How does h2o Help photosynthesis?
Water is one of the most essential parts of photosynthesis. Six water molecules react with six carbon molecules to form one molecule of glucose. Water also creates a chemical potential across the cell membrane that results in the synthesis of ATP molecules that are required to provide energy to the plants.
Why water is needed for photosynthesis?
Plants also need water for photosynthesis. Photosynthesis is what plants do to create their food, and water is critical to this process. The water from the leaves evaporates through the stomata, and carbon dioxide enters the stomata, taking the water’s place. Plants need this carbon dioxide to make food.
Does photosynthesis work in water?
Aquatic Plants and Photosynthesis Plants, including aquatic plants, produce oxygen, and they also use oxygen. Here’s how these processes work: During a sunny day, dissolved oxygen in water is generally plentiful because photosynthesizing algae and aquatic plants are constantly releasing it into the water.
How much h2o is used in photosynthesis?
Overall equation for photosynthesis 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation.
Why is 12 H2O used in photosynthesis?
12molecules of h2o used as substrate because in 12h2o there are 24 atoms of hydrogen and it has to split to form12 atoms of hydrogen in sugar and 12 atoms in water.
How does water help photosynthesis?
Explanation: Water is one of the reactants in photosynthesis, it provides the hydrogen needed to form glucose (a hydrocarbon). Water and carbon dioxide enter the leaf through the stomata (small holes on the underside of the leaf that are controlled by gaurd cells) by diffusion.
How does water affect the rate of photosynthesis in plants?
Water affects the rate of photosynthesis indirectly. Water stress causes the stomata to close and thereby reduces carbon dioxide availability. Water stress also results in wilting of leaves and therefore reduces metabolic activity performed by leaves.
Does water affect the rate of photosynthesis in plant?
How does water affect the rate of photosynthesis in plants? Answer: Water controls the opening and closing of stomata. Therefore, G02 (required as a raw material for photosynthesis) cannot enter into the leaves and thus lack of water slows down the rate of photosynthesis.
Does increasing water increase photosynthesis?
Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis , until some other factor – a limiting factor – becomes in short supply.
