Photosynthesis is the chemical process used by plants (and a few other organisms) to convert sunlight, water, and air into the energy needed for the plant to grow and survive. Learn more with today’s crop of website picks.

"If you're not a microbe and you're not an animal, chances are you are a plant. There are loads of species of plants on Earth. Just as there is a system of classification for animals, there is also a system of classification for plants." This Biology4Kids introduction to plants is divided into ten parts. Start your tour with Photosynthesis and progress by using the navigation buttons at the bottom of each page, or jump to any section via the menu at the top of the right-hand column.
For high-school students, Pearson offers nine interactive animations (covering eight concepts) and a twenty-five question multiple-choice quiz. "The animations review the important characteristics of light energy, quiz your recall of leaf and plant cell anatomy, demonstrate the general process of photosynthesis, and examine the molecular events that take place in the chloroplast."

"Photosynthesis is one of the coolest processes that scientists know about!" Okay, that line made me laugh, but this StudyJames cartoon from Scholastic does do a good job of introducing photosynthesis to elementary age students. When you're done with this one, just click on Science for related StudyJam cartoon videos including Plant Cells, Roots & Stems, Flowers and Plant Adaptations.
"Photosynthesis in plants and a few bacteria is responsible for feeding nearly all life on Earth. It allows energy from the sun to be converted into a storable form, usually glucose, which plants use to grow and thrive." This photosynthesis lesson is available in both interactive and printable form. For high-school students, PBS does a great job of explaining the chemistry of photosynthesis, and includes three Puzzles to ponder and discuss.
Wiley illustrates the basics of photosynthesis in five slides. Navigate through them by clicking the titles on the green leaves, or use the nav buttons at the bottom of the slides. "Ultimately, all the energy required to sustain life on Earth comes from the sun. Plants, and some bacteria, absorb solar energy and harness it to produce their own fuel and biosynthetic molecules."
