Plants are grown for pleasure in gardens and greenhouses, yielding flowers, shade, and decorative foliage; some, such as cactuses, able to tolerate dry conditions, are grown as houseplants. Animals such as horses and deer are among the earliest subjects of art, being found in the Upper Paleolithic cave paintings such as at Lascaux. Living ...
Rotary International is an international service organization based in Evanston, Illinois, US. Members of Rotary clubs are called "Rotarians."
The classification of living things into animals and plants is an ancient one. Aristotle (384–322 BC) classified animal species in his History of Animals, while his pupil Theophrastus (c. 371 –c. 287 BC) wrote a parallel work, the Historia Plantarum, on plants. [7]
Plant-animal interactions are important pathways for the transfer of energy within ecosystems, where both advantageous and unfavorable interactions support ecosystem health. [ 1 ] [ 2 ] Plant-animal interactions can take on important ecological functions and manifest in a variety of combinations of favorable and unfavorable associations, for ...
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).
In the 1940s, when Taylor was an international director of Rotary, he offered the Four Way Test to the organization, and it was adopted by Rotary for its internal and promotional use. Never changed, the twenty-four-word test remains today a central part of the permanent Rotary structure throughout the world, and is held as the standard by which ...
The plant Arabidopsis thaliana is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. [25] NASA predicts that space stations or space colonies will one day rely on plants for life support. [26] Scientific advances in genetic engineering led to developments in crops.
Cooperation exists not only in humans but in other animals as well. The diversity of taxa that exhibits cooperation is quite large, ranging from zebra herds to pied babblers to African elephants. Many animal and plant species cooperate with both members of their own species and with members of other species.
