In plants, their accumulation can increase survival during stresses such as drought. In extreme cases, such as in bdelloid rotifers , tardigrades , brine shrimp , and nematodes , these molecules can allow cells to survive being completely dried out and let them enter a state of suspended animation called cryptobiosis .
Ecological empathy, or eco-empathy, is empathy directed towards the natural world. It encompasses empathy directed towards animals, [1] plants, ecosystems, and the earth as a whole. [2] Kim-Pong Tam developed a method of measuring individuals' dispositional empathy with nature (DEN), and has demonstrated its robust connection to conservation ...
One way that plants alter their morphology is by reducing the area of their leaves. Though large and flat leaves are favorable for photosynthesis because there is a larger surface area for the leaf to absorb sunlight, bigger leaves are more vulnerable to environmental stresses.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
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 ...
This allows the mollusks to survive solely by photosynthesis for several months at a time. [66] [67] Some of the genes from the plant cell nucleus have even been transferred to the slugs, so that the chloroplasts can be supplied with proteins they need to survive. [68] An even closer form of symbiosis may explain the origin of chloroplasts.
A plant produced in this way is called an apomict. apomorphy In cladistics, a "different form" from the form of an ancestor (i.e., an innovation) of use in determining membership in a clade. apopetalous Having separate petal s, not fused (sympetalous). apophyllous Perianth or other segments free, not united.
Plant ecophysiology is concerned largely with two topics: mechanisms (how plants sense and respond to environmental change) and scaling or integration (how the responses to highly variable conditions—for example, gradients from full sunlight to 95% shade within tree canopies—are coordinated with one another), and how their collective effect on plant growth and gas exchange can be ...
