mallory has four aquatic plants of the same size and species. she submerges each plant in a separate beaker filled with 200ml of water. she then sets each beaker under a different intensity of light. mallory observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 min period. which of the following statements best explains mallorys observations?
cells decompose most quickly under the most intense light
water evaporates from plants from plants fastest under the most intense light
photosynthesis occurs at the highest rate under the most intense light
gases in the leaves of plants expand most under the most intense light.
which stage does glucose get broken down into 2-3 carbon moleules called pyruvate?
light dependent reactions
glycolosis
electron transport chain
krebs cycle
