The effect of light on seed germinationWhat is Transpiration?
The light-independant reactions of photosynthesis occur in the stroma of the chloroplast and involve the conversion of carbon dioxide and other compounds into glucose. The light-independent reactions can be split into three stages, these are carbon fixation, the reduction reactions and finally the regeneration of ribulose bisphosphate. Collectively these stages are known as the Calvin Cycle.
Effect of different colors of light on the rate of photosynthesis.
Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis.
Photophosphorylation is the production of ATP using the energy of sunlight. Photophosphorylation is made possible as a result of chemiosmosis. Chemiosmosis is the movement of ions across a selectively permeable membrane, down their concentration gradient. During photosynthesis, light is absorbed by chlorophyll molecules. Electrons within these molecules are then raised to a higher energy state. These electrons then travel through Photosystem II, a chain of electron carriers and Photosystem I. As the electrons travel through the chain of electron carriers, they release energy. This energy is used to pump hydrogen ions across the thylakoid membrane and into the space within the thylakoid. A concentration gradient of hydrogen ions forms within this space. These then move back across the thylakoid membrane, down their concentration gradient through ATP synthase. ATP synthase uses the energy released from the movement of hydrogen ions down their concentration gradient to synthesise ATP from ADP and inorganic phosphate.

how does temperature affect the rate of photosynthesis?
By: Jessica Perreault EX: Smog Acid rain Ozone depletion Greenhouse gases SMOG a combination of sulfur dioxide, ozone & other pollutants from burning fossil fuels - formed when a layer of cold air is trapped under a layer of warm air above it smog blocks out sunlight - chlorophyll in plants cannot access as much of the sun's energy to begin photosynthesis ACID RAIN any kind of precipitation with a pH of 5.7 or less it burns the tips of the leaves/needles, which are then shed.
what apparatus can you use to measure the speed of photosynthesis?
I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....

Leaves contain water which is necessary to convert light energy into glucose through photosynthesis. Leaves have two structures that minimize water loss, the cuticle and stomata. The cuticle is a waxy coating on the top and bottom of leaves which prevents water from evaporating into the atmosphere (Figure 3a).
