World Of Microbes

WORLD OF MICROBES 

LET'S START WITH SOME FACTS

1. OUR BODY HAS 10-15 TRILLION CELLS. 
2. NEAR 90% OF THEM ARE BACTERIAL CELLS.
3. THERE ARE MORE MICROBES IN YOUR HAND THAN THE TOTAL POPULATION OF HUMANS IN EARTH.
4. MICROORGANISMS GENERATE HALF THE OXYGEN WE BREATHE.
5. THERE ARE MORE THAN 1000 DIFFERENT TYPES OF BACTERIA IN YOUR INTESTINE AND 205 DIFFERENT TYPES OF MICROORGANISMS IN OUR HAND.

 NOW LET'S TALK ABOUT THE TYPES OF MICROORGANISMS

• UNICELLULAR ORGANISMS: ORGANISMS WHICH IS MADE UP OF A SINGLE CELL IS KNOWN AS UNICELLULAR ORGANISMS.
• PROKARYOTE: PROKARYOTES ARE SINGLE-CELLED ORGANISMS WHICH LACK A MEMBRANE-BOUND NUCLEUS.

PROKARYOTE 

• EUKARYOTE: EUKARYOTES ARE ORGANISMS THAT HAVE WELL DEFINED NUCLEUS AND MEMBRANE BOUND ORGANELLES.

EUKARYOTE

• ARCHAEA: ARCHAEA WERE THE PRECURSORS OF LIFE ON EARTH.

ARCHAEA

• CYANOBACTERIA: CYANOBACTERIA WERE THE MICROORGANISMS WHICH INCREASED THE LEVEL OF OXYGEN ON EARTH FROM 0-10%.
