Cells are similar to small factories with different laborers and departments that work all the time to make life possible. Various kinds of cells perform different functions like protein synthesis and energy production.There are two major kinds of living organisms based on their cellular structure namely: prokaryotes and eukaryotes.
- Prokaryotes are made up of cells with no nucleus. They all are single-celled microorganisms including archaea, bacteria and photosynthetic blue-green algae which are also known as cyanobacteria.
- Eukaryotes consists of cells with a nucleus. This large category involves all plants, fungi (such as molds, yeast, and mushrooms), protozoa (Plasmodium falciparum and parasite that cause malaria) and animals. The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cell and also responsible for cell to cell communication.

(a+b) ^2 means (a+b)*(a+b)
So (a+b)*(a+b)=a*(a+b) <i>+</i> b*(a+b)
On solving the brackets :
a*(a+b) <i>+</i> b*(a+b)
=(a*a) +(a*b) <i>+</i>(b*a) +(b*b)
=a^2 + ab <i>+</i> ba + b^2
=a^2 + 2ab + b^2
So, (a+b) ^2 = a^2 + 2ab + b^2

The ‘Green Revolution’ was introduced in India, in the late 1960s. Indian farmers used it for the production of major food crops like wheat and rice. They made use of the High Yielding Variety seeds, which produced much greater yield than the traditional seeds. However, they needed plenty of water, chemical fertilisers and pesticides to produce best results.
