Introduction to Cells!

Recall the Cell Theory: All living things are made of one or more cells. All cells come from other cells. (Therefore, all living things come from other living things.)

Robert Hooke England (1665) Used a very simple microscope Looked at many things (feathers, fish, fly wings, fungi)

One day he looked at a slice of cork under his microscope. They reminded him of the little rooms where monks prayed. This is his actual drawing of what he saw. So what is Hooke remembered for?

At the same time, a man named Anton van Leeuwenhoek was also looking through a simple microscope. Holland (1673) He looked at blood from many animals. He also looked at pond water. Called them “animalcules”. How is his discovery different from Hooke’s?

So what ARE cells? many shapes many sizes many colors many different functions

Cells have many parts, but all cells have these three MAIN parts: cell membrane cytoplasm nucleus

The three main parts to a cell:
