Photosynthesis - Education | National Geographic Society
2024年6月21日 · Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Photosynthesis - Education | National Geographic Society
Photosynthesis Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
Sweet Secret - Education
Creating G3P is the ultimate objective of the Calvin cycle. In step three, some of the G3P molecules are used to create sugar. Glucose, the type of sugar produced by photosynthesis, is composed of two G3P molecules.
The Carbon Cycle - Education
2023年10月19日 · It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs. The movement of carbon from reservoir to reservoir is known as the carbon cycle.

2023年10月19日 · Photosynthesis. Photosynthesis. Learn about the process that plants, algae, and some bacteria use to make their own food and the oxygen we breathe. Grades. 5 - 12. Subjects.
Chlorophyll - Education | National Geographic Society
2023年10月31日 · Chlorophyll is a key component in the process of photosynthesis, which sustains plant life and produces oxygen for the entire planet. Although microscopic in size, chloroplasts like these have a big role to play in the health of the planet.
Carbon Sources and Sinks - Education
2023年10月19日 · The carbon cycle describes the flow of carbon between each of these places. For example, carbon continually flows in and out of the atmosphere and also living things. As plants photosynthesize, they absorb carbon dioxide from the atmosphere.
Water Cycle - National Geographic Society
2024年4月29日 · Earth’s water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans. The rain came from water vapor that escaped the magma in Earth’s molten core into the atmosphere.
Biomass Energy - Education | National Geographic Society
2023年10月19日 · Biomass contains energy first derived from the sun: Plants absorb the sun’s energy through photosynthesis, and convert carbon dioxide and water into nutrients (carbohydrates). The energy from these organisms can be transformed into usable energy through direct and indirect means.
Cellular Respiration - National Geographic Society
2023年10月19日 · Cellular respiration is the process by which food, in the form of sugar (glucose), is transformed into energy within cells.
