Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens. [1]
In one example, a plant’s flowering phenology and its seed-dispersing ant mutualist’s phenology are both triggered by temperature cues. [27] Because the plant’s phenology is more prone to change under a new climate regime than the ant’s, the plant is decoupled from the selective pressure for flowering synchrony that the ant mutualism ...
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".
Some analyses suggest that vegetative reproduction is a characteristic which makes a plant species more likely to become invasive. Since vegetative reproduction is often faster than sexual reproduction, it "quickly increases populations and may contribute to recovery following disturbance" (such as fires and floods). [16]
One of the outcomes of plant reproduction is the generation of seeds, spores, and fruits [13] that allow plants to move to new locations or new habitats. [14] Plants do not have nervous systems or any will for their actions. Even so, scientists are able to observe mechanisms that help their offspring thrive as they grow.
Rapid plant movement encompasses movement in plant structures occurring over a very short period, usually under one second. For example, the Venus flytrap closes its trap in about 100 milliseconds. [1] The traps of Utricularia are much faster, closing in about 0.5 milliseconds. [2]
The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995.. A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.
In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds. Seeds can be dispersed away from the parent ...
