Introduction to Cells The Cell Theory Prokaryotic vs. Eukaryotic Animal vs. Plant Cells.

The Cell Theory All organisms are made up of one or more cells The smallest unit of life is a cell All cells come from pre-existing living cells. Remember: A theory is not a guess about how something works. An explanation acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation and also make predictions about phenomenon not yet observed.

Prokaryotic Cells Ancestral (primitive) Cells Very small Circular DNA Prokaryotic cells are going to be bacteria

Eukaryotic Cells More derived (advanced) cells. Larger than prokaryotic cells. DNA is stored in a membrane bound nucleus. Includes Protista, Fungi, Plants and Animals

Both Prokaryotic and Eukaryotic Cells have… DNA (prokaryotic is circular, while eukaryotic is a long strand) Cell Membranes made up of lipids Ribosomes- which are the site of protein synthesis. Cytoplasm- the jelly like substance in the within the cell.

Animal vs. Plant Cells Plant cells have Chloroplasts, Cell Walls and Central Vacuole while Animal cells do not
