sensitive to their environments

It was not long before Darwin compiled his observations, including those using the glass plate method, into a substantial 118-page monograph. He presented it to the Linnaean Society in 1865, publishing under the title On the Movements and Habits of Climbing Plants. In the text, Darwin linked plant movement to his evolutionary theory: plants were sensitive to their environments and used this sensitivity to guide their growth in order to survive and reproduce more successfully: Plants become climbers, in order, it may be presumed, to reach the light, and to expose a large surface of leaves to its action and to that of the free air. This is effected by climbers with wonderfully little expenditure of organized matter, in comparison with trees, which have to support a load of heavy branches by a massive trunk. Hence, no doubt, it arises that there are in all quarters of the world so many climbing plants belonging to so many different orders. สล็อตเว็บตรง
