Revise: Uses of GlucosePlants use glucose to make amino acids, the building blocks of proteins. Glucose alone is not enough: plants also need nitrate ions, which their roots absorb from the soil. These provide nitrogen for making amino acids.
A small molecule that can join with other amino acids to form a protein.
Link each product to its purpose: starch and fats or oils for storage, cellulose for stronger cell walls, and amino acids for protein synthesis.
Distinguish plants making amino acids from glucose and nitrate ions from animals obtaining amino acids by digesting proteins.
A gene codes for a particular sequence of amino acids to make a specific protein; it does not directly code for a characteristic.
