What is the chemical formula for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is the structure of photosynthesis?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
What is first step in photosynthesis?
When chlorophyll absorbs light, it gets excited and emits electrons. These electrons are picked up by an electron acceptor which passes them to an electron transport system of cytochromes. The excitement of electrons of chlorophyll b photon of light is the first step of photosynthesis.
How many steps are in photosynthesis?
What are the main events of photosynthesis?
The three major events that occur during the process of photosynthesis are: > Absorption of light energy by chlorophyll. > Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
What are the two main events of photosynthesis?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
What are the three main events of photosynthesis?
Following are the three important events that occur in the process of photosynthesis:
- Absorption of light energy by chlorophyll:
- Conversion of energy: Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
What are the raw materials of photosynthesis?
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
What are the raw materials for photosynthesis Class 7?
The raw materials for photosynthesis are as follows:
- Carbon dioxide – through gaseous exchange carried out by stomata.
- Water – roots absorb water from the soil provided by irrigation or even rains.
- Sunlight – chlorophyll, the green pigment present in green plants traps solar energy.
Which of these is not a raw material for photosynthesis?
How many water molecules are used in photosynthesis?
6 water water molecules
Where does the water come from in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.
Which part of the plant performs photosynthesis?
Which part of plant is most important for photosynthesis?
What type of cell performs photosynthesis?
In what cells does a majority of photosynthesis occur?
You should notice that the vast majority of chloroplasts are found in the cells of the mesophyll. Even more specifically, the palisade layer has the most chloroplasts, so the greatest amount of photosynthesis occurs in that leaf layer.
What are the photosynthesis products?
Let’s look at the products of photosynthesis! During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
What is the end product of photosynthesis?
Glucose and oxygen are the final products of photosynthesis.
What is the difference between photosynthesis and cellular respiration in plants?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
Is ribosomes plant or animal cell?
Ribosomes are either located in the liquid inside the cell called the cytoplasm or attached to the membrane. They can be found in both prokaryote (bacteria) and eukaryote (animals and plants) cells. Ribosomes are a type of organelle. Organelles are structures that perform specific functions for the cell.
