5 True/False Questions

1. chloroplast → a structure that are thought to be descendants of ancient prokaryotes b/c both contain some dnat

   True        False

2. hypotonic solution → solution which the concentration of awater is GREATER ON THE OUTSIDE the cell than inside the cell causes the cell to swell.

   True        False

3. dna → the energy molecule

   True        False

4. cytoskeleton → a network of protein filaments that helps the cell maintain its shap, involved in some cell movement and made of microtubules and microfilaments

   True        False

5. mitochondria → an example of a prokaryotic cell

   True        False
