In plants, photosynthesis takes place in chloroplasts, which contain chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane called the thylakoid membrane, which forms long folds within the organelle.
What is Photosynthesis?
Most living things depend on photosynthetic cells to make the complex organic molecules they need for energy. Photosynthetic cells are very diverse and include cells found in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and solar energy to make sugar molecules and oxygen.
These sugar molecules are the basis for more complex molecules produced by the photosynthetic cell, such as B. Glucose. Then the cells synthesize high-energy carrier molecules such as ATP from oxygen and glucose in respiration processes, and carbon dioxide is produced as a waste product. Therefore, the synthesis of glucose and its breakdown by cells are opposite processes.
The building and breaking down of carbon-based material, from carbon dioxide to complex organic molecules (photosynthesis) and then back to carbon dioxide (respiration), is part of what is commonly referred to as the global carbon cycle.
In fact, the fossil fuels we use today to power our world are the ancient remains of organisms that once lived, providing a dramatic example of this cycle.
