Photosynthesis – Plant Management in Florida Waters
photosynthesis A. sunlight is absorbed by chlorophyll in a leafB. carbon dioxide is taken in from the airC. water is transported from the rootsD. glucose is synthesized and distributed throughout the plantE. oxygen is released
The definition of photosynthesis is the process through which plants use water and carbon dioxide to create their food, grow and release excess oxygen into the air.
the plant organelle where photosynthesis takes place.
Summary of the different photosynthetic pathways. C3 plants fix CO2 directly, using the enzyme ribulose bisphosphate carboxylase oxygenase (Rubisco), reaction CO2 with ribulose bisphosphate (RuBP) to form PGA in the chloroplasts of the mesophyll. C4 plants react PEP carboxylase to react CO2 with phosphoenolpyruvate (PEP) to form oxaloacetic acid, which is in turn converted to malate. This is transferred to the bundle sheath, where malate is broken down to release CO2, which is used by Rubisco. CAM plants use PEP carboxylase to fix CO2 at night and then break down the malate so produced during the day to provide CO2 for Rubisco.
Models of Photosynthesis | Plant Physiology
The connection to hot and dry conditions comes from the fact that all the plants will close their stomata in hot and dry weather to conserve moisture, and the continuing fixation of carbon from the air drops the CO2 dramatically from the atmospheric concentration of nominally 380 ppm (2004 value). If the CO2 compensation point is lower on the above scale, the plant can operate in hotter and dryer conditions. The limits are placed by the fact that begins to fix oxygen rather than CO2, undoing the work of photosynthesis. C4 plants shield their rubisco from the oxygen, so can operate all the way down to essentially zero CO2 without the onset of photorespiration.

Printout A plant is a member of the kingdom Plantae, a living organism that utilizes photosynthesis, a process in which energy from sunlight is converted to chemical energy (food).
The Great Plant Escape: Photosynthesis
Nucleus: this contains genetic make (the DNA), which controls the activities of the cell.
Chlorophyll absorbs the light energy needed to make photosynthesis happen. It is important to note that not all the color wavelengths of light are absorbed. Plants mostly absorb red and blue wavelengths — they do not absorb light from the green range.
