Transitional Epithelium Transitional Epithelium Definition: What is Transitional epithelium: It is defined as a stratified tissue composed of multiple cell layers, where cells constitute the tissue may change shape on the basis of distention on the organ. When an organ filled with fluid, the cells present on the topmost layer of the transitional epithelium may stretch and look… Read More »
Chloroplasts Definition Biology: The chloroplast is the organelle that has the ability to use light as a source of energy for sugar synthesis from water and carbon dioxide is a special feature of certain plant cells. This process termed photosynthesis is carried out by these organelles. Chloroplast Function Described Below: Chloroplast Function Chloroplast Location Depending on the plants it… Read More »
Neuron What is a Neuron? The neuron is a nerve cell that is a specialized cell in the transmitting of nerve impulses. Neurons used to send signals to the brain, muscles, and glands. There are about 100 billion neurons in the brain to send signals. The signals transfer by neurons help the different parts of the body to communicate… Read More »
What are Waxes in Biology? Waxes Lipids: Waxes Definition: Waxes are the organic compounds composed of lipophilic compounds and malleable solids. Waxes form the protective coating by the mixture of long-chain apolar lipids. In plants, wax forms a protective coat of cutin on plants, leaves, and fruits. Waxes Structure Defined Below. Where does Waxes Come from: There are two types of waxes: True waxes… Read More »
Peroxisomes Definition: Peroxisomes are otherwise known as microbodies. They are single-membrane vesicles of regarding 0.5 millimeters in diameter. They contain an enzyme, D-amino acid enzyme, salt enzyme, and alternative aerophilous enzymes. Peroxisomes contain a range of enzymes, that primarily operate along to rid of the cell of cyanogenetic substances, and especially, oxides. Peroxisomes Structure Described Below: Peroxisome Location: Peroxisome,… Read More »
Golgi Body Definition: Golgi apparatus was discovered in 1898 by an Italian biologist Camillo Golgi. Golgi apparatus is also called the Golgi complex or Golgi body. Golgi apparatus is a set of the single membrane-bound organelle. That is found in eukaryotic cells only. Eukaryotic cells are those cells which have clearly defined nuclei. Golgi Apparatus Function described Below. Golgi… Read More »
Dendrite Dendrite Definition: What is a Dentrite: The word dendrite derived from the Greek word “Dendron”, which means the ‘tree’ or the ‘branched such as e tree’. The dendrite is a short arm like protuberance from a neuron. Dendrites work as transmitters and receivers for chemical messages between the cells. Dendrites used to receives from the nerve cell… Read More »
Plant Cell Plant Cell Definition For the living organisms of Kingdom Plantae, Plant cells are the functional unit of life. Plants cells are usually Eukaryotic cells. They have specialized peripheral Nucleus and other specialized structures along with nucleus also present which are called Organelles. Inside the plant cell, each organelle performs a specialized function according to its structure. Due to… Read More »
Electron Transport Chain Electron Transport Chain Definition: Electron Transport Chain (ETC) is the moving of electrons through a series of electron transporters that undergo a redox reaction. Hydrogen ions accumulate in the form of matrix space with the help of an electron transport chain. A concentration gradient creates in which diffusion of hydrogen ions occurs by passing through… Read More »
Placenta Placenta Definition What is Placenta: It is basically a structure that is responsible for not only provide nutrients as well as protecting the site for a developing fetus during the gestation time period. It is inimitable as well as it is a momentary organ within the female body. Throughout the pregnancy, the period fetus grows, and then… Read More »
