Osmosis and Water Potential (Updated)

Explore the process of osmosis in this updated Amoeba Sisters video! Video features real life examples of osmosis, important vocab, and introduces concept of water potential and turgor pressure in plant cells. Expand details for table of contents. We have an Unlectured resource on this topic! https://www.amoebasisters.com/unlectured

We are so appreciative of feedback we receive as it helps us continue to improve. In this video, we say the word "molecules" several times. Chemically speaking---the term "molecule" may be ok when referring to water but not salt as we did in 2:54. Salt is formed by ionic bonds [not molecular (covalent) bonds like you would see in water].

Vocabulary includes solute, solvent, passive transport, hypertonic, hypotonic, isotonic, equilibrium, water potential, pressure potential, turgor pressure, and solute potential.

NOTE: We defined water potential as potential energy in water (supported in reference: https://cnx.org/contents/bDIuMp-w@7.1..., but in the video, we do note that this definition can be expanded upon or worded in many different ways. In bio specifically, water potential tends to be used to describe where water travels based on solute potential and pressure potential.
