Grease a cookie sheet lightly with cooking spray. Roll sugar-cookie dough into a rectangular shape onto a cookie sheet and bake according to the packet instructions. Let the dough cool before continuing. This dough will represent the cell wall within the plant cell.
Smear chocolate pudding across the cookie dough. This pudding is representing the cell membrane so create a one-inch border between the pudding and the edge of the dough.
Cut four squares out of fruit roll-ups. Place the squares randomly on the cookie. This will represent the cytoplasm in the plant cell.
Take a round peppermint candy and place it in the center of the cookie. This is the nucleus.
Place two chocolate buttons on top of each roll-up square. This will represent the vacuoles within the cytoplasm.
Place green jellybeans around the cookie to represent chloroplasts and place red gummy candies on the cookie to represent mitochondria.
Create labels on small pieces of paper and tape each one to a toothpick. Place the toothpicks around the cookie to explain what each piece of candy represents. Once each part of the plant cell is explained, remove the toothpicks and quiz the kids on what each part is. When they successfully name the items, cut up the cookie and let them each have a piece.
