The Chemical Constituents of Cells

The Chemical Constituents of Cells

Background Information
Mr. Barrett gave us a sheet on staining cells this helped us with the understanding of the experiment. We also did an experiment in class on potato cell, and in our findings we found starch. We also researched the foods and found that glucose is in the apple pulp.

Question
Are the following compounds found in everyday foods?
Protien, Glucose, Starch, lipids & sodium chloride

Hypothesis
My Hypothesis is that protein will be found in the milk & bread , Glucose in the apple pulp & bread, Starch in the bread & potato, Lipid in the milk & bread and Sodium chloride in the potato & bread.

Aim
To identify a range of chemicals found in potato pulp, apple pulp, milk and bread.

Method
The method will be broken into two parts:
1. The testing of standard chemicals.
Put two test tubes (medium) into a test tube holder, add a chemical (E.g. glucose, starch) into each test tube. In each test tube put water as a control...
