2, 4-7 Although deep intramuscular injection into a large muscle is the preferred parenteral route of administration, promethazineâs product labeling states that it may be given by slow IV push, which is the typical method of administration in most hospitals.
Quick Answer. Plants produce oxygen as a byproduct of photosynthesis, the process that plants and other organisms use to create usable energy. Photosynthesis consists of carbon dioxide and water reacting in the presence of energy from sunlight, which produces glucose and oxygen.
Introduction. Photosynthesis is the process by which plants use the energy in sunlight to synthesize material from air and water for growth. In this process violet light is absorbed by chlorophyll, the energy obtained splits water, and oxygen gas is given off by the reaction. 2H 2 O(l) = hydrogen + O 2 (g). The hydrogen remains in the leaf and participates in further reactions. The experiment described here is designed to show that sunlight causes green leaves to produce oxygen.
