Researchers studied how plants search for water when soil becomes dry. Plants normally grow roots downward due to gravity.

Fine roots are the most permeable portion of a root system, and are thought to have the greatest ability to absorb water, particularly in herbaceous (i.e., non-woody) plants (McCully 1999).

Third, the roots will absorb water more quickly instead of just sitting in soggy soil, which can lead to root rot. If your plants are wilting and stressed, you may decide to water in the evening ...

Roots "feel" gravity to extend and anchor themselves in the soil, but they can alter their growth direction toward a water source when needed. However, according to a new study by scientists at the ...

Root hair cells don't have light absorbing chloroplast because they don't absorb light because they're underground. What they do have is a wide surface area to more efficiently absorb water and ...
