The key difference between open circulatory system and closed circulatory system is that in open circulatory system, blood and interstitial fluid mix with each other while in closed circulatory system, blood and other fluids never mix with each other. Open circulatory system and closed circulatory system are two ways in which the circulatory system is […]
Difference Between Gene and Allele
The key difference between gene and allele is that the gene is a specific nucleotide sequence that encodes for a specific protein while the allele is a variant of a gene either the dominant or the recessive variant. A gene is the basic unit of heredity. Specifically, it has a precise nucleotide sequence that encodes […]
Difference Between Cell Wall and Cell Membrane
The key difference between cell wall and cell membrane is that the cell wall is a fully permeable cell layer present in bacteria, plants, fungi and algae while the cell membrane is a selectively permeable membrane present in all cell types including the animal cells. Cell membrane (plasma membrane) and cell wall are the outermost […]
Difference Between Living Things and Non-living Things
The key difference between living things and non-living things is that the living things are organisms that are alive and composed of cells and tissues while non-living things are objects or items that do not exhibit any sign of life. Everything around us in our environment consists mainly of two main types such as living […]
Difference Between Molds and Yeasts
The key difference between molds and yeasts is that the molds are multicellular filamentous fungi whereas the yeasts are unicellular round or oval fungi. Kingdom fungi are one of the five kingdoms that include eukaryotic microorganisms such as yeasts, molds rusts, smuts, mildews and mushrooms. They are very vital and useful decomposers in the environment […]
Difference Between Plant and Animal Cells
The key difference between plant and animal cells is that the plant cells have a cell wall composed of cellulose at the outside to the cell membrane while the animal cells lack a cell wall outer to the cell membrane. A cell is the fundamental unit of the living organisms. Some organisms are unicellular while […]
Difference Between Mold and Mildew
The key difference between mold and mildew is that the mold has a fuzzy appearance and often appears as black, green, red patches that penetrate beneath the surface while the mildew has a powdery appearance and often appears as grey or white patches that grow only on the surface. Mold and Mildew are two very […]
Difference Between Annual and Perennial Plants
The key difference between annual and perennial plants is that annual plants complete their life cycle in one season, especially during one year, while perennial plants grow and spread for more than two years, showing a longer life cycle. Any proud homeowner would like to have both annuals and perennials in his or her garden. […]
Difference Between T Lymphocytes and B Lymphocytes
The key difference between T lymphocytes and B lymphocytes is that the T lymphocytes originate in bone marrows and mature in the thymus while B lymphocytes originate and mature in bone marrows. The main two types of cells in blood are red blood cells (RBC) and white blood cells (WBC). RBC carries and transports oxygen […]
Difference Between DNA and RNA
The key difference between DNA and RNA is that DNA is a type of nucleic acid consisting of deoxyribonucleotides while the RNA is the second type of nucleic acid consisting of ribonucleotides. There are two main types of nucleic acids in a cell such as DNA and RNA. DNA stands for deoxyribonucleic acid while RNA […]
