''Day 23'' - adding CO2 to tube 3 and the Erlenmeyer flask; checking the vessels: | |||
*Tube 1 - very high amount of Euglena (I didn't shoke the tube before taking a specimen this time. So I can be sure now that concentration is not even very high on the bottom but also in the whole tube.) | |||
*Tube 2 - high amount of Euglena; fast movement | |||
*Tube 3 - high amount of Euglena; fast movement | |||
*Tube 4 - high amount of Euglena; fast movement | |||

Note: The medium in the Erlenmeyer flask, the Beaker glass and tube 4 finally starts to become greenish. The cheese on the bottom is dark green but Euglena don't seem to concentrate on the bottom in those vessels. The reason why the organisms grow so fast now is maybe that they increase by splitting up theirselfes. That means that the multiplication would be exponential. | |||
The Paramecia disappeared completely. | |||
