You ever wonder what a cell is?
A cell is the smallest unit that can perform all of the processes necessary for life.
What did Theodor Schwann conclude?
All animal tissues were made of cells
Describe the cell theory.
1. All organisms are made of one or more cells.
2. The cell is the basic unit of all living things.
3. All cells come from existing cells.
The control center of the cell factory.
Nucleus.
Describe the vacuole?
A large vesicle in plant cells that store digestive enzymes, water, and other liquids.
Explain an organ system.
A group of organs working together to perform a specific function. An example is the cardiovascular system.
You ever wonder what the benefits to being multicellular are?
Larger size, longer life, and specialization.
