Through the action of sunlight and chlorophyll, they make food and oxygen in their green parts through an amazing process called photosynthesis. But plants don’t just take in carbon dioxide and ...

Rising temperatures make plants lose more water, weakening their ability to absorb carbon dioxide and survive heat stress.

and oxygen to, well, creatures like us. (To do that, trees convert carbon dioxide—too much of which can be harmful to the atmosphere—into our life-giving oxygen.) But trees are threatened by ...

So, plants harness the energy from ... Chlorophyll absorbs sunlight and uses its energy to convert carbon dioxide and water into glucose. Oxygen is also produced. Time for a demo here.

Cells get nutrients from their environment, but where do those ... in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and energy ...
