What are the steps of photosynthesis Khan Academy?
The stages of photosynthesis
| Stage | Location | Requires sunlight? |
|---|---|---|
| Light-dependent reactions | Thylakoid membrane | Yes |
| Calvin cycle | Stroma | No |
What are the two main stages of photosynthesis?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
How do plants eat?
Plants don’t eat food. They use the energy from the sun, or other light and use it to make their food. The ingredients for this process are water, air, and light. Plants don’t use all the parts of the air, they only use the carbon dioxide (CO2) to make their food.
Do plants drink?
Plants drink water through a process called osmosis. Osmosis is the movement of a liquid into a living thing, creating a balance of that liquid. The plant will draw the colored water up and some of the color molecules will stay in the upper parts of the plant, coloring the top of the stalks or flowers!
What is the equation for the process of photosynthesis?
Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2. During this process, organisms such as plants go through the light-dependent and light-independent reactions to convert carbon dioxide and water into sugars and oxygen.
Where does photosynthesis take place in the leaf?
Photosynthesis in the leaves of plants involves many steps, but it can be divided into two stages: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy.
How are light dependent reactions used in photosynthesis?
The light-dependent reactions Get 3 of 4 questions to level up! In the Calvin cycle, energy storage molecules from the light-dependent reactions are used to capture (fix) carbon dioxide molecules and build sugars. Learn more about how this important cycle works.
How is solar energy used in photosynthesis process?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.
