Now it became common to pitch the ball through the air, rather than giving underarm bowling. This change gave bowlers the option of length, deception through air and increased pace.

All living organisms are made up of cells. Thus, cell is the structural unit of life. Each living cell has the capacity to perform certain basic functions that are characteristics of all living forms. Each cell acquired distinct structure and function due to the organization of its membrane and cytoplasmic organelles in specific way. Each kind of cell organelle performs a special function, such as making new materials in the cell (e.g., chloroplast, ribosomes), clearing up the waste materials from the cells (e.g., lysosomes), utilisation of oxygen in oxidation of food and energy production (e.g., mitochondria), movement (microtubules containing spindle, cilia, flagella), etc. A cell is able to live and perform all its functions because of these organelles. These organelles together constitute the basic unit of structure and function called the cell.
Robert Hooke in 1665 discovered the cells. He examined a thin slice of cork under a self-designed crude microscope and observed that the cork resembled the structure of a honey comb. The latter consisted of many tiny compartments. Hooke called them cellulae (singular cellula), now termed cells. CellRead more

Such rooms were also present in monastries.
