Gaseous exchange occurs in plants through these structures in the epidermis?
stomata
What is the mechanism of material exchange at the capillaries?
Gaseous exchange happens through diffusion.
Where in the body apart from the lungs does gaseous exchange occurs?
Gaseous exchange occurs through capillaries all over the body to bring oxygen to cells and remove carbon dioxide.
Where do plants get there oxygen?
approx 80% is taken in through their root system the rest through gaseous exchange.
Does seaweed breathe?
Seaweed does not breathe, instead it respires by gaseous exchange through water
What is the function of a leafs stomata?
Help in gaseous exchange
What is 'gaseous exchange'?
Gaseous exchange is the movement of oxygen in the body, it takes place in the lungs through diffusion by the alveolar surface. There are millions of alveloi in the lungs, which gives it around 70m2 of exchange surface.
How does gaseous exchange take place in the lower plants?
In lower plants such as mosses and liverworts, gaseous exchange occurs through simple diffusion across the cell membranes. These plants lack specialized structures like stomata found in higher plants, so gases enter and exit the plant cells directly through their surfaces. This process is limited by the surface area available for exchange, making lower plants reliant on moist environments for efficient gaseous exchange.
What plays a role in gas exchange?
haemoglobin present in the RBC helps in gaseous exchange and transport in humans .. where as in plants its through stomata , cuticle , lenticels etc....
Why is Transpiration is the inevitable consequence of gaseous exchange in land plants?
Transpiration is the inevitable consequence of gaseous exchange in land plants because it is the process by which plants lose water vapor through their leaves while exchanging gases with the atmosphere. As plants take in carbon dioxide for photosynthesis through their stomata, water vapor is released. This helps maintain the plant's internal water balance and allows the exchange of gases necessary for photosynthesis and respiration.
What is the respiratory organ of earthworms?
The earthworm has no special respiratory organs. Gaseous exchange occurs through moist skin by diifusion.
Why tissues involved in gaseous exchange are always moist?
If they dried out they would no longer be able to let gasses pass through them.
