Photosynthesis The leaves are the part of a plant where most photosynthesis takes place. If you cut a leaf in half and look at the cut end‚ it would look like this: Key: 1. Waxy cuticle: this gives the leaf a waterproof layer‚ which lets in light. 2. Upper epidermis: provides an upper surface. 3. Palisade cells: contain chloroplasts. 4. Spongy mesophyll: collection of damp‚ loosely packed cells. 5. Lower epidermis: layer of cells on the lower surface. 6. Air

time. In 1928‚ the Legislative Assembly of Alberta passed the Sexual Sterilization Act. In an effort to improve the human race and discontinue traits that were considered undesirable‚ the act allowed for the sterilization of specific individuals. It was widely believed that people suffering from mental illnesses and disorders had a much higher reproduction rate than the general population‚ and as a result the act was enacted to ensure the gene pool in Alberta would strengthen instead of

Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However‚ after reaching an intensity of 10‚000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may‚ in fact‚ slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100‚000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed

By decreasing the rate of accidents‚ preventing recklessness and carelessness on the roads‚ and lastly ensuring that all laws are obeyed when driving‚ may be a step towards the right direction of creating a safer community‚ and more manageable society. To decrease fatality and accident rates in Alberta‚ the age of obtaining a license should be raised. Service Alberta states

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

pigment solution (such as spinach and acetone) is exposed to different wavelengths of light to determine the points of the highest absorbance and transmittance percentages. (Hickey‚ Mary Kay). For this experiment‚ a Bausch and Lomb Spectrophotometer was used. Often objects appear colored because of their absorption of light within regions of the visible spectrum. The color of light we can see is composed of the wavelengths that the object did not absorb. Photosynthesis in plants takes place in

Consumption in Alberta In general it takes about 2 to 4.5 barrels of water‚ most of which is withdrawn from the Athabasca River‚ to produce one barrel of oil. While the amount of water consumed per barrel of oil produced has been declining‚ a 2006 Government of Alberta report warned that there simply may not be enough available water to meet the needs of all planned oil sands projects while maintaining adequate stream flows.
