Shade-tolerant plants are also usually adapted to make more use of soil nutrients than shade-intolerant plants. [2] A distinction may be made between "shade-tolerant" plants and "shade-loving" or sciophilous plants. Sciophilous plants are dependent on a degree of shading that would eventually kill most other plants, or significantly stunt their ...
Unlike indoor plants—which you can provided tailored care for in the form of temperature control, water, and sunlight adjustments—outdoor varieties are more susceptible to their environment ...
The aphotic zone (aphotic from Greek prefix ἀ-+ φῶς "without light") is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1 percent of sunlight penetrates. Above the aphotic zone is the photic zone, which consists of the euphotic zone and the disphotic zone ...
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 ...
Photoprotection is the biochemical process that helps organisms cope with molecular damage caused by sunlight.Plants and other oxygenic phototrophs have developed a suite of photoprotective mechanisms to prevent photoinhibition and oxidative stress caused by excess or fluctuating light conditions.
Humans have explored less than 4% of the ocean floor, and dozens of new species of deep sea creatures are discovered with every dive. The submarine DSV Alvin—owned by the US Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts—exemplifies the type of craft used to explore deep water. This 16 ton ...
