Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem bends to the side of the slower growing cells as a result.
The dogwood bunchberry's flower opens its petals and fires pollen in less than 0.5 milliseconds. The record is currently held by the white mulberry tree, with flower movement taking 25 microseconds, as pollen is catapulted from the stamens at velocities in excess of half the speed of sound—near the theoretical physical limits for movements in ...
For some, cilantro tastes like soap, dirt, crushed bugs or metal shavings.
Available in a wide variety of colors, begonia plants are great for beginner gardeners to grow. These tiny flowers prefer filtered light or partial shade as all-day, direct sunlight can cause the ...
Forcing is the horticultural practice of bringing a cultivated plant into active growth outside of its natural growing season. Plants do not produce new growth or flowers (and hence fruit) during the winter, and many species only produce flowers or fruit for a very limited period.
Cilantro: Cilantro is a source of antioxidant flavonoids, vitamin A, vitamin K, folate, and potassium, says Matey. It has many benefits for the body, as it can help lower blood sugar and reduce ...
It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. [1] Nyctinasty is found in a range of plant species and across xeric , mesic , and aquatic environments, suggesting that this singular behavior may serve a variety of ...
