carbon dioxide from the plant and the more yellow the solution is the more Carbon Dioxide there is. The greener or bluer it is, the less carbon dioxide.
They are Chloroplast things that help the plant.
An ELODEA cell is a PLANT cell. A HUMAN EPIDERMAIL cell is an ANIMAL cell. if you know that plant cells and animal cells have different organelles, then you should be good to go.
The green organelles found in the elodea leaves are called chloroplasts.
photosynthesis
It is a plant cell therefore it has a cell wall which animal cells do not. It also have chloroplast (makes it green, for photosythesis) and possibly vacuole.
The disk-like green structures within an Elodea cell are the chloroplasts.

chloroplasts
They are green because they contain a green photosynthetic pigment called chlorophyll.
