HOW DOES THE PLANT OBTAIN CARBON DIOXIDE AND WATER FOR PHOTOSYNTHESIS

Photo means ‘light’ and synthesis means ‘to build’ thus photosynthesis means’ building up light’. The plant uses energy in the sunlight to prepare food from carbon dioxide and water in the presence of chlorophyll.

So, in this article we will be discussing some facts about plants and animals and figure out, how does photosynthesis and cellular respiration works together to maintain the balance of nature or life.

Photosynthesis is a physio-chemical process by which green plants and certain other Organism synthesize carbohydrates in the presence of light by utilizing CO2 and H2O or it is an anabolic reductive and an endergonic process that uses light energy to photochemically reduce CO2 into carbohydrate O2 is the byproduct.

There are a large number of tiny pores called stomata on the surface of the leaves of plants.

The green plants take carbon dioxide from the air for photosynthesis. Each stomatal pore is surrounded by a pair of guard cells. The opening and closing of the stomatal pore are surrounded by a pair of guard cells.

When water flows into the guard cells, they swell, become curved, and cause the pore to open. On the other hand, when the guards will lose water, they shrink become straight and closed the stomatal pores.

The oxygen gas produced during photosynthesis goes out through the stomatal pores of leaves.

The water required by the plant for photosynthesis is absorbed by the roots of a plant from the soil through the process of osmosis. The water absorbed by the roots of the plants is transported upward through the xylem vessels to the leaves, where it reaches the photosynthetic cells and is utilized in photosynthesis.

The two raw materials carbon dioxide and water are required by the plants to prepare energy food called carbohydrates (such as glucose and starch )but the plants also need other raw materials such as nitrogen, phosphorus, iron, magnesium, etc. for building their body. The plants take materials like nitrogen, phosphorus, iron, magnesium, etc. from the soil.

HOW DOES CELLULAR RESPIRATION WORK

Cellular respiration is one such biochemical process via which ATP or adenosine triphosphate is produced which is basically a form of energy that is being useful in carrying out the essential process of life forms.

So, cellular respiration mainly happens to see in heterotrophs or such organisms which can’t have the ability to prepare their own food so they are in need to depend on other beings in order to gain glucose.

The important chain of content which are helpful in the production of ATP are glycolysis, citric acid cycle pyruvate oxidation, and oxidative phosphorylation.

Generally, cellular respiration involves two sub different type of process namely catabolism and anabolism, both of the process plays a vital role in obtaining the chemical compound from the breaking down of glucose. 

It is a catabolic process that is really helpful in squeezing down the larger molecular compound of sugar into the tiniest form of it with the release of energy.

Cellular respiration is a combustion reaction in some way or up to some extent as it releases heat with a series of molecular reactions. Moreover, cellular respiration has been divided into two subtypes, aerobic respiration, and anaerobic respiration.

 Aerobic respiration takes place when the cell releases carbon dioxide with the absorption of a molecular compound of oxygen whereas, when the cells consume other molecular compounds as their inputs other than the oxygen, it is then the anaerobic process comes in place.

The usage of biochemical energy for prokaryotic and eukaryotic cells is very important, as it helps in various metabolic processes of cells.

How are photosynthesis and cellular respiration related to each other

Photosynthesis and cellular respiration are complementary processes. Photosynthesis is a photochemical process where plants can capture and fix the energy of the sun. The chemical reaction of photosynthesis is as follows

6CO2 + 12H20 ——-> C6H12O6 + 6H20 + 6O2

 Respiration is a typical process where mitochondria of cells release chemical energy from sugar and other organic molecules through chemical oxidation. This process occurs in both plants and animals.

In most organisms, respiration release the energy required for all the metabolic processes.

C6H12O6 + 6CO2 ——> 6CO2 + 6H2O

Through the process of photosynthesis, green plants absorb solar energy and take carbon dioxide from the atmosphere to produce carbohydrates (Sugar) and Plant uses these carbohydrates through the process of cellular respiration which releases the energy-containing carbohydrate for various body functions.

Both the process i.e. photosynthesis and cellular respiration are completely opposite of each other as the reactant of one process is the product of another process and vice-versa. In other words, the output of one process works as the input of the other process and in reverse order too.

Photosynthesis absorbs water, carbon dioxide, and solar energy which will be then converted into glucose and oxygen. On the other hand, cellular respiration makes use of molecules of oxygen and glucose which further gave rise to water and carbon dioxide.

Plants do retain energy through both the process of photosynthesis and cellular respiration but the method of obtaining energy differs. Even, the chemical reaction equation of both photosynthesis and cellular respiration varies as per the consistency of different components of energy.

On this earth, each and every single living organism such as plants, animals and human being depends upon the components that we get through the processes of photosynthesis and cellular respiration.  This whole vicious circle of life revolves around these molecular compounds such as Oxygen, Carbon dioxide, ATP, Glucose, and water which are obtained from the biochemical process of photosynthesis and cellular respiration, and without them, we cannot take a single breath on this earth.

Moreover, there are movements of electrons that are being seen in the processes of photosynthesis and cellular respiration as in photosynthesis, electrons go in the direction from oxygen to glucose, begin in H20, and end up in the molecules of glucose. Whereas, in cellular respiration; flows in reverse direction while releasing energy with the formation of water.
