The Cell

1. 2 The Cell • What do you think?

2. Different organisms have cells with different structures. All cells store genetic information in their nuclei. 2 The Cell • Do you agree or disagree?

3. 2 The Cell How are prokaryotic cells and eukaryotic cells similar, and how are they different? What do the structures in a cell do?

5. 2 The Cell Hooked Together? Look at the photo at the beginning of the lesson. What do you think happens when one of the hooks in the photo above goes through one of the loops? The two sides fasten together. The shapes of the hooks and loops in the hook-and-loop tape are suited to their function—to hold the two pieces together.

7. Do you agree or disagree? Different organisms have cells with different structures. 2 The Cell Agree. Two cells with two different functions will also have different structures.

8. Do you agree or disagree? All cells store genetic information in their nuclei. 2 The Cell Disagree. Prokaryotic cells do not have nuclei. DNA is located in the cytoplasm.

9. How are prokaryotic cells and eukaryotic cells similar, and how are they different? 2 The Cell A prokaryotic cell lacks a nucleus and other membrane-bound organelles, while a eukaryotic cell has a nucleus and other membrane-bound organelles.

10. What do the structures in a cell do? 2 The Cell Cell structures have specific functions, such as supporting a cell, moving a cell, controlling cell activities, processing energy, and transporting molecules.
