The Power of Movement in Plants

Autor Charles Darwin
en Limba Engleză Paperback
In this 1880 book, written with his son Francis, Darwin makes the pioneering attempt to connect plant movements with the larger scheme of biological behavior. Not well received at the time, it has proven to be an enduring influence on plant movement research: he was talking about Phototropism, that plants grow towards a light source.

Descriere

Descriere de la o altă ediție sau format:

Written in collaboration with his son Francis, a notable botanist, this 1880 book builds on Darwin's earlier investigations into climbing plants, orchids, insectivorous plants, flower variety, and the processes of fertilisation. This detailed study of many species from seed to mature plant further develops Darwin's work on adaptation and evolution, with the aim of collating the results of individual studies into common factors applicable to plants in general. Particular emphasis is given to analysis and investigation of the process here termed circumnutation, the movement of the stem of the plant in order to direct the head in certain directions. This is seen as of paramount importance, with the conclusion that it is modification of this feature that has enabled plants to adapt and evolve so diversely. The authors also note similarities between plants and animals, such as sensitivity to touch and habit of action at certain times.


Notă biografică

Charles Robert Darwin (1809-1882) was born in Shropshire, England. His first text chronicling his five-year voyage on the HMS Beagle, which included his notable visit to the Galapagos Islands, earned him success as an author in 1839. His observations from the Galapagos, alongside an interest in natural history from an early age and studies over the consequent years, informed the development of his biological theories, culminating the ground-breaking text 'On the Origin of Species' for which he is best known.
