Hydrogen bonds between water molecules create cohesion, allowing water to be pulled up through the xylem tissue of a tree. Adhesion between water molecules and the xylem tissue walls helps to counter gravity and support this upward movement of water. Transpiration, the evaporation of water from the leaves, also creates a negative pressure that assists in drawing water up the tree.
What else can I help you with?
What carries the sap from the roots up the trunk?
The xylem tissue in a plant carries sap from the roots to the leaves through a process called transpiration. Water and nutrients are absorbed by the roots and then pulled up through the xylem vessels by evaporation of water from the leaves.
What theory explains how water is moved from roots to leaves?
The cohesion-tension theory explains how water is moved from roots to leaves in plants. This theory suggests that water is pulled up through the plant by the cohesive forces between water molecules and the tension generated by transpiration in the leaves. This creates a continuous water column that is pulled up through the xylem.
Do leaves permit entry of carbon dioxide and roots permit entry of water?
No, leaves primarily allow for the entry of carbon dioxide through tiny openings called stomata while roots primarily absorb water and minerals from the soil. Leaves play a role in gas exchange for photosynthesis, while roots are responsible for water and nutrient uptake.
What type of leaves does tap roots have?
A tap root does not have leaves... it is underground.
Are roots or leaves more important to a plant?
Roots and leaves are equally important to a plant. Without either one, it dies.

How do pines adapt to rivers?
Pines have special kind of roots that allow them to store water and their leaves to withold the water that's why they have longer leaves
What are leaves roots and stems?
leaves roots and stems are part of a tree
How do succulent leaves grow roots to propagate new plants?
Succulent leaves grow roots to propagate new plants through a process called propagation. When a leaf is removed from the parent plant and placed in soil, it can develop roots from the base of the leaf. These roots allow the leaf to absorb water and nutrients, eventually forming a new plant.
Where photosynthesis happen in plants?
Photosynthesis occurs in the leaves of plants. The leaves allow CO2 to come in through the leaves. The sunlight turns the water that comes in from the roots through the stem into the leaves to make a chemical change in the H2O and CO2 into sugar.
What forms from organic matters such as leaves and roots?
Litter forms from organic matter such as leaves and roots.
What adaptations allow arctic willows to survive in the tundra?
Short roots can thrive in the shallow layer of soil above permafrost. With long roots, their roots cannot grow through the permafrost and the plant will fall over.
Do leaves permit entry of carbon dioxide and roots permit entry of water?
No, leaves primarily allow for the entry of carbon dioxide through tiny openings called stomata while roots primarily absorb water and minerals from the soil. Leaves play a role in gas exchange for photosynthesis, while roots are responsible for water and nutrient uptake.
Side effects of dried cassia roots and leaves?

Are stomas found on the underside of the roots or leaves?

How do you make a sentence with the word roots?
I pulled up some roots from the garden last weekend.
