Light as an Energy SourcePlants that are able to create energy fromsunlight are known as photoautotrophs. Theterm is Greek and means "placing with light."Not all plants can produce energy fromsunlight. Such plants are calledchemoautotrophs; they instead draw energyfrom inorganic compounds in the soil. Theprocess by which plants turn light into energyis called photosynthesis. Many of the basicsteps to photosynthesis were discovered asearly as the 1600s by scientists throughoutmuch of Europe, but the specifics of the entireprocess have yet to be completely discoveredor defined.Read more: How Do Plants Get Energy From Su
• • There are approximately 250,000 different types of flowering plants in the world.• • Wheat is the world’s most widely cultivated plant. It is grown on every continent except Antarctica.• • One ragweed plant can release as many as one billion grains of pollen.• • Sunflowers have long been used to control weeds in cultivated fields. They produce a natural toxin• from their roots that keeps weeds from germinating.• • There are almost 600 species of carnivorous plants. They capture and kill prey like small insects and• then digest and absorb the nutrients. Most carnivorous plants capture insects, but some species can• capture frogs, birds, and even small rodents!
