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 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 …
SOS repair is one of the DNA repair mechanisms, which commonly refers to as “bypass” or “Emergency” repair. This system was first introduced in the year 1975, by a scientist named Miroslav Radman. It is a regulatory system which comprises of many complex inducer proteins that helps to repair the damaged DNA, caused due to …
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 …
The difference between chlorophyll and chloroplast is due to the following factors: Existence Chlorophyll exists as a primary photosynthetic pigment inside the chloroplast. Chloroplast exists as photosynthetic cell organelles in a plant cell and appears as a membranous structure that resembles mitochondria. Involvement in photosynthesis Chlorophyll mainly absorbs blue and red light energy from the …
