The rate of photosynthesis can be determined by measuring the rate that reactants are used up by a plant or by measuring the rate that products of photosynthesis are produced by a plant. How would placing a plant in a dark room for 24 hours affect the rate of photosynthesis? A. The rate of photosynthesis would increase and the plant would take in more water.
B. The rate of photosynthesis would decrease and the plant would produce more sugar.
C. The rate of photosynthesis would increase and the plant would produce more oxygen.
D. The rate of photosynthesis would decrease and the plant would take in less carbon dioxide.

explanation:

telophase and anaphase

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

they had the law tat factories that produces smoke cannot be built near residential buildings.
