main thing isn’t that they adapt though it’s why they do it. Animals‚ plants‚ and humans all share the same thing they have a will to live in different ways maybe or some might want to live

In this experiment‚ we worked with potatoes‚ also known as solanum tuberosum (Watkins‚ n.d). Potatoes are starchy crops that provide a lot of energy. For this experiment‚ our hypothesis was: If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The

electronegativity separates 2 hydrogen atoms from catechol‚ oxidizing it and therefore converting catechol to benzoquinone molecules that forms long‚branched chains. The chains are the backbone of the red and brown pigments that cause darkening.

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more

figures 1 and 2. Figure 1 shows the diffusion of water molecules through a selectively permeable membrane from an area of highly concentrated sucrose solution to an area of lower concentrated sucrose solution. Figure 2 shows a concentration gradient‚ in which the water molecules are diffusing down the concentration gradient. Depending on whether the higher concentration of sucrose molecules is on the outside of the selectively permeable membrane

without them the reactions within the cells would occur to slow to sustain life. However there are many factors which affect the rate of enzymes reactions. One of them is pH‚ which influence on the enzyme activity will be the subject of this investigation. Catalase of potato tuber cells will be the enzyme used in the experiment.
