Transport in Plants

Front

Describe water transport in plants

Back

Water is absorbed by roots, travels through the plant, and evaporates from the leaf surface.

Front

Transpiration

Back

The process that provides the main force which brings water from the soil and through the plant, involving water loss where water vapor escapes from the leaves.

Front

Suction in Transpiration

Back

As water evaporates from the leaves, it creates a type of "suction" that pulls water up the stem.

Front

Transpiration Stream

Back

The flow of water up the vessels within the vascular bundle.

Front

Turgor Pressure in Leaves

Back

Within the leaf, cell sap exerts turgor pressure outwards on the cell wall, forcing some water out of the cell wall and into the air space between the cells.

Front

Water Vapor Diffusion

Back

Water vapor passes via diffusion through the air spaces in the mesophyll and out of the stomata.

Diagram of leaf structure

Back

Illustrates the structure of a leaf, including cuticle, upper and lower epidermis cells, palisade and spongy mesophyll cells, and stomata.

Front

Transpiration process involves water loss from cell walls, which is replaced by drawing water from xylem vessels in the nearest vein.

Back

As a result of water loss, water is pulled through the xylem vessels and up the stem from the roots.

Front

Water movement in cells involves not only passing along cell walls but also through the cells.

Back

As the cell loses water, turgor pressure falls, causing water in the cell wall to enter the vacuole and restore turgor pressure.
