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 …
Mitotic division shows a pattern of cell division, where a single cell multiplies into two similar daughter cells by the segregation of newly replicated chromosomes in the nucleus. It is the intermediate phase of the cell division that activates after the G-2 interphase and ends with the stage of cytokinesis. Mitosis is a part of …
The difference between RBC and WBC is mainly due to the following properties like: Colour: As the name, red blood cell and white blood cell itself clears the colour difference, but the reason behind the red colour of RBC is due to the iron atom present in the haemoglobin pigment. The white blood cells are …
Shoot system of the plant is an outgrowth originates from the plumule of the seed’s embryo, above the ground. A term shoot is generally interchangeable with the stem, as it constitutes the major part of the shoot system. The morphology and physiology of the shoot system are more complex than the root system of the …
Parenchyma in plants are the types of simple permanent tissue which has some of the ideal properties that distinguish it from the other cells: Cell division: Parenchyma tissue has not the ability to undergo cell division. Vacuole: These comprises a large vacuole. Nature: Structurally and physically, parenchyma is a kind of unspecialized tissue. Modification: Parenchyma …
Difference Between light reaction and dark reaction are mainly due to the following properties: The demand for light: A light reaction demands the source of light energy for the breakdown of water into oxygen, while dark reaction does not need a light source. Site of occurrence: A light reaction resides within the thylakoid membrane, whereas …

Chlorophyll in plants is a pigment molecule that imparts green colour to the leaf and stems by absorbing a red and blue spectrum of light. The term chlorophyll has originated from the Greek terms “Khloros” which means green and “Phyllon” which means leaf. It plays a fundamental role in the process of photosynthesis by allowing …
The difference between root and stem is due to the following properties like: Origination: Roots originate from the radicle by the germination of seed whereas shoots originate from the plumule of developing the embryo. Arrangement of vascular bundles: In roots, the vascular bundles are arranged in the central core while in shoots, arranged in a …
Chloroplast in a plant cell is a membrane-bound cell organelle, contain chlorophyll pigments that are absent in the animal cell. The study of chloroplast was first carried by a scientist named Hugo Von Mohl in the year 1837. After his study, it was found that the chloroplasts were the type of plastids and hence it …
