The Cell THE BASIC STRUCTURE THAT MAKES UP

The Cell THE BASIC STRUCTURE THAT MAKES UP ALL LIVING ORGANISMS

The Discovery of the Cell �The cell is the basic unit of structure and function of all living things. The structures that make up a cell are called organelles. � 1665: Robert Hooke looked at cork he saw "little rooms" that he called cells

Understanding Cells �Anton van Leeuwenhoek Used a simple microscope to see moving objects that he called "animalcules. " He was actually looking at bacteria. �Matthius Schleiden Botanist who studied the parts of plant cells. Determined that all plants are made of cells �Theodore Schwann: Zoologist who studied animals. Determined that all animals are made of cells �Rudolf Virchow: All living cells come from other living cells.

The Cell Theory 1. All living things are made of cells 2. Cells only come from other living cells. 3. Living cells are the basic unit of structure for all living things.
