Warm-up What does David Christian mean when he talks about Goldilocks conditions? Why are they important?

Endosymbiosis

Definition- The endosymbiotic theory describes how a large host cell and ingested bacteria could easily become dependent on one another for survival, resulting in a permanent relationship.

Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. Osmosis-

Gummy bear osmosis lab Set up lab note book- Each lab will have six sections- one for each step of the scientific method Procedure Hypothesis Materials Results Conclusion

Purpose- to observe osmosis in action by placing gummy bears in solutions of various solute concentrations We will place one gummy bear in a salt water solution and one gummy bear in tap water. We will also have a control gummy bear that will not be placed in water.

Hypothesis – Come up with one

Materials- gummy bears beakers water salt ruler scale

Procedures- Write as I explain

Give three points of evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.
