Antonie improved the microscope in the year 1674 and built single lens microscopes that could magnify 200x. Because they didnt have good measurment systems back them, Antonie would use visible objects such as grains of sand for size reference when looking at microscopic animalcules. He died in 1723. -
Carl Linneaus ( 1707- 1778 )
Mission 5 was about Carl Linneaus. Linneaus was sent on several journeys throughout Sweden to classify plants and animals.
