Recent Examples of photosynthesis from the Web
Drones and satellites provide infrared and thermal imagery that measure the photosynthesis rates of crops.
Six-part series includes topics on: the cell and structure of a plant, mineral nutrition and photosynthesis, respiration and metabolism, inorganic nutrients and hormones, plant babies, cell death, biotic and abiotic stress.
Light is essential to photosynthesis, which is how plants feed themselves.
Today, researchers there are working on a new treatment for brain cancer, a way to boost photosynthesis to increase crop yields, and a solution to the growing problem of antibiotic resistance.
Additionally, capacitance jumped up and down over the 24-hour light cycles, suggesting that capacitance can also detect photosynthesis.
To keep the artificial photosynthesis reaction going at low energies, the Berkeley team turned to a variety of new materials.
On Earth, photosynthesis is based on pigments like chlorophyll, which absorbs blue and red light and appears green to human eyes.
Ecologists believe red pigments in deciduous trees act as sunscreen, antioxidants and antifreeze so the trees can hold on to dying leaves longer while absorbing more of the nutrients produced by photosynthesis.

photosynthesis Has Greek Roots
The Greek roots of photosynthesis combine to produce the basic meaning "to put together with the help of light". Photosynthesis is what first produced oxygen in the atmosphere billions of years ago, and it's still what keeps it there. Sunlight splits the water molecules (made of hydrogen and oxygen) held in a plant's leaves and releases the oxygen in them into the air. The leftover hydrogen combines with carbon dioxide to produce carbohydrates, which the plant uses as food—as do any animals or humans who might eat the plant.
