Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
The inclined asymptote has a positive slope representing the efficiency of light use, and is called quantum efficiency; the x-intercept is the light intensity at which biochemical assimilation (gross assimilation) balances leaf respiration so that the net CO 2 exchange of the leaf is zero, called light compensation point; and a horizontal ...
Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Negative phototropism is not to be confused with skototropism, which is defined as the growth towards darkness, whereas negative phototropism can refer to either the growth away from a light source or towards the darkness ...
Plants that are able to rapidly move their leaves or their leaflets in response to mechanical stimulation such as touch (thigmonasty): Mimosa pudica leaves closing after being touched Timelapse video of rotating Codariocalyx motorius leaflets. Aeschynomene: Large leaf sensitive plant (Aeschynomene fluitans) Aeschynomene americana [7]
The amount of energy transferred from potential to kinetic during pendulum-like movement is known as energy recovery. [8] Maintaining a higher energy recovery during brachiation costs less energy and allows the animal to move to its destination quickly, however, this type of movement is also harder to control. [8]

All cells can be considered motile for having the ability to divide into two new daughter cells. [1] Motility is the ability of an organism to move independently using metabolic energy. This biological concept encompasses movement at various levels, from whole organisms to cells and subcellular components.
