TEKS 7.12D) Differentiate between structure and function in plant an animal cell organelles including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast & vacuole
E) Compare the functions of a cell to the functions of organisms such as waste removal
F) Recognize that according to cell theory all organism are composed of cells and cell carry on similar functions such as extracting energy from food to sustain life
• The Cell Theory grew out of the work of many scientists and improvements in the microscope.
Scientists that contributed to the Cell Theory: Hooke: Leeuwenhoek: Schleiden: Schwann: Virchow:
• Early studies led to the development of the cell theory.
The Cell theory has three principles.1. All organisms are made up of cells2. All existing cells are produced by other living cells3. The cell is the most basic unit of lif e
Two Types of Cells
•Prokaryotic•Eukaryotic
Cells are the basic unit of lifeall living things share the following
characteristics:
• Growth• Response to environment• Reproduce• Get & use energy• Get rid of waste• Adapt to changes
There are two cell types: Prokaryotic cells and Eukaryotic cells.
All cells share certain characteristics.
1. All cells are enclosed by a membrane
2. All cells are fi lled with cytoplasm; a jellylike substance that holds things
