PLANTS absorb light for photosynthesis but as light can itself be dangerous to plants, they need to protect themselves against its damaging effects. Here we show that photorespiration can act as such a defence mechanism. We constructed transgenic tobacco plants enriched or reduced in plastidic ...
Plants absorb light energy for photosynthesis via photosystem complexes in their chloroplasts. However, excess light can damage the photosystems and decrease photosynthetic output, thereby inhibiting plant growth and development. Plants have developed a series of light acclimation strategies that allow them ...
During photosynthesis, carbon dioxide enters the stomata. The root hairs absorb the water from the soil and carry it to the leaves through the xylem vessels. Chlorophyll absorbs light energy from the sun and splits water molecules into hydrogen and oxygen. The carbon dioxide from the air and h...
Plants need sunlight to carry out photosynthesis. Which part of a plant mainly absorbs sunlight? A. Root B. Stem C. Leaf D. Flower 相关知识点: 试题来源: 解析 C。解析:植物的叶子主要进行光合作用,在光合作用中吸收阳光。根主要功能是吸收水分和矿物质,茎起到支撑和运输的作用,花主要用于繁殖,所以...
One of the most important processes that plants carry out is photosynthesis. Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. During photosynthesis, plants absorb sunlight through their leaves. The chlorophyll in the leaves captures ...
The leaves absorb the carbon dioxide and water vapor that, with the help of light energy, are converted to carbohydrates, and aid the release of energy in atmosphere by the plant by taking in oxygen for respiration. During photosynthesis, the absorbed carbon dioxide and the energy from sunlight...
Leaves are the main site for photosynthesis. Leaves contain chloroplasts, which are the organelles in plant cells where photosynthesis occurs. Chloroplasts contain molecules of chlorophyll that absorb visible light, mainly in red and blue wavelengths. Only a few molecules of chlorophyll absorb green wav...
Plants produce oxygen as a by-product of photosynthesis, which is then released into the atmosphere. This oxygen is essential for the survival of all aerobic organisms, including humans. Photosynthesis also helps regulate the Earth's climate. Plants absorb carbon dioxide from the atmosphere during ...

limiting the size of the genome,which is contained within the nucleus(细胞核)of the cell ,plants can build smaller cells.In turn ,this allows plants to absorb more carbon dioxide from photosynthesis—the process by which plants use light energy to turn carbon dioxide and water into sugar and...
