Plant Transport 1

Vascular Cylinder

A bundle of xylem and phloem surrounded by the endodermis at the center of roots and stems.

Endodermis

The innermost layer of cells in the root, providing a barrier to movement of water and dissolved substances into the vascular cylinder.

Osmosis

The movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Facilitated Diffusion

A process where substances move across a cell membrane with the help of transport proteins without the use of energy.

Active Transport

The movement of substances across a cell membrane against their concentration gradient, requiring energy from ATP.

Mineral uptake in plants

The process by which plants absorb essential minerals from the soil, often requiring energy to transport them into root cells.

Key Concept - Water and Minerals

Water follows the minerals in the process of absorption and transport within the plant.
