Why do plants need water to carry out photosynthesis?

Answer 1

Plants need to photosynthesis because this is how they make their own food, as they cant eat like we do. They use sunlight energy, water and carbon dioxide to make glucose, which is a form of food. Plants that photosynthesis contain chloroplasts, which contain the chemical chlorophyll. This traps the sunlight and is a fluid. The trapped energy is stored in the stroma. The Hydrogens from the water, H20, is combined with CO2, in the Calvin cycle, and glucose (sugar)is produced. The food is then used so that the plant can make energy so it can live and respirate.

Some plants do not photosynthesize. There are also carnivorous and parasitic plants.

Answer 2

Because water needs to be split in photosystem II so that the excited electrons that jump from the P680 chlorophyll pair into the reaction center can be replaced from the water being split. This process is called photolysis and these electrons, ultimately, supply the electron need of photosystem I, even when photosystem I preforms electron cycling.

Answer 3

The magic bit in photosynthesis is that chlorophyll is used to split the water molecule into Oxygen, as a waste gas, and Hydrogen which is used by the plant to build complex molecules.

There are specialized cells called chloroplasts which are organelles. These are considered to have developed from cyanobacteria, in a form considered as symbiotic. As such they are similar to mitochondria in animal cells, and are also concerned with ATP production. These cells are directly concerned in converting sunlight into energy.

Answer 4

photosynthesis is their food source, and they need food and/or nutrients to live.

Answer 5

So that they gain energy, and store it.
