The sundew plant has leaves with sticky hairs that trap and digest insects. Digestion of the insects releases phosphates and simple compounds of nitrogen that are used by the sundew plant.

What substance can the sundew plant make using the phosphates?

Phosphates are essential components of several key biological molecules. - **DNA and RNA:** These nucleic acids are polymers of nucleotides. Each nucleotide consists of a sugar, a nitrogenous base, and a phosphate group. The phosphate groups link the sugars together to form the sugar-phosphate backbone of the DNA/RNA strand. - **ATP:** Adenosine triphosphate, the main energy currency of the cell, contains three phosphate groups. - **Phospholipids:** These form cell membranes and contain a phosphate group in their hydrophilic head. Of the options given, only DNA contains phosphate. Cellulose and starch are carbohydrates (C, H, O), and glycerol is part of a lipid (C, H, O).
