Which is essential for finding the biomass of spinach? a. to calculate the dry weight of the entire spinach plant. b.to calculate the volume of the juice in the spinach plant. c.to calculate the wet weight of the spinach leaves and stem

The best answer is A. To calculate the biomass of a plant, we should always only consider dry weight or oven dried plant parts such as leaves and stem. Net biomass doesn't include water or moisture content of the plant. Certainly, it is not the juice of the spinach plant that we will use since essential plant parts should not be left out.
