Water and Nutrient Transport in Plants

This set of flashcards covers key concepts related to the transport of water and nutrients in plants, including the structures and theories involved.

Bulk Flow

Water movement under the influence of pressure and gravity.

Xylem

Tissue adapted for long-distance transport of water and minerals.

Tracheids

Type of tracheary element in xylem tissue that helps in water transport.

Vessels

Structures in xylem composed of vessel elements that facilitate efficient water transport.

Cohesion-tension Theory

Explains the role of transpiration and the physical properties of water in long-distance transport.

Transpiration

The process of water movement through a plant and its evaporation from aerial parts, especially leaves.

Guard Cells

Cells that control the opening and closing of stomata to reduce water loss.

Phloem

Tissue responsible for the long-distance transport of organic molecules.

Sieve-tube elements

Components of the phloem that transport sugars and other organic substances.

Sieve plates

Structures that separate sieve-tube elements and have pores for transport.

P protein

Protein found in the phloem that helps in wound response.
