In fact, several researchers have reported that plants exposed to salinity or water stress show alterations in certain metabolites, such as primary metabolites (osmolytes, osmoprotectants) and secondary metabolites (defense metabolites). However, not all plant species synthesize all kinds of metabolites;...
Lack of water creates a survival problem for all living organisms like plants and animals. Animals are more susceptible to extremes in temperature than plants, which makes living in a desert habitat more challenging. Desert animals–like reptiles, certain birds and mammals–have evolved behavioral an...
Flooding frequencies and intensities determine both species composition and the behaviour of individual plants along many rivers in the world. In this context, this paper describes the vegetation zonation associated with the fluctuating water levels of the river Rhine in the eastern part of The Netherl...
Plants that grow in water have special adaptations. Lilies are often seen in ponds. Do lilies grow in water? A. Yes B. No C. Maybe 相关知识点: 试题来源: 解析 A。解析:文中提到生长在水中的植物有特殊的适应性,百合花经常在池塘中看到,说明百合花生长在水中。
Plants live in environments where they are constantly, and often simultaneously, exposed to different types of biotic and abiotic stress, such as insect herbivory and water availability. How plants are adapted to abiotic conditions may determine how a surplus or shortage of water affects plant resist...
Some partially-submerged aquatic plants, such as the water lily, have large and flat leaves grow above the surface of water, allowing it to obtain sunlight for photosynthesis. The stomata of such leaves may be found mostly on the upper side of the leaves to facilitate gaseous exchange with th...
THE leaves of plants which are found growing in dry situations often show certain structural characteristics in common鈥攖hick-walled tissues, thick cuticles, stomata sunken below the surface, etc. These structural features seemed likely to cut down the loss of water from the leaf, and therefore...
Plants with bare stems have a higher probability of dying than control plants during the... AP Smith - 《Biotropica》 被引量: 87发表: 1979年 INFLUENCE OF INSULATING DEAD LEAVES AND LOW-TEMPERATURES ON WATER-BALANCE IN AN ANDEAN GIANT ROSETTE PLANT Espeletia schultzii (Compositae) Wedd., a ...
