The onion peel cell experiment is very popular for observing a plant cell structure. Onion is a eukaryotic plant that contains multicellular cells. We know that the cell is a structural and functional unit of life that builds up living structures. The bulb of onion is formed from modified leaves. Like plant cells, onions cells …
Water is a solvent that dissolves a variety of substances. It is considered the universal solvent because it can dissolve compounds (like polar molecules and ions) than the available solvents. Its physical and chemical attributes make it an excellent solvent. The chemical formula of water is H2O, i.e. it contains two H-atoms and one O-atom. …
The difference between polyp and medusa relies upon motility and shape. Members of the phylum Cnidaria have two different forms of individuals or zooids (polyp and medusa). Polyps are the sessile or fixed individuals, while medusae are motile or free-swimming zooids. Polyps appear more or less cylindrical, whereas medusae appear umbrella-shaped. Cnidarians can exist as …
Binary fission is an asexual method of cell reproduction. The word asexual implies a reproduction that does not involve sex cells or gametes. Instead, the somatic cells take part in the asexual process that forms a clone of the parent. Fission is a process in which an organism divides into two or more fragments. Further, …
An acid-base titration is one of the titration methods. First and foremost, we should know what titration is and what it requires to conclude the results. A titration is a quantitative chemical analysis that helps in determining an unknown concentration of a solution by the known concentration of a solution. It must be clear that …
Abiotic factors are the ones with the non-living origin but have a major influence on the living organisms associated with the ecosystem. These include physical components like air, water, light, soil, temperature etc. We can define the term abiotic by breaking it into ‘A‘ (means without) and ‘Biotic‘ (means life). Abiotic factors can be physical …
Sepals and petals differ more or less based on their colour, shape and size. Petals are fluorescently coloured with a symmetrical or asymmetrical shape, and their size varies from plant to plant. In contrast, a sepal in most flowers appears green in colour with varying shapes and sizes. A flower is dichlamydeous when a perianth …
Hydroponic systems cultivate plants in nutrient-rich water with or without using non-soil growing media around the root system. It includes deep water culture, wick system, Ebb and flow, nutrient film technique, drip system and aeroponics. For the commercial production of plants through hydroponics, a greenhouse is recommended best to cultivate plants like tomatoes, peppers, lettuces, …
Colony morphology of bacteria refers to the macroscopic features or cultural characteristics of bacterial masses grown on the nutrient culture media. Bacteria are diverse, and every species have unique culture and growth characteristics. We can distinguish the colony morphology by looking at the bacterial mass on or in the nutrient base. In microbiology, a colony …
Endosmosis is the diffusion of water from the cell exterior to the cell interior or cytoplasm. The study of endosmosis is possible if you keep a cell in the hypotonic solution. In endosmosis, the solute and solvent concentration inside and outside the cell are as follows: High solvent and low solute concentration in the cell …
