Robert Hooke's discovery of the cell.
In 1665, Robert Hooke looked at cork through a microscope and saw empty spaces resembling honeycomb compartments or monk cells, coining the term 'cell'! Soon after in the 1660s, Antonie van Leeuwenhoek used improved lenses to discover living bacteria, earning him the title 'Father of Microbiology'.
How lenses changed biology.
Long ago, people noticed that a curved piece of glass could make small things look bigger. Because this glass was shaped like a lentil seed—thick in the middle and thin at the edges—they called it a lens.
Over time, lenses were improved to become more powerful, evolving into early microscopes.
Test knowledge of Hooke and Leeuwenhoek.
In 1665, a scientist named Robert Hooke published detailed drawings of tiny things in a book called . Using a microscope, he looked at a thin slice of and noticed it was made of many small, empty spaces.
Because these compartments reminded him of a honeycomb, he called each small space a .
Around the same time, a Dutch scientist named Antonie van made better lenses that allowed him to build more useful microscopes. Because he was the first person to clearly see and describe tiny living things like bacteria, he is known as the Father of .
Core organelles of plant and animal cells.
All basic cells share three main components that keep them alive and functioning:
Diagram of plant and animal cell components.
Both plant and animal cells have a nucleus, cytoplasm, and cell membrane.
Plant cells also have:
Animal cells usually do not have these parts.
