What is the Difference Between Photosynthesis and Cellular Respiration?
Photosynthesis is a process that converts light energy into chemical energy of carbohydrates in the presence of sunlight and chlorophylls. Whereas, cellular respiration is a process that converts the chemical energy of organic compounds into ATP (energy currency) in order to use it for all functions occurring in living organisms. So, this is the key difference between photosynthesis and cellular respiration. Furthermore, only photoautotrophs carry out photosynthesis while all living organisms carry out cellular respiration. Hence, this is also a difference between photosynthesis and cellular respiration.
What is Photosynthesis?
Photosynthesis is a process that is carried out by photoautotrophs. Photoautotrophs produce their own food by this process. Plant, algae, and cyanobacteria are the main groups of photoautotrophs. During photosynthesis, using the light energy of sunlight, carbon dioxide, and water transform into glucose and oxygen when photosynthetic pigments are present. Oxygen, which is important to all living beings, is released to the atmosphere as a byproduct of photosynthesis. Photosynthesis is a very crucial process which allows life to continue on earth. Oxygen produced through photosynthesis is essential for the process of respiration of most living creatures on earth. Carbohydrate produced by photosynthesis is the simplest form of food that could be processed by living organisms to obtain energy.
What is Cellular Respiration?
Cellular respiration is a biochemical process by which cells convert the chemical energy of macromolecules into energy in the form of ATP. Cellular respiration uses carbohydrates, fats, and proteins as fuels. Glucose is the most commonly utilized energy source in cellular respiration. All living organisms carry out respiration: aerobic respiration in the presences of oxygen, and anaerobic respiration in the absence of oxygen. Prokaryotic cells carry out cellular respiration in the cytoplasm whereas eukaryotic cells carry out cellular respiration mostly inside the mitochondria of the cell. In aerobic respiration, one glucose molecule can generate 36-38 molecules of ATP, but in anaerobic respiration (through glycolysis and fermentation) only 2 ATP molecules could be derived.

What is the difference between light dependent and dark dependent photosynthesis?
Photosynthesis can be divided into two main processes: light dependent (light reaction) process and light independent (dark reaction) process. Light-dependent photosynthesis needs actual sunlight to react, whereas dark reaction only needs the products of the light reaction to proceed. Light reaction needs the photons and water to give out oxygen leading to the production of ATP and NADPH. NADPH is a reducing agent that can reduce its hydrogen molecule.

In the processes, the glucose is essentially broken down in order to create both water and carbon dioxide, out of the consumption of the glucose itself.
What are the factors that affect photosynthesis?
The major factors that affect the photosynthesis process are the sunlight (it needs to be there), the temperature (not too hot and not too cold, or else it will not work, since the plants can slow down at extreme temperatures), the existence of water (this is why you need to water your plants) and finally the existence of carbon dioxide, which pretty much does exist everywhere.
Why do plants need carbohydrates?
Then the plants consume their carbohydrates (sugars) which will then give them energy for normal survival things such as reproduction, growth and some is even stored to help the plant survive harsh conditions in the future, such as a harsh winter. Just like us, the plants need their energy in order to grow and to be able to survive, but they actually produce their own food.
