Go to your CELL!

Today we looked at plants to see if we could find cells. There are three certain parts that every cell must have. One is the cell membrane. It protects the inside of the cell like skin. Another part is the nucleus. The nucleus is the brain of the cell. Cytoplasm is the third part. It's the liquid filling. For plants, the cells must also have a cell wall. Cell walls protect the plant from outside things. It's stronger than the cell membrane, it's thicker, too.
We made slides and looked for the different parts of a plant cell. We found them! When we first looked, we saw lots of cells piled together. Then when we looked closer we could make out the cell membranes and some of us could see the nucleus in a few. There were lots of cells.
It was really awesome and a little disgusting, too.
