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 …
The difference between mules and horses relies upon their parents and fertility. Horse and Mule belong to the same family, ‘Equidae’ and more or less they look very similar. But, both the creatures have different physical and genetic traits that we will discuss in this post. A mule is an animal created by breeding donkeys …
A study of osmosis can be done using a potato osmometer. Osmosis is a phenomenon in which water moves from high solvent to low solvent concentration. The movement of water occurs between two compartments, separated by a semipermeable membrane. The cell membrane of living organisms behaves as a semipermeable or selective membrane. The permeability of …
Digestive glands in the human body play an important role in food digestion. These are associated with the alimentary canal to aid the process of digestion. The salivary gland, liver and pancreas are the accessory digestive glands. Gastric and intestinal glands are the digestive glands present in the lining of the stomach and small intestine. …
The structure of paramecium seems slipper-like. Paramecium comprises organelles common to eukaryotes. They contain specialized membrane-bound organelles and a well-defined nucleus. Besides that, they are unique in having contractile vacuoles, mouth pore and anal pore. Paramecium contains organelles necessary to sustain life, including growth, metabolism and reproduction. For the movement, they have small hair-like outgrowths …
The difference between amoeba and paramecium relies on locomotion. Amoeba moves and feeds with pseudopods or temporary extensions. Activation of microfilament polymerization propels the cell membrane, ensuing pseudopodia formation. Paramecium moves through short hair-like cilia. Many tiny hair-like cilia are present throughout the pellicle. Its number varies from species to species. Oral cilia surround the …
