If you take a cross-section of a leaf and magnify it several times, you will see tiny pores on the underside. These holes are called stomata, and gaseous transfer takes place here, with carbon dioxide and oxygen entering and circulating inside the leaf. Waste gases from photosynthesis and respiration leave through the stomata as well. The oxygen diffuses out of the leaf because the concentration of oxygen is greater outside rather than inside the leaf (diffusion is the random movement of particles from an area of high concentration to an area of low concentration), down the concentration gradient. Likewise, the carbon dioxide diffuses into the cell because the concentration of carbon dioxide is greater outside the leaf than inside.
What else can I help you with?
What is the purpose of the leafs stomata?
To allow co2, h20 and o2 to move in and out of the leaf.
Which process in the leaf uses o2 and produces co2?
photosynthesis
What gases exit the stomata?
all gases in the air near the leaf/plant/tree will pass through the stomata. the exchange of CO2 and O2 happens inside...
What gases does a leaf give off in the Calvin cycle?
In the Calvin cycle, a leaf takes in carbon dioxide (CO2) from the atmosphere and gives off oxygen (O2) as a byproduct of photosynthesis.
When the CO2 concentration in the cells of a c3 plant is low compared with the o2 concentration an enzyme combines rubp with o2 rather than with CO2 what affect would this have on photosynthesis?
Since photosynthesis requires the carbon from CO2 and its not getting it, the entire process could come to a halt. This would usually occur in hot and dry conditions, where in higher temperatures, the enzyme has a higher affinity for binding to O2 than CO2.
What is the purpose of the leafs stomata?
To allow co2, h20 and o2 to move in and out of the leaf.
Which process in the leaf uses o2 and produces co2?
photosynthesis
What element supports all animal and plant life?
co2 and o2
CO2 enters and O2 escapes from a leaf via?
CO2 enters and O2 escapes from a leaf via small openings on the leaf's surface called stomata. Stomata regulate gas exchange and water loss in the plant through a process called transpiration. Carbon dioxide is taken in during photosynthesis, and oxygen is released as a byproduct of this process.
What element supports plant and animal life?
co2 and o2
What gases exit the stomata?
all gases in the air near the leaf/plant/tree will pass through the stomata. the exchange of CO2 and O2 happens inside...
How do O2 CO2 and H2O move into the lungs?
The gases get into your lung when you breathe.
How does CO2 get into a leaf?
Through the stomata, openings in the leaf surface. By diffusion. There are three photosynthesis processes, C3, C4, and CAM. (These names describe part of the chemistry.) The desert plants (and some epiphytes) use CAM, for in this process, the stomata are closed during the day, and open at night. The plant absorbs CO2 into its system as a complex chemical (the CAM bit) over night, and during the day, the stomata close and the plant converts the CAM chemical into CO2 to be used for photosynthesis in the usual way. Normal plants open their stomata during the day, and CO2 diffuses in and O2 out.
What gases does a leaf give off in the Calvin cycle?
In the Calvin cycle, a leaf takes in carbon dioxide (CO2) from the atmosphere and gives off oxygen (O2) as a byproduct of photosynthesis.
What do animals use to get oxygen to every plant?
what happens is we breath in o2 then we release carbon dioxide then the plants get co2 and release o2
What organelles take up CO2 and give off O2 in plant cells?
Chloroplasts are the organelles responsible for taking up CO2 and producing O2 in plant cells through the process of photosynthesis. Within the chloroplasts, the green pigment chlorophyll absorbs light energy to drive this reaction.
Where does water vapor exit and CO2 enter a leaf?
There are openings on the underside of a leaf called stomates. They have guard cells shaped like lips. They open and close to allow CO2 in and H2O and O2 out. It works using hydrostatic pressure.
