Year 12 Biology Coursework; Why does raw turnip taste sweeter than raw potato?

Problem:

In the following experiment I am going to puree and determine- Why does raw turnip taste sweeter than raw potato. I will find this egress using osmosis.

Background Knowledge:

We already know that the average concentration of dissolved sugar in turnip is 0.62M. We found this from a previous class investigation. apply Osmosis, which we were taught last year in school, we can find out if potato contains less sugar than turnip, therefore explaining why turnip is sweeter than potato. If we measure the isotonic of both specimens then we can choke a graph comparing the two, therefore making it a lot more easier to distinguish which has the high gearest concentration of dissolved sugar.

Plant stalls expect a prison cell surface membrane. Outside this there is the cellulose cell wall. Inside a plant cell there is a solution of solutes, many of which can be found in the vacuole. In plants water system flows through the cell wall and cell surface membrane into the vacuole from the outside. This causes the cell wall to swell up, further the cell does not burst. The cell is now fully turgid.

Osmosis- Osmosis is a special type of diffusion. It is the movement of water molecules from an area of high concentration to an area of low concentration across a partially permeable membrane.

The diagram on the right invents osmosis.



The water molecules will diffuse into the cell, where there arent as many of them. The solute molecules represent the sugar molecules, inside and outside the cell.

There are three distinguishable types of states a plant cell can be in during Osmosis. They are- Hypertonic, Isotonic, and Hypotonic.

Hypertonic-

When a plant loses water, it becomes flaccid. This always happens when the plant is put in a high concentrated water solution. The inside of...
