OUR BUILDING BLOCK CELL

You all are familiar with the wall of your home the bricks are used to build the wall or we can say that that the bricks are the smallest unit of the wall. Now when we talk about our living thing all living thing is made up of smallest unit called cell The combination of bricks change into wall and combination of cell change into body there are many latest research and experiment takes places daily in the scientific libratory stem cell is an example of it. Stem cell is found in human body which helps in synthesize the organ of the body. It is the great discovery in medical science with the help of stem cell we recover many disease we will learn about stem cell in detail

Now at first we will discuss on feature is cell what are the organ involve in cell and what is the function of all in parts.

The smallest unit of living thing is cell the combination of cell is called tissue combination of tissue is called organ combination of organ formed organ system and combination of organ system forms a complete body.

The cell has very small in size so it can't be see by eye directly. At first cell was discovered by Robert hook that see the cell by microscope. Microscope is a device which used to magnify or enlarge the image of object which is examined under the microscope.

Now further experiment takes place after that various organelles in the cell had discover now one by one I give you the brief introduction of all the organelles of the cell

Plasma membrane/cell membrane – it is the outer covering of the human cell are called the boundary of the cell it encloses the liquid called protoplasm the cell membrane regulate the flow of substance through it. Provide the shape to cell

Cell wall – it is the outermost covering the plant cell it cover the plasma membrane it also give support to plant and give shape to plant cell .

Protoplasm – it is a liquid enclosed by plasma membrane which contains carbohydrates, portion, fates, nucleic acid and mineral acid.

Nucleus- it is situated in the center of the cell it contain fibers like structure called chromosomes. Which help in transfer of character to one generation to other generation. It also controls the activity of the cell.

Nuclear membrane- the protoplasm and necleoplasm is bounded by a membrane is called nuclear membrane

Plastids- it is found in plant cell which contain color pigment

Chloroplast- the green color pigment in the cell is called chloroplast

Mitochondria- it is rod shaped spherical organ which is also main parts of the cell which is used in to synthesis of food due to this the mitochondria is called kitchen of the cell.

Vacuole- it is found in the both plant and animal cell the main function of the vacuole is to store the food the vacuole of plant is larger than the vacuole of animal.

Endoplasmic raticulm- it can call the brain of the cell the main function is to manufacturing and packaging of food in the cell.

Golgi apparatus- it is found in cell the main function is to synthesis of protein and lipid  

lysosomes- it contains the digestive enzyme it help in digestion of food inside the cell  is is also called suicidal bag  

Above I give the brief introduction of the organelles of the cell now we also know about the cell. There is various type of the cell some have spherical, round, cubed and so on. 

red blood cell found in blood of animal 

Some of the animals are single celled like amoeba; paramecium and many are multi cellular like all of us. It is the brief profile of the cell in further coming article we cover study about the tissue and the organ system . the bigest cell which can be see by unnaied eye is egg of ostrich
