What Are Photosynthesis and Respiration?

A) Schematic representation of the gas exchange system LiCor. B) Basic equation for photosynthesis and transpiration. C) Light curve resulting from plotting rate of CO2 assimilation versus increasing light intensity (irradiance). Note that assimilation is first limited by the amount of light and then by the rate of carboxylation and recycling of the required precursors.

Respiration
Transpiration
This is the process that organisms (animals and plants) use to release energy stored in sugar.

The chemical energy stored in sugar is released when the bonds of the molecule are broken in the presence of oxygen.

•The leaf water potential was measured using the same leaf blade that the gas-exchange measurements were taken from with a pressure pump .

• The data were analyzed by regressions adjusted by the program Table CurveTM of AISN Software.

Method: Eucalptus saligna
Twelve Eucalyptus saligna seedlings were planted in April 2007 and grown for 2 years in 12 (10 m high) whole-tree chambers

They were planted 45 cm above the soil surface, on a installed floor surfaces.

The overall theme of the articles confirmed that there is indeed a compromising relationship between Photosynthesis and Transpiration, and that their rates are reliant several external and internal factors.

As plant chauvinists, understanding the physiological necessity for plant to photosynthesize efficiently for human food resource in agronomics and oxygen production for aerobic life respiration are relevant reasons for studying, investigating and exploring the photosynthesis-transpiration compromise.

Photo means light, synthesis means make; so photosynthesis means making from light

Plants take in carbon dioxide and water.

Plants are the only living organisms that can make their own food. This is one of the main ways of deciding if something is a plant.

facilitating both photosynthesis and respiration.

If plants could not turn the sun's energy into food, we would all die. That is because we can eat all sorts of things plants grow, such as leaves, seeds, fruits, roots, nuts and flowers. But we can't eat sunshine! Text

Photosynthesis, Respiration and transpiration

It is possible to determine rates of CO2 assimilation and water loss (transpiration) by measuring the flux of CO2 and water vapour from a leaf in a sealed chamber. This process, termed gas exchange (because CO2 is going in and water vapour is coming out) is more complicated than might be initially imagined. During photosynthesis, plants take up CO2 (which is converted to sugar) and produce oxygen. All the while they are respiring and releasing CO2 back into the cells. To make matters more complex, the enzyme that fixes CO2 (Rubisco) also ‘fixes’ oxygen, a reaction called photorespiration that releases CO2, but does not produce energy. Gas exchange is also influenced by light levels, because when more light is available, generally, more CO2 can be fixed.

How do respiration and transpiration differ? - Updated …



The plant gets its water from its roots in the soil and the carbon dioxide enters the leaves through the air (air is about .04% CO2).
Plants will grow in a certain direction as a reaction to outside conditions.
