Difference between active transport and passive transport

Difference between active transport and passive transport

Difference between active transport and passive transport Active and passive transport are the two main biological process which plays an important role in supplying nutrients, water, oxygen, and other essential molecules to cells and also by removing waste products. Both active and passive transport works for the same cause, but with different movement. Active transport … Read moreDifference between active transport and passive transport

Haeckel’s Three kingdom System of Classification

Haeckel’s Three kingdom System of Classification

Haeckel’s Three kingdom System of Classification Classification is the arrangement of organisms into taxonomic groups known as taxa on the basis of similarities or relationships. Closely related organisms (i.e., organisms having similar characteristics) are placed into the same taxon. Organisms are categorized into larger groups based on their similarities and differences. The classification of living … Read moreHaeckel’s Three kingdom System of Classification

Five Kingdom System of Classification- Features and Limitations

Five Kingdom System of Classification

Five Kingdom System of Classification- Features and Limitations Taxonomy refers to the science of classification of living organisms. According to Bergey’s Manual of Systematic Bacteriology, taxonomy consists of three separate but interrelated areas: classification, nomenclature, and identification. Classification is the arrangement of organisms into taxonomic groups known as taxa on the basis of similarities or … Read moreFive Kingdom System of Classification- Features and Limitations

Oxygen Release in Photosynthesis Protocol

Oxygen Release in Photosynthesis Protocol

Oxygen Release in Photosynthesis Protocol Photosynthesis is the biological process that converts sunlight into chemical energy. It is employed by plants, algae and certain bacteria. It provides the basis for life on Earth and is the ultimate source of all fossil fuels and of the oxygen we breathe. There are a few key methods to … Read moreOxygen Release in Photosynthesis Protocol

Isolation of Mitochondria from Plants, Yeast Cells, Mice, Cell Culture

Isolation of Mitochondria from Cell Culture

Isolation of Mitochondria from Plants, Yeast Cells, Mice, Cell Culture Mitochondria are central organelles controlling the life and death of the cell. They participate in key metabolic reactions, synthesize most of the ATP and regulate a number of signaling cascades, including apoptosis. Investigating functional mitochondria that have been isolated from different tissues and from cultured … Read moreIsolation of Mitochondria from Plants, Yeast Cells, Mice, Cell Culture

Chromosomes- Abnormalities and Disorders

Chromosomes- Abnormalities and Disorders

Chromosomes- Abnormalities and Disorders Chromosomes refer to any of the rod-shaped or threadlike DNA-containing structures of cellular organisms that are located in the nucleus of eukaryotes, are usually ring-shaped in prokaryotes (such as bacteria), and contain all or most of the genes of the organism. Simply put, it is a strand of DNA that is … Read moreChromosomes- Abnormalities and Disorders

Mendel’s Experiment and Laws

Mendel's Experiment

Mendel’s Experiment and Laws In the 1860’s, an Austrian monk named Gregor Mendel introduced a new theory of inheritance based on his experimental work with pea plants. Mendel believed that heredity is the result of discrete units of inheritance, and every single unit (or gene) was independent in its actions in an individual’s genome. According to … Read moreMendel’s Experiment and Laws

Chromosome- Structure, Types and Functions

Chromosome- Structure, Types and Functions

Chromosome- Structure, Types and Functions In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes were first described by Strasburger (1815), and the term ‘chromosome’ was first used by … Read moreChromosome- Structure, Types and Functions

Nitrogen Cycle- Steps and Significance

Nitrogen Cycle- Steps and Significance

Nitrogen Cycle- Steps and Significance The movement of nitrogen between the atmosphere, biosphere, and geosphere in different forms is called the nitrogen cycle and is one of the major biogeochemical cycles.  It may also be considered as the movement of nitrogen through the food chain from simple inorganic compounds, mainly ammonia, to complex organic compounds. This complex cycle involves bacteria, plants and … Read moreNitrogen Cycle- Steps and Significance

Differences between Enzymes and Hormones

Differences between Enzymes and Hormones

Differences between Enzymes and Hormones Enzymes and hormones are bio-genic substances present in all living organisms whose function, formation, secretion and purpose varies in both plants and animals. An enzyme is a highly selective catalyst that greatly accelerates both the rate and specificity of metabolic reactions. A hormone, on the other hand, is a chemical released … Read moreDifferences between Enzymes and Hormones
