The three forces involved in the upward movement of water in plants?

Answer 1

Vascualr tissue is the tissue that allows water to move up in plants. However the main reason water is able to move up in plants is because of the cohesive and adhesive nature of water. Water has a tendency to cling to to other surfaces as well as itself. . This property of water is what makes it possible to plants to draw water up their roots and their shoots.

Answer 2

Fluid transport happens in the xylem tissue of the plant.

There are believed to be two mechanisms which transport water and nutrients from the roots to the tree top.

First is the evaporation of liquid from the leaves, this causes a negative pressure and water is drawn up the plant to replace it.

The second mechanism is that at the roots, by definition, the ion concentration outside the roots is greater than inside, so the osmosis forces water + ions into the roots.

Actually, in cool mornings, you'll actually see drops of liquid water on the edges of the leaves, water expelled from the leaves. This is known as guttation.

IF your question concerned the vertical growth of the plant, the plant responds to gravity. And the growing tip is organized as a spiral. Clockwise in some plants, and anticlockwise in others.

[Flanders & Swan had a song about the left-handed bindweed and the right-handed honeysuckle - maybe I got the hands wrong!]

These apical meristems are composed of undifferentiated tissue - their main job is progress. These are the guys that reach onwards.

Quite different apical meristems in roots and tips.

Answer 3

1. Water evaporates through the open stoma on leaves, creating a negative hydrostatic pressure that pulls water up through the xylem. This water is supported by adhesion (bonds to the side of the xylem) and cohesion (bonds with other water molecules)

2. Desiccation can occur at nighttime when positive pressure generated by water diffusing into the roots pushes the water columns in the xylem upwards.

Answer 4

The forces involved in the upward movement of water in plants are cohesion, adhesion, and transpiration pull. Cohesion refers to the attraction between water molecules, adhesion is the attraction between water molecules and the plant's vascular tissue, and transpiration pull is the force generated by water evaporating from the leaves, creating a negative pressure that pulls water up through the plant.

Answer 5

1) photosynthesis

2) Differentiation

3) Meristem

Answer 6

Odd, isn't that water can flow UP a tube into the top part of a plant and against gravity? This is due to capillary action and it is found in tiny tubes.

Answer 7

cohesion,adhesion,capillary action
