Asexual vs Sexual Reproduction- Definition, 16 Differences, Examples

Differences Between Asexual and Sexual Reproduction

Asexual Reproduction Definition Asexual reproduction is a mode of reproduction that occurs without the fusion of gametes and doesn’t involve the exchange of genetic information, resulting in offsprings identical to their parents. Asexual reproduction in living beings is characterized by the absence of male and female gametes and the lack of change in the number of chromosomes in the offspring. As no specific gametes are formed during asexual reproduction, the somatic cells act as gametes. The body of the organism … Read more

Definition Organisms made up of cell(s) that lack a cell nucleus or any membrane-encased organelles. Organisms made up of cells that possess a membrane-bound nucleus as well as membrane-bound organelles. 3. Major groups Bacteria, Archae, and Bluegreen algae Algae, fungi, protozoa, plants, animals 4. Origin Around 3.5 billion years ago. Around 2 billion years … Read more

Habitat vs Niche- Definition, 14 Major Differences, Examples

Differences between Habitat and Niche (Habitat vs Niche)

Habitat Definition A habitat is a natural environment where a particular organism lives and utilizes the resources of that place for its survival, food, shelter, protection, and mating. The term habitat has been derived from the Latin word, ‘habitāre’ which means ‘to inhabit’. The habitat of an organism is characterized by its physical and biological characteristics. The physical factors include the nature of the soil, availability of land, sunlight, temperature, and climatic conditions. The biological factors include the availability of … Read more

Flora vs Fauna- Definition, 12 Major Differences, Examples

Differences between Flora and Fauna (Flora vs Fauna)

Flora Definition The term ‘flora’ is defined as all the naturally occurring native plants of a particular region. Flora indicates all forms of plant life, more generally used to represent the plant life of a particular place. Sometimes, the term ‘microflora’ or ‘gut flora’ is used to represent the naturally occurring microorganisms, mainly, bacteria and fungi, in various organisms. The word, ‘flora’ is taken from the Latin name of the Goddess of plants in the Roman mythology who was named … Read more

Epithelial vs Connective tissue- Definition, 15 Differences, Examples

Differences between epithelial tissue and connective tissue

Epithelial Tissue Definition Epithelial tissue is a type of animal tissue, consisting of closely aggregated polyhedral cells connected firmly to one another in the form of cellular sheets that line the interior of hollow organs and cover the body surface. Cells in epithelial tissue or epithelium (epithelia; plural) are arranged in continuous sheets, in either single or multiple layers. The shapes and sizes of cells in the epithelium tissue range from tall columnar to cuboidal to low squamous, and often … Read more

Diploid vs Haploid- Definition, 12 Major Differences, Examples

Differences between Diploid and Haploid (Diploid vs Haploid)

Image Source: BioNinja. Diploid Definition Diploid is a cell or organism that has paired chromosomes, one from each parent. In most organisms, the somatic cells are diploid, whereas the sex cells tend to be haploid. The diploid cells have two homologous copies of the two chromosomes obtained from two parents. Almost all mammals are considered diploid organisms except for some rats. However, studies discarding the existence of polyploidy in mammals have been done. Polyploidy is the condition where a cell … Read more

Arteries vs Veins- Definition and 27 Major Differences

Differences between Arteries and Veins

Differences between Arteries and Veins Arteries and veins are two of the body’s main type of blood vessels through which blood flow in the body. The arteries carry oxygenated blood away from the heart while the veins carry deoxygenated blood from the tissue capillaries back towards the heart. Image Source: West Florida Vein Center and Wapcaplet, Yaddah. Here are some of the differences: S.N. Character Arteries Veins 1.       Definition Blood vessels that transport blood away from the heart. Blood vessels that transport … Read more

Exotoxins vs Endotoxins- Definition and 29 Major Difference

Differences between Exotoxins and Endotoxins

Differences between Exotoxins and Endotoxins Toxins are small molecules, peptides, or proteins produced by living cells that are capable of causing diseases or structural damage when they come in contact or are absorbed by tissues. Toxins and enzymes play an important role in the pathogenicity of pathogenic bacteria. Toxins may aid in invasiveness, damage cells, inhibit cellular processes, or trigger immune response and damage. Toxins are of two types: Exotoxins and Endotoxins. S.N. Character Exotoxins Endotoxins 1.       Definition Proteins produced … Read more

Chromosome vs Chromatid- Definition, 11 Differences, Examples

Differences between Chromosome and Chromatid (Chromosome vs Chromatid)

Chromosome Definition A chromosome is a thread-like structure present in the nucleus or nuclear region of the cytoplasm that is made up of a single molecule of DNA (Deoxyribonucleic acid) and proteins, carrying some or all genetic materials of an organism. These chromosomes are only visible under the light microscope during the metaphase of the cell cycle where the chromosomes line up in the center of the cell. Prokaryotes have a single circular chromosome that is organized in the nucleoid … Read more
