Vernalization defines as a process of growing flowers and fruits through a phase of cold treatment. It reduces the time period of the juvenile vegetative growth phase in the plants. The active meristematic cells of the shoot apex, root apex, embryo tips etc. participate in the production of stimulus refers as “Vernalin”. The term vernalization …
Collenchyma tissue is a term given by a scientist named Schleiden in the year 1839. It is a kind of simple permanent supportive tissue that confers mechanical strength to the plant. The collenchyma cells appear as elongated cells with the non-uniform thickened cell wall. It originates by the modification of parenchyma tissue into the cells comprising …
Difference between ATP and ADP is mainly due to the given three factors like their energy state, a number of phosphate groups and the hydrolysis process. Energy state: ATP is comparatively high energy molecule than ADP. Phosphate group: There are three phosphate group in ATP, while two in ADP. Hydrolysis: As a result of hydrolysis, …
Membrane proteins are the binding proteins that mediate conduction of ions or molecules into and out of the cell membrane. It has three major kinds, namely integral, peripheral and lipid-anchored membrane proteins. The membrane protein is the principal constituent of the cell membrane that contributes to the structure of the plasma membrane. The attachment of …
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 …
