Which structure in a plant cell allows the passage of oxygen to the environment?
The "stoma" is found in the outer layer of the leaf(epidemis), it allows the passage of oxygen to the environment. The plural of "stoma" is "stomata".
Which structure allows the passage of this oxygen to the environment in a plant cell?
The stomata, which are small openings on the surface of plant leaves, are responsible for allowing oxygen to move out of the plant and into the environment through a process called transpiration.
Which structure would toxins first enter the plant?
xylem
Which structure allows the passage of oxygen to the environment?
Stomata in plant leaves allow the exchange of gases with the environment. Oxygen passes out and carbon dioxide passes in. Stomata are holes in the leaf's surface layers , mostly on the underside of the leaves.
What structure allows a plant to reproduce without a water supply?
Cuticle.
What plant structure allows pollen to move through the style?
the stigma
What does a Cell wall mean in a plant?
it keeps the structure of the plant cell rigid and allows it to stay turgid
Can the size of plant populations be influenced by the molecular structure of available oxygen?
No it can't
A plant grows in soil contaminated with toxins . Through which structure would the toxins first enter the plant?
Xylem (Apex)
What allows the exchange of gases such as carbon dioxide and oxygen between plant and the atmosphere?
Stomata and lenticells
What structure allows the flow of gases in and out of a leaf?
Stomata are small openings or pores located on the surface of leaves that allow for the exchange of gases, such as carbon dioxide and oxygen, between the plant and its surroundings. These structures regulate the uptake of carbon dioxide for photosynthesis and the release of oxygen as a byproduct.
Where does oxygen and carbon dioxide enter and exit the plant during photosynthesis?
Carbon dioxide is a by-product of oxidative metabolism whereby sugars are broken down and their carbon molecules are transformed to C02 with the 02 coming from inhaled oxygen. Carbon dioxide leaves the body by diffusing from the tissue into the blood then leaving the body through the lungs.
