Biology 12

Today we took notes on smooth and rough ER, Golgi Body, Vacuoles, Vessicles, and the secretory pathway to leave the cell.

We still have our lab on plants and animal cells to finish off, but we will leave that until tomorrow's double block.

We did a plant and animal cell coloring and matching sheet which is due tomorrow.  The Unit review is due on Friday as well as all the booklet questions.
