The Effect of Infrared Light on Plant Growth
Exposing the plant to ordinary red light reversed this effect. A combination of far red and red light produced the longest internodes. Plants grown in light that is too red may seem spindly and long-stemmed. Damage. Too much infrared light, especially in the far red end of the spectrum, may actually damage plants. Heat may discolor or kill ...

Lesson 4: Radiation Detection and Attenuation with Geiger Counter
It operates based on the ionization effect produced by radiation when it interacts with matter. The core of a Geiger counter is the GM tube, which is filled with an inert gas, often argon or neon. When ionizing radiation, such as alpha, beta, or gamma particles, passes through the GM tube, it collides with the atoms of the gas within the tube.

The fragrance of plants: how their perfume pervades the air
Plants are sessile organisms, which means that they do not move. In order to respond to environmental stresses and to interact with other organisms, plants instead rely on a chemical language. Volatiles, small compounds that are responsible for the characteristic smells of plants, are one of the key players in plant communication.

Is it useful to ask why plants emit isoprene?
The likelihood of gain or loss of function is taken to be nearly equal. Monson et al.() decided ties in favour of loss of function, but otherwise assumed that the fewest changes of state (emitting or non‐emitting) that explains the tree was correctThe assumption that gain or loss of function should be treated as equivalent can be explained by the fact that once a new genetic …

Methane Emissions? Don't Blame Plants | Science | AAAS
Plants do not make the powerful greenhouse gas methane, according to new research that contradicts a controversial finding made in 2006. Instead, plants appear to merely be passing gas, so to speak, originally made by soil microbes. Methane comes from a variety of sources, including gas leaks, forest fires, and, of course, cow burps.
