Plant cognition. Plant cognition or plant gnosophysiology[1] is the study of the learning and memory of plants, exploring the idea it is not only animals that are capable of detecting, responding to and learning from internal and external stimuli in order to choose and make decisions that are most appropriate to ensure survival.
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]A germination rate experiment. 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 ...
A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the ...
Plant cells differentiate from undifferentiated meristematiccells (analogous to the stem cells of animals) to form the major classes of cells and tissues of roots, stems, leaves, flowers, and reproductive structures, each of which may be composed of several cell types. Parenchyma. Parenchyma cellsare living cells that have functions ranging ...
Internally, a tuber is filled with starch stored in enlarged parenchyma-like cells. The inside of a tuber has the typical cell structures of any stem, including a pith, vascular zones, and a cortex. [citation needed] The tuber is produced in one growing season and used to perennate the plant and as a means of propagation. When fall comes, the ...
Plant communication. Plants are exposed to many stress factors such as disease, temperature changes, herbivory, injury and more. [1] Therefore, in order to respond or be ready for any kind of physiological state, they need to develop some sort of system for their survival in the moment and/or for the future.
The nerve cells can be thought of as intermediary's, not so much communicating with each other but rather passing on the messages from one neighboring cell to another. Being "accessory" cells that pass on the message they require an additional space and can consume a lot of energy within an organism. [38] Ctenophore neural systems.
v. t. e. In physiology, a stimulus[ 1 ] is a change in a living thing's internal or external environment. This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. [ 2 ] Sensory receptors can receive stimuli from outside the body, as in touch receptors found in the skin or light receptors in ...
