Who was the first to observe and describe cells, by noting that the cells in a wine cork resembles the living quarters of monks or prisoners?

This was Scientist Hooke... he was once in jail and that may have been one of the reasons he made the connection to the cells shape and called them what they are today :)

lol we just learned this biology earlier this week and I'm so proud of myself that I remember :)

The correct answer is Robert Hooke.  

The invention of the microscope is one of the most essential discoveries ever made by the scientists. Robert Hooke in 1965, witnessed a slice of thin cork beneath the microscope and witnessed minute spaces, which appeared like small rooms combined together.  

As they appeared like the tiny quarter of prisoners or monk he named the structures as cells.  

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
