Plants are living things which react to their environment. One of the environmental factors affecting your home plants is mild. Plants growing in a place where the lighting is less than optimal can’t pick themselves up and move to a better spot, but they possess some ability to move around in place to improve the illumination where they’re. This movement is known as phototropism.
Light Is Life
Plants need light to your photosynthesis that makes it possible for them to live, so they grow in the direction where the light is strongest. Outside, daylight comes from all sides of plants so they grow straight up. Indoors, daylight comes from 1 side, through a window, therefore growing plants tend to lean toward the window to achieve the strongest sunlight.
Sensitive Cells
The plants lean because of a phenomenon known as differential growth, where the cells on the “dim” aspect of the stem grow faster than the cells on the “bright” side. The result is the plant bends toward the light source. Plants have special photoreceptive cells known as phototropins which are sensitive to blue light. These cells, located in the growing tip of the plant’s stem, detect the second difference in blue-light intensity between the bright and dim surfaces of the plant and induce differential growth in the stem which thrives the cylinder toward the bright side.
Hormonal Trigger
The light-sensitive phototropin cells manufacture a growth hormone called auxin that’s distributed evenly throughout the plant’s stem if the light strikes the plant evenly. But as soon as the light strikes the plant from only one particular direction, more auxin flows down the dim side of the stem to activate faster growth on that side. As a result, the plant bends toward the light source.
Light Plantkeeping
To promote symmetrical growth, give your home plants a quarter turn weekly. Check the plants’ overall state to ensure they’re in the ideal spot. A plant getting insufficient light will get long and spindly with slender, pale leaves; watery, weak stems; and little new growth. If the low-light condition persists, leaves eventually will yellow and drop off. A plant having too much light will come to be extremely compact, with leaves which curl under, wilt, or develop yellow or yellow patches.
