Answer:
Carbon dioxide and water are combined to give glucose in the presence of sunlight and oxygen is given off.
Explanation:
In science, matter is neither created nor destroyed but is changed from one form to another.
Photosynthesis has to do with the combination of water and carbon dioxide in the presence of sunlight to form glucose in the light phase of photosynthesis. The glucose undergoes further reactions in the dark phase of photosynthesis to form complex carbohydrates.
The major changes in matter during photosynthesis are; water and carbon dioxide combine to form glucose and secondarily, complex carbohydrates. Oxygen is given out in the process.
Answer: The matter, carbondioxide and water, are inorganic compounds which are convert to organic products( sugar) that are stored in the plant after photosynthesis.
Explanation:
Photosynthesis is the process by which green plants manufacture their own food. The mechanism of this process involves two stages of reactions:
1.) LIGHT REACTION STAGE: This is so called because it occurs in the light. Chlorophyll is energised as it absorbs sunlight energy. The energised chlorophyll splits water molecules into Hydrogen ion and hydroxyl ion( that is, photolysis of water). The hydroxyl ion gives up its negative electron to chlorophyll molecules and forms water and oxygen. The oxygen is given out as a by- product.
2.) DARK REACTION STAGE: this is so called because it doesn't require light. Carbondioxide is reduced by combining with two atoms of hydrogen provided by a coenzyme( NADP H2) to form sugar( an organic product). I hope this helps, thanks.
