Cells Essential Question: What are cells and why is it important for us to understand cells?

How big are cells? Get a feel for the relative size of cells at – – How Big?

Cell Theory The Cell Theory states: All living things are made of cells. The cell is the smallest unit of life

Investigating Cells We divide cells into two groups depending on what internal structures they have. Cells can be either: – Prokaryotic, or – Eukaryotic Investigate your question for either Investigating Prokaryotes or Investigating Eukaryotes

Investigating Prokaryotes Questions 1.What is the basic definition of a prokaryotic cell? 2.What is the meaning of the word parts “pro-” and “karyo-” and how can these word meanings help you understand what a prokaryotic cell is? 3.What specialized structures, if any, are present in prokaryotic cells?

Investigating Prokaryotes Questions 4.What are examples of prokaryotic cells? 5.How do prokaryotic cells reproduce? 6.What are some ways that prokaryotic cells obtain energy?

Investigating Eukaryotes Questions 1.What is the basic definition of a eukaryotic cell? 2.What is the meaning of the word parts “eu-” and “karyo-” and how can these word meanings help you understand what a eukaryotic cell is? 3.What specialized structures, if any, are present in eukaryotic cells?

Investigating Eukaryotes Questions 4.What are examples of eukaryotic cells? 5.How do eukaryotic cells reproduce? 6.What are some ways that eukaryotic cells obtain energy?
