A process that illustrates a feedback mechanism in plants is when the guard cells change the size of a leaf's openings to control gas exchange. Guard cells are located in the epidermis of leaves.

What is the mechanism of water movement through the xylem?
transpiration is the process that moves substances through the xylem
The association of plants and fungi in mycorrhizae illustrates a type of relationship called?
Mutualism.
What is the refference of why is it that only plants can photosynthesize?
As well as plants, some bacteria also photosynthesize, though they use a different chemical process. Some plants use different photosynthetic mechanisms, known as C3, C4, and CAM. The latter mechanism is used by plants (such as some 'perching plants') that may have a water conservation problem. These plants open their stomata at night to take in CO2, and dissolve that in a specific chemical. During the day, they close their stomata to conserve water, and process the stored CO2 to produce sugars, etc.
How is photosynthesis a constructing process?
It is used as a food making process for plants. It "constructs" food for plants that is why its a constructing process.
Cattail plants in freshwater swamps are being replaced by purple loosestrife plants The two species have very similar environmental requirements This observation best illustrates?
4. competition between species
When dry environmental conditions exist guard cells reduce water loss from plants by closing the openings in their leaves This process is an example of a feedback mechanism that plants use in order?
maintain homeostasis.
What process do plants absorb minerals?
Diffusion,ion exchange and mass exchange is the mechanism of active absorption of minerals in plants.
What is the mechanism of water movement through the xylem?
transpiration is the process that moves substances through the xylem
What seeds are dispersed by mechanism?
plants
How does water loss from stomata help to cool plants?
the process is know as evaporative cooling through transpiration. the mechanism is similar to how humans are cooled through sweating
Why plants don't need salty water?
The salt water having greater osmotic potential than that of cell sap may obstruct in the process of absorption of water by plants. However, plants growing as mangrove vegetation or marine plants have developed the mechanism of eliminating salts from their bodies.
The association of plants and fungi in mycorrhizae illustrates a type of relationship called?
Mutualism.
What do All plants and animals have mechanism that?
Transport Nutrients
How do castor plants disperse their seeds?
by explosive mechanism
Is cork produced by plants of animals?
It comes from plants, it is a kind of defence mechanism like sap
What is the life process of plants?
Biology is the life process of plants.
A storm kills many plants at random is which mechanism?
gene flor
