Photosynthesis converts light energy from the sun into chemical energy stored in organic compounds, which are used to build the cells of producers and ultimately fuel ecosystems. After providing an overview of photosynthesis, a series of animations describe the inside of the cells of a leaf to explain how the reactions of photosynthesis happen.

Part of the "Visualizing Cell Processes" series. Includes the following modules on photosynthesis: "Chloroplast Structure," "Light Trapping by Chlorophyll," "Light–Dependent Reactions of Photosynthesis," and "The Light–Independent Reactions of Photosynthesis." Includes the following modules on cellular respiration: "Glycolysis and Fermentation," "Mitochondrion Structure," "Aerobic Respiration," "Krebs Cycle," "Electron Transport Chain," and "ATP synthesis."
Trees, plants, algae, and phytoplankton all do it. Learn about photosynthesis, the process that powers the world, in this animated video.
Discusses the terminology, processes, and products related to photosynthesis. Questions bridge segments and lead to information on tropism, seed structure, and germination. Includes a review and a quiz.
Explains the scientific concepts of photosynthesis, respiration, and enzymes. Laboratory experiments demonstrate: the rate of photosynthesis in greenhouse plants; the amount of oxygen used by the body during respiration at varying speeds; and the reaction times of different enzymes.
The importance of forests cannot be underestimated. Humans depend on forests for survival, from the air they breathe to the wood they use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion, and mitigate climate change.
Part of the "Inside the Living Cell" series. Illustrates the mechanisms of photosynthesis and cellular respiration. Introduces adenosine triphosphate, or ATP, the universal energy carrier molecules that supply energy-hungry reactions. Also outlines the structure and function of chloroplasts and mitochondria, energy transforming organelles. Overviews ATP and chemical energy, mitochondria, aerobic respiration, chloroplasts, and the reactions of photosynthesis.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this clip, the Micronauts explore the process of photosynthesis. They conduct experiments using paramecium by observing the green algae cells within its body. Through their experiments, they realize the in the presence of light, the green cells generate oxygen and food molecules. Part 2 of the Microscopic Monsters Series.

Discusses how the activities and processes of cells affect our lives. Covers metabolism, diffusion, respiration, and cell growth and mitosis. Includes questions and a quiz.
Students investigate important processes including photosynthesis, reproduction, growth, and germination. They also learn how these processes relate to the structure of plants. Important terminology includes flower, pistil, stamen, pollen, pollination, and reproduction.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to produce needed energy from nutrients. These processes help keep the Earth in balance by breaking down the food that photosynthesis produces.
Part of the "Branches on the Tree of Life" series. Uses crisp graphic animation to describe the molecular-level mechanisms of photosynthesis. Examples of this critical element of plant biology include the major plant groups of mosses, liverworts, ferns, horsetails, and the seed plants (gymnosperms and flowering plants).
Students explore the smallest, but most important units of life: cells. They also gain an understanding of common cell parts through lifelike animations. Additional concepts and terminology include building blocks of life, animal cell, cell membrane, nucleus, cytoplasm, plant cell, photosynthesis, cell wall, chloroplasts, organelles, and role of cells in the body.
Can trees really combat climate change? For eons, nature has relied on photosynthesis as a means to keep carbon dioxide levels from getting out of control. This episode discusses ways trees can help solve climate change. Part of the “It’s Okay to Be Smart” series.
Some plants have leaves and some have needles, but they all need a way to absorb sunlight, nutrients, air, and water. Shares a basic overview of plant structure and the essential role plants have on earth. Defines deciduous, coniferous, photosynthesis, and capillary action. Suggests several classroom experiments.
Solar panels are becoming a familiar site in communities across the United States, but what about solar fuels? A solar fuel is produced from sunlight through artificial photosynthesis, mimicking what Mother Nature has been doing for billions of years. Many chemists and chemical engineers are working to make solar fuels a viable option in the future. Part of the National Science Foundation Series “Science Nation.”
Part of the "Branches on the Tree of Life" series. The term "algae" is a catchall for several evolutionary lines of photosynthetic organisms: dinoflagellates, red algae (plastids with chlorophyll A), diatoms, yellow-brown algae and brown algae (chlorophylls A and C), and green algae (chlorophylls A and B). Explores the diversity, structure, ecological roles, and modern classification of these primary producers.
To manipulate chemical reactions on a large scale, scientists use stoichiometry to quantify those reactions. The use of stoichiometry ensures there are the right amount of reactants and products. Without it, reactions can be incomplete, with expensive materials wasted and harmful byproducts created. Using stoichiometry, scientists are creating chemicals that take the place of petroleum in fabricating sustainable materials. At a different lab, scientists are mimicking the process of photosynthesis to convert the sun’s energy into storable chemical energy. Part of Chemistry: Challenges and Solutions Series.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. When Phoebe tries to grow a big vine for her school's production of Jack and the Beanstalk, all she ends up with is a stunted little sprout. To help out, Ms. Frizzle turns her into a real vine. But to grow tall, Phoebe needs to figure out how plants eat. To unearth the amazing ways plants make their own food, Ms. Frizzle and the kids shrink down and dig deep in a quest to root out the facts.
