We have started osmosis and we have done the osmosis test with potatoes for this task which we will see if the potato will shrink or expand in different sucrose/salt levels with five experimental groups which will have different levels of the salt/sucrose in it. …show more content…
Exosmosis: the exiting of water from an organ, cell or system. • Pros and cons of osmosis: Pros: it improves the filtration of dirty water from using reverse osmosis. Helps certain machines’ work to optimum level in the printing industries. One of the most effective ways to filter water. Cons: Has some serious draw backs. Removes most of the minerals in the water giving it an acidic Ph level. It takes a long period of time 1-1 ½ hours to work. • The ideal environment: An isotonic environment as the cell and the outside of the cell is equal. There will be an equal amount so that the cell won’t burst or be deprived of the water or nutrients needed. • The importance: It is important as it uses the distribution of essential nutrients around the body and the use for the excretion of bodily …show more content…
Question 15: Only the potato in tap water that had no added salt drooped the most water and shrunk the most while the other potatoes did shrink they did not shrink as must therefore my hypothesis was incorrect. Question 16: I could have increased the time so that more action could happen within the potatoes and the water. I could also increase the amount of salt and decrease the amount of water or decrease the salt and increase the water. Question 17: If there is too much salt or sucrose and not enough water the plants and ground bearing food will become deprived of water and die from the high levels of salt or sucrose. That is why there is an equal amount of salt water or sucrose and water. Question 18: https://www.Wikipedia.com>osmosis www.Biologydisscusion.com>essay>essayonosmosis www.dictionary.com>browse>osmosis
