LESSON #1What is so extraordinary about the organization of living organisms?
Prof. Beatriz Duro SEK Ciudalcampo International School
How large are things really? Microscopic objects are
meassured in: μm = 10-3 mm Nm = 10-6 mm
(1000 μm =1mm) Not visible with a naked
eye. Eye resolution is 0,2 mm
If two objects are separated by a smaller distance, we will see them as one.
Exercise 1: If an object meassures 1 mm, how many micrometers does it meassure? And how many nanometers?
Exercise 2: Calculating sizes
Paramecium caudatum magnified 300 times
3.6 cm
What is the size of the paramecium? Could we see it with our naked eye?
