photosynthesis
It's the process by green plants and organisms use sunlight to synthesize foods from carbon dioxide and water.

Cellular respiration
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules.
What is cellular respiration?
The metabolic processes whereby certain organisms obtain energy from organic molecules.

Carbon dioxide
This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water, hence the name photosynthesis, from the light, and synthesis, putting together.

Oxygen
Photosynthesis
is a process used by plants and other organisms to convert light energy, normally from the sun, into chemical energy that can be later released to fuel the organisms' activities.

Glucose
Glucose is made up of carbon, hydrogen and oxygen atoms. Glucose made by the process of photosynthesis may be used in three ways:
It can be converted into chemicals required for growth of plant cells such as cellulose
It can be converted into starch, a storage molecule, that can be converted back to glucose when the plant requires it
It can be broken down during the process of respiration, releasing energy stored in the glucose molecules

Sunlight
Sunlight is an important part of photosynthesis. This is because Photosynthesis is when a plant turns the energy that it gets from the Sun into energy that the plant can use. When a plant has more sunlight it can photosynthesize faster because there is more sunlight for the plant to convert into energy. It is also important because it provides the energy that causes water and carbon dioxide to react. basically sunlight to a plant is like water and oxygen to us. hope this helps!

Water
Plants use a complex chemical reaction called photosynthesis to create food from light energy, carbon dioxide from the atmosphere, and water. Each of these performs a critical portion of the photosynthesis process, dependent on the others. While light energy can be easily absorbed from the sun and carbon dioxide from the atmosphere, water is sometimes scarce. Not only is water used directly in the process of photosynthesis for its hydrogen, it is also used to prevent dehydration, indirectly supporting the successful creation of food for the plant.

ATP
ATP stands for adenosine triphosphate, which is a compound that a cell uses to store energy. In plant photosynthesis, the plant takes in carbon dioxide as well as sunlight and releases oxygen. ATP plays a role in making the proper conversion so the plant can use the energy.

Chloroplast
Chloroplasts are organelles, specialized subunits, in plant and algal cells. Their main role is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, and stores it in the energy storage molecules ATP and NADPH while freeing oxygen from water. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants.

Chlorophyll
The chlorophyll is found in the thylakoid membrane. chlorophyll is the pigment that absorbs in red and blue and reflects green, which makes plants look green. chlorophyll captures the sun's energy and is used as energy to complete the photosynthesis process (light dependent reaction.)

Mitochondria
basically, there is a series of proteins on the membrane, which are called electron carriers. these are arranged such that each subsequent membrane is less electronegative than the preceding one. electrons are then supplied to the first electron carrier, which will pass the electrons down the second electron carrier, and so on. energy will be released due to the decreasing electronegativity of each carrier, and these energy is used to pump protons across the membrane to generate a proton-motive force. at the end of the electron transport chain, there is a proteins called the ATP synthase or stalk particle, which allows protons to diffuse through in the opposite direction it was pumped earlier on. as a result, ADP is phosphorylated to ATP, generating energy.

Stomata
Stomata are small openings on the underlining of the leaf. They allow co2 to enter the leaf and allow for oxygen to escape. They also play a part in transpiration allowing water to escape the leaf causing water to move through the xylem and replacing the lost water from the leaf providing water for photosynthesis
