Many plants lose much of the remaining energy on growing roots. Most crop plants store ~0.25% to 0.5% of the sunlight in the product (corn kernels, potato starch, etc.). Photosynthesis increases linearly with light intensity at low intensity, but at higher intensity this is no longer the case (see Photosynthesis-irradiance curve). Above about ...
Plants adapted to shade have the ability to use far-red light (about 730 nm) more effectively than plants adapted to full sunlight. Most red light gets absorbed by the shade-intolerant canopy plants, but more of the far-red light penetrates the canopy, reaching the understorey. The shade-tolerant plants found here are capable of photosynthesis ...
ShutterstockCast your mind back to your fifth grade biology class when you first learned about photosynthesis, the process where plants use energy from sunlight to convert carbon dioxide and water ...
Most vegetables are full-sun plants that require at least 8 hours of direct light to grow outdoors; however, plants like tomatoes generally need 16-18 hours of bright light to fruit inside.

Each gram molecule of condensing water will bring about a marked 1200-fold plus reduction in volume.The simultaneous release of latent heat will drive air from below to fill the partial vacuum. The energy required for the surrounding air to move in is readily calculated from the small (one-fifteenth of latent heat) reduction in temperature.
He found that plants in less-pure water sources grew better than plants in distilled water. By 1842, a list of nine elements believed to be essential for plant growth had been compiled, and the discoveries of German botanists Julius von Sachs and Wilhelm Knop , in the years 1859–1875, resulted in a development of the technique of soilless ...
If the water potential in the ambient air is lower than that in the leaf airspace of the stomatal pore, water vapor will travel down the gradient and move from the leaf airspace to the atmosphere. This movement lowers the water potential in the leaf airspace and causes evaporation of liquid water from the mesophyll cell walls.
