tugor pressure
turgor pressure, also turgidity, is the main pressure exerted by cell contents against the cell walls in plant cells
From the atmosphere surrounding the plant. Carbon dioxide diffuses in through the stomata of the leaves, which are openings controlled by cells called guard cells.
If the organelles called vacuoles are empty inside the plant cells, the cells will implode causing the plant to wilt.Further explanationPlant cells have many organelles out of which one is the vacuole that stores water.When the vacuole is filled with water, it pushes out and exerts an outward pressure against the cell wall and keeps the cells walls firm. This pressure is called the turgor pressure that keeps the plant stiff.When a plant is well-hydrated the vacuoles in a plant is filled with water, and the turgor pressure inside the cells is high, and this turgor pressure keeps the plant stiff. This stiffness helps the plant to stand straight (since they do not have any bone for support against gravity).When a plant gets dehydrated due to lack of water, the plant starts to use the water inside the vacuoles for its vital functions. So water inside the vacuoles starts to exit, and the vacuoles shrink in size.When water inside the vacuoles comes out the turgor pressure reduces thereby causing the plant to wilt.
When water leaves the plant cell, for example in osmosis, the pressure (created by the water) of the protoplast pushing against the cell wall will decrease. This pressure is known as turgor pressure and decreasing it will cause the cells to become soft/flaccid and so the plant will begin to wilt more and more as the turgor pressure decreases.

The pressure that builds in a plant cell as a result of osmosis is called turgor pressure.

Gas exchange for photosynthesis - CO2 from the air diffuses into the leaf, and 02 diffuses out of the leaf into the air
The Oppama manufacturing plant in Yokosuka, Japan.
Coal forms when dead plant material builds up and up to form peat, which is the first step. This is compacted between layers of sedimentary rock, forming a rock called lignite. Then this is compacted even more. Then, heat and pressure deep deep beneath the surface create anthracite, or coal. Coal is a metamorphic rock.
The mechanism that explains the movement of sugars throughout a plant is called the pressure-flow hypothesis
This is called turgor pressure.
A plant wilts when it has a decreased turgor pressure.
The cell wall is made up mostly of cellulose which, when formed into polymers, becomes stable. This allows the cell to have a greater pressure difference because the strength of the cell wall can keep more water in.
