The improvement of the microscope then led to an era during which many biologists made intensive observations of the microscopic structure of cells.

The inaccurate statements are:
- Warm, moist air goes up the mountain on its leeward side, where its water content condenses to precipitate as rain or snow;
- This side is called the windward side and, compared with the leeward side, receives hardly any rainfall;
In the description, the windward and the leeward sides of the mountain are mistaken, or rather have switched positions.
The windward side is the side where the warm, moist air where the water condensates and results in rainfall or snow. Thus this is the side of the mountain that is wetter and is covered with denser vegetation.
The leeward side is the side that doesn't receive warm and moist air, and the amount of precipitation is usually very low. This makes the leeward side very dry in most cases, and very often it is the reason for the formation of arid and semi-arid areas.
