Points of ponder

1- Chloroplast is only on plant cells. It captures the energy from the sun light. There are many of them in a plant cell it is green and it is more less round.
2- the guard cell is two cells stuck together and the stoma is when water and air comes in they open up.
3- In the elodea cell I could see better the cell wall also there were less chloroplasts.  The lettuce cell was harder to see and there were many guard cells.
4- what I have found is that they  all have chloroplast, cell wall and all cell membrane and it looks green.
