NOTES FROM MR.ANDERSON’S WATER POTENTIAL VIDEO (SAVES TIME AND EFFORT!) Water potential is the potential energy of water per unit area compared to pure water. Which allows you to figure out where water’s going to flow due to osmosis‚ gravity‚ pressure and even surface tension. It also allows you to figure out if water will flow in the first place and if it will flow into the cell or not. Water Potential (symbol psi) = Solute Potential (symbol psi s) + Pressure Potential (symbol psi p) Solute

Answers to Photosynthesis Practice AP Biology 1. Draw a picture of the chloroplast and label the stroma‚ thylakoid‚ thylakoid lumen (space)‚ inner membrane‚ outer membrane. 2. Using 18O as the basis of your discussion‚ explain how we know that the oxygen released in photosynthesis comes from water. When the oxygen in water has the radioactively labeled oxygen‚ the gas released from photosynthesis also has the labeled oxygen. This shows that the oxygen gas given off during photosynthesis comes from

product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems2. Many organisms are not able to use the energy obtained from sunlight directly; however‚ plants are able to use this energy and convert it into chemical energy by converting CO2 (carbon dioxide) and H2O (water) to organic materials3. The energy source for photosynthesis comes from sunlight‚ which allows for the fuel that drives photosynthesis. This process

use a process called photosynthesis to covert energy from the sun into energy they can use for their activities. The plant’s chloroplasts‚ along with water‚ carbon dioxide‚ and light are the essential elements required for photosynthesis to take place. The “photo” part of photosynthesis is in reference to the fact that the process requires light. The simplest form of the photosynthesis equation is: H2O + CO2 ----light----> (CH2O)N + O2 As shown in the equation‚ photosynthesis produces carbohydrates
