What are the steps in photosynthesis?
The stages of photosynthesis
| Stage | Location | Events |
|---|---|---|
| Light-dependent reactions | Thylakoid membrane | Light energy is captured by chloroplasts and stored as ATP |
| Calvin cycle | Stroma | ATP is used to create sugars that the plant will use to grow and live |
What is photosynthesis 7th grade definition?
photosynthesis. the process by which plants and some other organisms capture the enegry in sunlight and use it to make food. heterotroph. an organism that cannot make its own food.
What are sites of photosynthesis?
Photosynthesis takes place in special organelles known as chloroplast. This organelle has its own DNA, genes and hence can synthesize its own proteins. Chloroplasts consist of stroma, fluid, and stack of thylakoids known as grana.
Which are the main site of photosynthesis in plant?
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 are the reactants and products of photosynthesis?
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants ( Figure 5.5 ). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
What are the main structures involved in photosynthesis?
Describe the main structures involved in photosynthesis All living organisms on earth consist of one or more cells. Each cell runs on the chemical energy found mainly in carbohydrate molecules (food), and the majority of these molecules are produced by one process: photosynthesis.
How do you summarize the complex reactions of photosynthesis?
The complex reactions of photosynthesis can be summarized by the chemical equation shown in Figure 5.6. Figure 5.6 The process of photosynthesis can be represented by an equation, wherein carbon dioxide and water produce sugar and oxygen using energy from sunlight.
What is the source of energy in photosynthesis?
These sugar molecules contain energy and the energized carbon that all living things need to survive. Photosynthesis uses solar energy, carbon dioxide, and water to produce energy-storing carbohydrates. Oxygen is generated as a waste product of photosynthesis. The following is the chemical equation for photosynthesis ( [link] ):
