Transport, storage & gas exchange in flowering plants

Flashcards covering key vocabulary related to transport, storage, and gas exchange in flowering plants.

Autotrophic

Organisms that make their own food.

Plant metabolism

Reactions such as photosynthesis & respiration, and to reactions that occur in other processes such as cell division, growth & reproduction.

Root hairs

Extensions of root epidermis cells with thin walls not covered by a cuticle.

Osmosis

Absorption of water into root hairs.

Capillary water

Relatively pure water surrounding soil particles.

Root Pressure

Pressure from water drawn into roots by osmosis, pushing water up through the xylem.

Stomata

Openings on the underside of the leaf where most transpiration occurs.

Transpiration stream

The flow of water through a plant.

Cuticle

Waxy layer on leaves that prevents water loss.

Guard cells

Cells that surround the stomata and control their opening and closing.

Active transport

Process by which minerals are absorbed into roots using energy.

Ground tissue cells

Leaf tissue containing chloroplasts for photosynthesis.

Cohesion-Tension model+ Names

Model explaining how water is transported in plants to extreme heights against gravity.Dixen and Jolly

Cohesion

Sticking of similar molecules to each other.

Adhesion

Occurs when different molecules stick together.
