Essay: Choose TWO (2) of the following 4 questions to answer in COMPLETE SENTENCES. Clearly mark which
questions you are choosing to answer. An incomplete sentence is an incomplete answer. (5 points each)
Option 1. In Jakita’s Biology class she is asked to come up with an analogy for the selectively permeable nature of
the plasma membrane. She decides that a bouncer checking IDs at a club shows selective permeability. What is
selective permeability? Does Jakita’s analogy work? Why or why not?
Option 2. Why would a plant cell that transports water against the force of gravity contain many more mitochondria
than other plant cells?
Option 3. For the science fair project Daria wants to create a cell. She approaches her science teacher, Ms.
Moncrease, and asks if she can use her laboratory chemicals to make her cell. Ms. Moncrease informs Daria that
her project is impossible according to the Cell Theory. Why can’t Daria make a cell?
Option 4. When Ms. Moncrease taught the different parts of the cell and their jobs, Jose found himself relating
them to things in school. For example, the nucleus is the control center of the cell just like the principal is the
control center of the school. Help Jose expand his analogy. Compare three more cell parts to things at Wheeler.
