Lysosomes Definition Definition: Lysosomes are single-membrane vesicles, having an intermediate size between microsomes and mitochondria. These are surrounded by a lipoprotein membrane. Lysosomes contain hydrolytic enzymes like phosphatase and ribonuclease. Due to this, they are named as lysosomes (Lyso means lytic action). Lysosomes Functions are Described below: Lysosomes Location: Lysosomes are abundantly found in Eukaryotic Animal cells. They are present… Read More »

Protein Definition: Proteins are basically biomolecules that high molecular weight polymers, polymers unruffled of α Amino acids.  α-Amino acids are joined to one another by Peptide linkage.  Peptide Linkage is represented as (-CO-NH-). Proteins are the most important elements of all living organisms. Proteins comprised of Carbon (C), Hydrogen (H), Nitrogen (N), Oxygen (O) and Sulphur (S). Proteins… Read More »

Smooth Muscle Smooth Muscles Definition: Smooth muscle is defined as a form of muscle tissue that is used by various systems in order to apply pressure to vessels and the organs. The smooth muscles are made up of sheets or strands of smooth muscle cells. These cells contain fibers of actin and myosin that run though cells and… Read More »

Synapse Synapse Definition What is a Synapse: It is a small gap at the end of neurons in the central nervous system. The synapse permits a signal to pass from one neuron to the next neuron. The synapse is a region where two nerve cells connect with each other and exchange their signals. They are the complex organization… Read More »

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 »
