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.

What does stoma allow to enter the leaf?

Stomata allow carbon dioxide to enter the leaf for photosynthesis, while also allowing oxygen and water vapor to exit the leaf through transpiration.

What is the escaping of water vapor from the leaf?

when water vapor escapes from a leaf, it is called transpiration.


What does stomata on a leaf allow to enter the leaf?

Stomata are small openings on the surface of leaves that allow gases to enter and exit the leaf. They primarily facilitate the intake of carbon dioxide for photosynthesis while also enabling the release of oxygen and water vapor. This gas exchange is essential for the plant's growth and respiration processes. Additionally, the regulation of stomatal openings helps maintain water balance within the plant.


Can air enter and exit a leaf?

What allows water vapor into and out of a leaf?

Water vapor enters and exits a leaf through small openings called stomata, which are located on the surface of the leaf. When the stomata are open, water vapor can diffuse in and out of the leaf, allowing for gas exchange and regulating the leaf's internal water content.


What is the whole between two guard cells in a leaf called?

It's called a stoma (plural stomata) and its function is to allow carbon dioxide to enter the leaf for photosynthesis. The guard cells sre responsible for regulating the size of the stoma.


What it the escaping of water vapor from a leaf?

What is an adaptation of a leaf for photosynthesis?

The leaf has a wide range of pores which allow Carbon Dioxide to enter and Oxygen to exit.


What substances pass through a leafs stomata?

Water vapor, oxygen, and carbon dioxide pass through a leaf's stomata. Water vapor exits the leaf during transpiration, while carbon dioxide enters the leaf for photosynthesis. Oxygen is a byproduct of photosynthesis and is released from the leaf.


How gases enter and exit a leaf?

Gases enter and exit a leaf through stomata. These are openings in the epidermis which are regulated by guard cells. Guard cells decide which gases can go in and out. The gas that goes in is carbon dioxide and the gas that goes out it oxygen.
