Difference between the cell wall and the cell membrane is primarily due to the differences in three factors like composition, function and permeability. Composition: The composition of cell wall mainly comprises of proteins and carbohydrates, whereas a cell or plasma membrane comprises of lipids, proteins and some amount of carbohydrate. Function: The functional role of …
Difference between unicellular and multicellular organisms is primarily due to the difference in cell composition, cell function and cell arrangement. Cell composition: The unicellular and multicellular organisms incorporate a single cell and multiple cells, respectively. Cell’s function: Unicellular organisms mediate all their cellular activities by a single cell itself, while multicellular organisms perform specific cell …

Penicillium is a genus consisting of a group of fungi having around 354 accepted species. It also refers as “Doctor Fungi” as few members of the genus (Penicillium) can produce antibiotic to inhibit the growth of certain bacteria. Penicillium species are ubiquitous, where many produce potential mycotoxins, few produce medically useful antibiotics, and some are …
Difference between water-soluble and fat-soluble vitamins is primarily due to the difference in the process of absorption and excretion rates inside a body. Absorption: Water-soluble vitamins are readily absorbed in the small intestine, while fat-soluble vitamins are first absorbed in the lymph, later stored inside a liver and fatty tissues. Excretion: Water-soluble vitamins swiftly excrete …

Neurotransmitters also refer as “Chemical messengers” that is composed of molecules like amino acids, amines, purines and neuropeptides. Its activity can inhibit or excite the production of a nerve impulse. Its synthesis occurs endogenously by the presynaptic-neuron and releases out on membrane stimulation. Neurotransmitter ensures neurotransmission by transmitting an action potential beyond the chemical synapse. …
Synapse is a term that was first coined by Charles S. Sherrington in the year 1897 and derived from the Greek word “Synapsis” which means to conjugate or clasp. The communication between the neurons is through synapses only that helps in the transmission of a nerve signal from one to the next cell. A scientist …
Nerve impulse can define as the generation of action membrane potential beyond the cell membrane in response to the stimulus. The propagation of nerve impulse, as a result of a change in membrane potential beyond the cell membrane commonly, refers to as “Nerve impulse conduction”. When a nerve impulse or action potential reaches the axon …
Neurons are the fundamental components of the nervous system that perform a specific task by receiving, conducting, and transmitting the signal or action potential to the other parts of the body. An electrical signal produced by the neurons refers as Nerve impulse that propagates via continuous and saltatory conduction. A term neuron is sometimes interchangeable …
Sclerenchyma tissue can define as one of the types of ground or simple permanent tissue that constitutes both primary and stiff secondary wall. These are generally rigid woody cells with a compact arrangement. Sclerenchyma has a characteristic feature, where it functions to promote cell strength and conduction instead of being a dead cell. On secondary …
Motility test can consider as the biochemical or microscopic examination of an organism to check the existence of cellular-motility. By performing this test, one can differentiate between the two major groups of bacteria, namely motile and non-motile, based on their cellular movement. Few organisms are motile, whereas few are non-motile, but all the living organisms …
