Plant Transport Flashcards

Flashcards covering transport in plants, including xylem, pholem, root hair cells, transpiration and translocation.

Xylem vessels __

Transport water & mineral ions from roots to leaves

Phloem vessels __

Transport sucrose & amino acids to roots & stem

Vascular bundles __

Are arranged throughout the root, stem & leaves in groups

Xylem adaptations: __

Cells joined end to end with no walls to form a continuous tube

Root hairs __

Single-celled extensions of epidermis cell in the root - grow between soil particles & absorb water&d mineral ions from the soil

Transpiration __

Loss of water vapour from plant leaves by evaporation

High temperature = more __

Occurs at a faster rate because particles have more Kinetic energy

Translocation __

The movement of sucrose & amino acids in the phloem

Source __

Part of plant releasing produced or stored Sucrose & amino acids by products of by plant Leaves as source in the summer

Sink __

Part of the plant using or storing sucrose and amino acids

What role do Xylem vessels play in plants?

Xylem vessels transport water and mineral ions from the roots to the leaves.

What do Phloem vessels transport?

Phloem vessels transport sucrose and amino acids from leaves to the roots and stem.

What are Vascular bundles?

Vascular bundles are arranged throughout the root, stem, and leaves in groups.

How are Xylem cells adapted for their function?

Xylem cells are joined end to end with no walls to form a continuous tube.

What are Root hairs and their function?

Root hairs are single-celled extensions of epidermis cells in the root that grow between soil particles to absorb water and mineral ions.

What is Transpiration?

Transpiration is the loss of water vapor from plant leaves by evaporation.

How does temperature affect transpiration rates?

Higher temperatures increase transpiration rates as particles have more kinetic energy.

What is Translocation in plants?

Translocation is the movement of sucrose and amino acids in the phloem.

What is a Source in plant biology?

The Source is the part of the plant releasing produced or stored sucrose and amino acids, typically during the summer.

What function does a Sink serve in a plant?

A Sink is the part of the plant using or storing sucrose and amino acids
