Ex-Situ Biodiversity Conservation

Ex-situ biodiversity conservation refers to one of the approaches of conserving biodiversity that ensure the survival and sustainability of endangered plants and animal species outside their native habitat. It provides an artificial environment for diverse plants and animals similar to their actual growth conditions. It is also termed as “Off-site conservation”. Human activities and some …

Difference Between Osmotic Pressure and Osmotic Potential

The difference between osmotic pressure and osmotic potential is characterized by the properties like a chemical equation, effect of solute particles and types of system where it develops. The chemical equation for the osmotic pressure is equal to the product of molar concentration, gas constant and temperature. In contrast, the chemical equation for the osmotic …

Difference Between Plasmolysis and Deplasmolysis

The difference between plasmolysis and deplasmolysis is mainly due to factors like: Water movement: In plasmolysis, the movement of water is from the cell protoplast to the surrounding and deplasmolysis cause movement of water into the cell protoplast. Water potential: Plasmolysis occurs due to the low water potential of the surrounding than the cell cytoplasm, …

Ozone Formation

Ozone formation takes place differently in the stratosphere region and the troposphere region of the earth’s atmosphere. The heat or sunlight causes chemical changes or dissociates molecules of oxygen into individual atoms, which can further react with the atmospheric oxygen to form stratospheric ozone. In contrast, the heat or sunlight causes chemical reactions in the …

Floral Formula

A floral formula is one of the ways to summarise all the flower characteristics, which makes the use of discrete letters, numbers and symbols. The letters used in the floral formula indicate the members of the perianth and other floral parts. Specific signs or symbols are also used to denote the properties like parentheses, aestivation, …

Solenoid Model

The solenoid model illustrates the packaging or folding of DNA within the eukaryotic cell nucleus. It was first introduced by the scientist’s John Finch and Aaron Klug in the year 1976. In eukaryotes, the DNA is organized compactly due to the association of bead-like histone octamer and linker histones. Oppositely, the DNA content in prokaryotes …

Plant Cell Nucleus

A plant cell nucleus is a specialized structure, which stores genetic information and monitors cellular activities. Plants are monokaryotic cells, which possess an individual nucleus. A well-developed nucleus is only found in the advanced or multicellular organisms, those having division of labour. Nucleus presence is a prominent feature in plant cells, as it plays a …
