Many plants have waxy coatings on their surfaces that helps maintain homeostasis. This waxy coating reduces water loss because the coating is not water-permeable. Students analyzed a table of various biomolecules to determine which was most similar to the waxy coating on plants.

Glucose

Answer 1

The biomolecule most similar to the waxy coating on plants is Phospholipid.

Phospholipids make up cellular membranes and have hydrophobic (water-repelling) properties, which is similar to the waxy, water-resistant coatings found on plants that help reduce water loss.
