Introduction - The cells that make up our body are so small that you could fit over 200 of them on the full stop at the end of this sentence Before we plunge into the chapter, here are some interesting facts about cells. Read on... The word cell is derived from the Latin word cellula whic..

The units of all physical quantities can be derived from the seven basic units. These units are called derived units because they can be derived from the basic units algebraically by multiplication and division. It is f..

Question 1 - Question: Why were the scientists not able to observe most of the cell organelles before 1940? Answer: Before 1940, scientists could view the cell only under a light microscope. The invention of the electron microscope in 1940 enabled the scientists to observe the cell in greater detai..

The simplest structural units into which a complex multicellular organism can be divided and still retain the functional characteristic of life, are called cells. One of the unifying generalisations of biology is that certain fundamental activities are common to almost all cells..

Organisms may be broadly classified into two kinds: Unicellular Multicellul..

The value of any physical quantity is always expressed as its numerical value as well as a unit. One often hears the weight expressed as grams or kilograms; the distance as foot, yard or mile; the volume as litres or gallons. The use of a number of units cause confusion and comp..
