Mendelian inheritance is an approach that explains the traits are the characters inherit from one generation to another by the discrete units, which later termed as genes. It also refers as “Mendelism” which was introduced by the botanist or an Austrian monk, Gregor Johann Mendel. Sir Mendel was honoured as “Father of Genetics” for his …
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 term 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 …
SOS repair or “bypass” or “Emergency” repair is one of the DNA repair mechanisms, introduced in the year 1975, by a scientist named Miroslav Radman. It serves as a regulatory system, which comprises of many complex inducer proteins that repair the damaged DNA. SOS repair primarily recover the DNA damage caused due to the environmental stresses. …
Parenchyma in plants are the types of simple permanent tissue which possesses some of the ideal properties that discriminates it from the other cells. Cell division: Parenchyma tissues lack the ability to undergo cell division. Vacuole: They comprises a large vacuole. Nature: Structurally and physically, parenchyma is a kind of unspecialized tissue. Modification: Parenchyma modifies …
The difference between light reaction and the dark reaction is mainly due to the following properties: The demand for light: A light reaction demands a source of light energy for breaking down water into oxygen, while dark reaction does not need a light source. Site of occurrence: A light reaction occurs within the thylakoid membrane, …

Chlorophyll in plants refers to a pigment molecule that imparts a green colour to the leaves and stems by absorbing a red and blue spectrum of light. The term chlorophyll has originated from the Greek terms “Khloros” (green) and “Phyllon” (leaf). It plays a fundamental role in the process of photosynthesis by allowing plants to …
The difference between root and stem is due to the following properties like: Origination: Roots originate from the radicle through the germination of seed, whereas shoots originate from the plumule of the developing embryo. Arrangement of vascular bundles: In roots, the vascular bundles reside within the central core, while shoots have dispersed vascular bundles. Presence …
Chloroplast in a plant cell exists as a membrane-bound cell organelle, and contain chlorophyll pigments that are absent in the animal cells. 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 …
The difference between chlorophyll and chloroplast is due to the following factors like location and involvement in photosynthesis. Existence: Chlorophylls exist as the primary photosynthetic pigments inside the chloroplast. Conversely, chloroplasts exist as the photosynthetic cell organelles in a plant cell and possess a membranous structure that resembles mitochondria. Involvement in photosynthesis: Chlorophyll mainly absorbs …
