II. Looking inside the Cell

ACTIVITY: WORKING IN GROUPS OF 3

Create a set of notecards to help study cell organelles. You will need to make 4 cards for each organelle.

1. Organelle Name Card2. Function Card3. Structure Card4. Sketch Card

When you are finished. Mix the cards up on the table and practice matching organelles with function, structure, and sketch.
