How can leafs exchange gases in the absence of light?
Light is necessary for the exchange of gases in plants.æ Light is what instigates photosynthesis and without photosythesis there can be no gas exchange.
When checking the efficiency of gas exchange it may be necessary to draw a blood sample from where?
Am artery
Why are transport systems necessary in multicellular plants and animals?
to maintain proper metabolism, mainly gas exchange
Gas exchange is also known as?
Gas exchange can also be referred to as respiration. This process involves the uptake of oxygen and release of carbon dioxide in living organisms. It occurs in specialized organs such as the lungs in mammals and gills in fish.
Why it is necessary for the lungs to have a dense capillary network?
Because it speeds up the gas exchange because it has a larger surface area.
Why is water always lost from the gas exchange surface?
Water is lost from the gas exchange surface of terrestrial organisms because gases must be exchanged with air. Terrestrial organisms have a high water potential, therefore when the gas exchange occurs water will be lost.
Is gas exchange a function of the digestive system?
Gas exchange is a function of respiration not digestion.
What is the elastic unit of the respiratory system where gas exchange occurs?
Alveoli is where gas exchange occurs.
What gas is released during germination process?
During the germination process, oxygen is absorbed by the seed and carbon dioxide is released as a byproduct of respiration. This gas exchange is necessary for energy production and growth in the germinating seed.
What do gas exchange systems have in common?
The exchange surfaces are moist.
What is the name for exchange of gas in the lungs?
gaseous exchange
Where does gas exchange occur?
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
