(Science: chemistry) An atom or or electrically neutral group that has one or more unpaired electrons. 2. (Science: botany) Of leaves, clustered at the base of the stem.

What is a radical in biology Brainly?

Explanation: A radical is an atom or group of atoms that have one or more unpaired electrons.

What is radical and example?

The definition of radical is something that is at the root of something, or something that changes, addresses or affects the major essence of something. An example of radical is a basic solution to a complex problem. An example of radical is the change that allowed women to vote. adjective.

What is free radical in biology?

Listen to pronunciation. (free RA-dih-kul) A type of unstable molecule that is made during normal cell metabolism (chemical changes that take place in a cell). Free radicals can build up in cells and cause damage to other molecules, such as DNA, lipids, and proteins.

What is a radical reaction?

A radical substitution reaction is a reaction which occurs by a free radical mechanism and results in the substitution of one or more of the atoms or groups present in the substrate by different atoms or groups. The initiation step in a radical chain reaction is the step in which a free radical is first produced.

What is radicle and Plumule?

Plumule is the embryonic shoot of the plant. Radicle is the first part of the seedling. Plumule grows after the radicle. The radicle makes the root of the plant.

What is radical biology class 11?

Radicle is a small embryonic root of the plant. It is a part of the seedling, which rises first from the seed during the process of seed germination.

What is radical form?

If n is a positive integer that is greater than 1 and a is a real number then, n√a= a1n. where n is called the index, a is called the radicand, and the symbol √ is called the radical. The left side of this equation is often called the radical form and the right side is often called the exponent form.

What are radicals give two example?

The compounds containing compound radicals give out compound radicals in their aqueous solutions. Examples of compounds containing compound radicals are as follows: Sulphuric acid (H2SO4): H2SO4 has compound radical SO2−4. Nitric acid (HNO3): HNO3 has compound radical NO−3.

What does thats radical mean?

If something is considered extremist or very different from anything that has come before it, call it radical. In more everyday language, a radical is someone who has very extreme views, so you could say that their views are different from the root up.

How are radicals used in biology?

Radicals are actually found throughout biology. They play a central role in cofactor biosynthesis used to expand the repertoire of enzyme-catalyzed reactions (6) and are essential for many metabolic transformations in primary and secondary metabolism and in cell signaling.

Is oxygen a free radical?

Oxygen as a free radical Probably the most well-known free radical, oxygen is the basis for development of most free radicals in the body. Inherently, oxygen is an unstable molecule.

What is an antioxidant do?

Antioxidants are substances that may protect your cells against free radicals, which may play a role in heart disease, cancer and other diseases. Free radicals are molecules produced when your body breaks down food or when you’re exposed to tobacco smoke or radiation.

What is basic radical?

Basic radical is an ion coming from a base. It is a positively charged chemical species; thus we name it as the cation. Moreover, it is a portion of an inorganic salt. This ion forms as a result of the removal of a hydroxide ion from a base.

What is difference between radical and ion?

An ion has a non-zero electric charge. A radical has an atom with unfilled electron shells and so is very reactive, but is electrically neutral.

What is radical reaction example?

Radical reactions are very often initiated by light and are not dependent on polarity of the reaction medium. Halogenation of alkanes is a good example of free radical reaction, esp. the chlorination of methane where chloroform(trichloromethane) and tetrachloromethane are formed.
