Trees need sunlight for the same reason you need food. The energy from the Sun’s rays is a crucial ingredient in how plants make their own food that helps them power all their cells. Since trees don’t ...

Plants have small pores on the underside of their leaves, known as stomata. When the sun rises, these pores open and the plants absorb carbon dioxide (CO 2) from the atmosphere, which they need, in ...

A new study finds that tree growth does not seem to be generally limited by photosynthesis but rather by cell growth. This suggests that we need to rethink the way we forecast forest growth in a ...

In a head-to-head battle of harvesting the sun's energy, solar cells beat plants. But scientists think they can even up the playing field. Plants are less efficient at capturing the energy in sunlight ...

SAN FRANCISCO (KGO) -- We know that plants and trees are important because they produce oxygen while absorbing carbon dioxide. With cell manipulation, there are early signs this benefit can be made ...

The relationship between photosynthetic capacity ($A_{\text{max}}$) and leaf nitrogen concentration (N) among all C₃ species can be described roughly with one ...

What will happen to the world’s forests in a warming world? Will increased atmospheric carbon dioxide help trees grow? Or will extremes in temperature and precipitation hold growth back? That all ...
