This process is extremely important for life on earth as it provides the oxygen that all other life depends on.
Just like humans and other living things, plants also need this food for many things. Let's see a few:
Glucose resulting from photosynthesis is used during respiration to release energy that the plant needs for other life processes.
The plant cells also convert some of the glucose into starch for storage. This can then be used when the plant needs them. This is why dead plants are used as biomass, because they have stored chemical energy in them)
Glucose is also needed to make other chemicals such as proteins, fats and plant sugars that are all needed for the plant to carry out essential growth and other life processes.
Plant roots normally take up water by osmosis—by having more dissolved material within the cells of the roots than outside, causing the water to diffuse into the roots. In situations where there is too much dissolved material (such as salts) in the soil, a plant can die from lack of water even when in moist soil. The beds of playa lakes often present this situation, leaving them entirely free of plant life or with small numbers of plants especially adapted for such conditions.

Many desert plants have solved the problem to a degree. A number of them use that quickly capture carbon dioxide, allowing the stomata to be closed more often than in plants not adapted for this. These so-called C4 plants (as opposed to C3 plants without the adaptation) also do much better in strong light and hot temperatures. C3 plants under such conditions tend to burn more carbohydrates than they manufacture. Many warm-climate grasses and such things as four-wing saltbush are C4 plants. Cacti and many succulents (such as the century plants, or agaves) utilize a different physiological strategy call photosynthesis. The stomata generally are opened at night, when temperatures tend to be cooler and relative humidity higher, and the carbon dioxide stored in the form of an acid; during the day, the stomata are closed and photosynthesis uses the stored carbon dioxide. CAM plants also can go into a slowed mode for extended periods of time during particularly hot, dry periods by closing the stomata and utilizing carbon dioxide from cellular respiration to manufacture food and burning food to supply energy for respiration. This makes some sense if you know that plants, like animals, produce carbon dioxide as a waste product when breaking down food stuffs to produce usable energy. Of course, energy is lost at each such cycle and eventually the process runs down.

The most serious problem most plants have in the desert environment is associated with water: how to get it and, particularly important, how to keep it. Roots have the dual functions of bringing water and dissolved minerals from the soil into the plant body to be distributed as needed. There are two major root types: tap and fibrous. Tap roots consist of a main root with branch roots coming off of it; tap roots tend to grow deep into the soil. A carrot is an example of a tap root, though most of the side branches are removed before sale and it's relatively short and fat compared to most tap roots. Fibrous roots consist of a number of roots of which the main ones are more or less the same size; fibrous roots tend to spread out relatively near the surface of the soil. Grasses generally have fibrous root systems. Some desert plants have a double system, one set of roots near the surface and another that delves deeper; creosotebush is an example.
How do Proteins Help Chlorophyll Carry out Photosynthesis?
Both, Photosystem I and Photosystem II work in tandem, without which the plant will not be able to produce ATP energy molecules and carry out other biosynthetic reactions for its survival.
What Do Plants Need to Carry Out Photosynthesis?
The roots of a plant also need oxygen which they obtain from the air spaces in the soil. If you give too much water to a plant in a pot you could kill the roots by drowning them! Plants, such as rice, which normally grow in wet soil often have air spaces in their roots. This is so that they can carry air from the atmosphere down to the root tips to be able to respire under water.
