Definition of Centrosome - Centrosomeis a more or less spherical mass of dense cytoplasm situated close to the nucleus and contains a pair of cylindrical bodies which are concerned with spindle formation during cell division. In 1888 Boveri first discovered these organelles
Robert Brown in 1831 first discovered a double membrane covered protoplasmic body that contains hereditary information. A cell usually contains a single nucleus (uninucleate, monokaryote).
Definition – Cilia and flagella are hair like micro tubular organelles projecting from the cell surface into the extra cellular medium and are concerned with cell motility.
Cytoskeletal structures are fibrous or fine tubular structures that consists of supportive structure of cell. The term cytoskeletal is coined by Koltzoff in 1928.
Ribosomes are small ,granular, non- membranous structure which is mafe up of RNA and protein and concerned with protein synthesis. In 1943 presence of ribosomes are first observed by Claude and later in 1955 Palade described a detailed description of it by define the name.
Plastids are semi-autonomous cell organelles which are surrounded by double membrane envelope, take part in storage and synthesis of organic compounds which occurred in some plant and protistans.Plastidome consists of all the whole plastids complex of cell.
The term mitochondria can be broken into mito and chondrion. The term “mito “ means fibril and” chondrion “means granule. Definition of mitochondria - The rod like filamentous, spherical or oval, double membrane bound cytoplasmic organelles of eukaryotic cells ,which are
Endoplasmic reticulum-It is discovered by Porter et al and Thompson in 1945. The name was given by Porter in 1953.It is a system of membrane lines channels found in all eukaryotic cells except mature erythrocytes.
Definition of cell wall- The thick and rigid , nonliving covering present just outside the plasma membrane of plant cells is called cell wall. It is discovered by Robert Hooke in 1665 while observing cell in the section of cork.
Definition - Cell membrane is the thin, elastic and semipermeable living membrane that surrounds the protoplasm of a cell is called cell membrane o plasma membrane or plasma lemma.
Definition of eukaryotic cell- It is a type of cell which contains well defined nucleus, membrane bound organelles. Examples of eukaryotic cell- Eukaryotic cells are present in all higher plants and animals.
Cell envelope is generally made up of three things in case of prokaryotic cells. These three things are- 1. Glycocalyx-It is located as an external covering around the cell membrane of some animal cell which is made up of glycoproteins -type of mucopolysacharides
Definition of ribosome- Ribosome is the organelles which is associated with protein synthesis. It is made up of two subunits. The larger one is spherical in shape and the smaller one is oval in shape. Ribosomes are attached with the endoplasmic reticulum and formed rough
Scientist Dougherty first classified the cells in 1957. Cells are classified on the basis of structural organisation of their nucleus into two main types that are prokaryotic cells and eukaryotic cell. The term “pro” means premitive and “karyoplasms” means nucleus.

The divisibility rule of 10 states that If the last digit of a number is 0 then the given number is divisible by 10. For eg: Check whether 5400 is divisible by 10 or not? Solution: As the last digit of the number is 0 hence, 5400 is divisible by 10
This rule states that a number is divisible by 9 if the sum of its digits of the number is divisible by 9 For eg: Check whether 729 is divisible by 9 or not? Sum of the digits = 7 + 2 + 9 = 18 Now 18 is divisible by 9 hence, 729 is also divisible by 9 Here are few examples
The most common method to check whether a number is divisible by 8 is to divide and see if the quotient is a whole number or not? If the quotient is a whole number then the given number is divisible by 8. But there is an easier way to check by using the divisibility rule.
This rule states that if the difference between twice the digit at units place and the number formed from the remaining digits of the given number is divisible by 7 then the whole number is divisible by 7.
