You are conducting an experiment on plant growth. You take a plant fresh from the soil that weighs 5 kg. Then you dry the plant overnight and determine the dry weight to be 1 kg. Of this dry weight, how much would you expect to be made up of organic molecules?

Question

Quizplus · Accepted Answer

Most of the dry weight of a plant is composed of organic molecules, primarily carbon-based compounds such as carbohydrates, proteins, and lipids. Typically, about 90-95% of a plant's dry weight is organic material, so 960 grams out of 1 kg is a reasonable estimate.
