Where in a leaf does photosynthesis take place?
Photosynthesis takes place in the chloroplasts of a leaf, specifically in the cells of the mesophyll layer.
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.
In which blood vessels does oxygen exchange take place?
Oxygen exchange takes place in the capillaries, which are the smallest blood vessels in the body.
How does the body get rid of gaseous waste?
Gaseous waste is expelled from the body primarily through respiration. A process called gas exchange takes place in the lungs. With every breath we take, some quantity of the waste gases (like carbon dioxide, or CO2) in our blood is exchanged for oxygen (O2) in the air inspired. Note that anything else in the air that we inhale can be carried across and into the blood.
What is the purpose of air spaces in the spongy layer?
Air spaces in the spongy layer of a leaf facilitate gas exchange by allowing for the movement of oxygen and carbon dioxide between the leaf cells and the external environment. This helps in photosynthesis by providing a pathway for carbon dioxide to reach the chloroplasts and for oxygen to exit the leaf during respiration.
Where does gaseous exchange take place in a leaf'?
stomata
Where in the lungs does gaseous exchange take place?
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
Where do the gaseous exchange take place?
Respirtary system, lungs, also known as thoratic region
What part of leaf where exchange of gases take place?
The exchange of gases in a leaf primarily occurs in the mesophyll cells, which are located in the interior layers of the leaf. The stomata, small openings on the surface of the leaf, also play a crucial role in gas exchange by allowing carbon dioxide to enter and oxygen to exit the leaf.
What is the stomata on a leaf?
The opening (usually on the underside of a leaf) that allows gas exchange to take place which is essential for respiration but which also looses water.
Where does gaseous exchange take place and which two gases are involved?
Gaseous exchange takes place in the lungs, specifically in the alveoli. Oxygen from inhaled air diffuses into the bloodstream, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled.
Why are sponge lungs better than hollow lungs?
Because they have a greater surface area over which gaseous exchange can take place.
Where does gaseous exchange in human take place?
Gaseous exchange in humans takes place in the alveoli of the lungs. Oxygen from inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
Why does diffusion takes place in the leaf?
Diffusion occurs in the leaf to facilitate the movement of gases such as carbon dioxide and oxygen. These gases diffuse in and out of the leaf through small openings called stomata, allowing for photosynthesis and respiration processes to take place effectively. This exchange of gases helps the leaf to obtain the necessary substances for energy production and to release waste products.
How does gaseous exchange take place in Amoeba?
Gaseous exchange in Amoeba occurs through diffusion. Oxygen from the surrounding environment diffuses into the cell across the cell membrane, while carbon dioxide produced by cellular respiration diffuses out of the cell. This process allows for the exchange of gases to support the metabolic activities of the cell.
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.
Where does the gaseous transfer take place in a frog?
by the skin
