Answer:-

What is a cell?

• Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.

• All living organisms on Earth are divided into cells. The main concept of cell theory is that cells are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive and successful. Living things may be single-celled or they may be very complex such as a human being.

And why cell is necessary to live?

What are WBCs and RBCs?

• White blood cells (WBCs), or leukocytes, are a part of the immune system and help our bodies fight infection. They circulate in the blood so that they can be transported to an area where an infection has developed. When the number of WBCs in your blood increases, this is a sign of an infection somewhere in your body. There are five main types of WBCs. They are: Neutrophils, Eosinophils, Basophils, Lymphocytes, and Monocytes. Neutrophils, eosinophils and basophils are also called granulocytes because they have granules in their cells that contain digestive enzymes.

• Red blood cells (RBCs), also known as erythrocytes, are by far the most abundant cells in the blood. RBCs give blood its characteristic red color. RBCs account for approximately 40 to 45 percent of the blood. This percentage of blood made up of RBCs is a frequently measured number and is called the hematocrit. The ratio of cells in normal blood is 600 RBCs for each white blood cell and 40 platelets.
