Seed Dispersal in Plants

Seed dispersal is an essential mechanism through which spermatophytes or seed-bearing plants disperse their seeds via dispersal agents like wind, water, fruit explosion and animals. Seeds disperse into new sites where they grow or germinate under favourable conditions. Seeds first grow into seedlings and later into well-developed plants and trees, thereby providing food, shelter and …

Difference Between Anabolism and Catabolism

The difference between anabolism and catabolism is mainly characterized due to the difference in the types of substrates participating, types of products forming and the type of metabolic phase. Small monomers function as the substrate molecules in anabolism, whereas large and complex polymers serve as the substrate molecules in catabolism. Anabolic pathways typically form complex …

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 …

Lipid Aggregates

Lipid aggregates exist in varying forms starting from monolayer to structures like lamellar, tubular, cubic etc. The different structures or aggregates of lipids are known as phases. Largely, lipids are hydrophobic or water-insoluble. Lipids assemble into microscopic aggregates in the aqueous environment because of their amphipathic nature. They possess both hydrophilic (a polar head) and …

Tropic Movements in Plants

Tropic movements in plants are the types of paratonic or induced movements. Paratonic movements include both tropic and nastic movements. In this module, we will only discuss the tropic movements in plants. Various external stimuli or environmental factors like light, gravity, water, temperature, and other factors influence tropic movement. The phenomenon of tropic movements in …

Pedigree Analysis Chart

A pedigree analysis chart provides an important tool to study the inheritance of genes. It also gives precise information about the family members through diagrammatic representation. Sometimes, it is also known as the “family or genealogic tree“. A pedigree chart uses internationally accepted symbols, lines, numbers and letters To illustrate different individuals, their interrelationship, the …

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 …

Fed-Batch Culture

Fed-batch culture is a modified batch culture method or an intermediate of batch and continuous fermentation techniques. Like batch culture, products of the fed-batch culture are harvested in batches, i.e. after the batch time. However, the substrate is added periodically throughout the cultivation, like the continuous fermentation method. Although, the amount of substrate required to …

Mode of Nutrition in Algae

The mode of nutrition in algae is primarily of three types, namely photoautotrophic, heterotrophic and mixotrophic. Algae show some properties similar to plants due to the presence of chloroplasts and eukaryotic cellular construction. Also, they share some features similar to animals in having flagella and centriole. Algae represent a group of highly diversified organisms that …
