What is the function of the Xylem?

• Transport sugar
• Transport water
• Transport salt
• Turgor Pressure

Vegetables and Taproots store energy underground for plants. Vegetables and taproots are part of the plants ________ system.

• Photosynthesis
• Shoot
• Root 
• Hydrotropism

Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones to stimulate the growth of shoots.

How are gibberellins able to affect other parts of the plant?

• Gibberellins are absorbed through the stomata and attach to chloroplasts.

• Gibberellins are transported through vascular tissues to other parts of the plant.

• Gibberellins become concentrated within the tissues of the plant during mitosis.

• Gibberellins become modified once they infect healthy cells and are later released to infect other cells.

When the forces of cohesion and adhesion work together, water can move up the plant against the force of gravity by....

• Phototropism

• Geotropism

• Photosynthesis

• Capillary Action

Plant roots have extensions called root hairs. These root hairs. These root hairs are important in the homeostasis

of the plant.

Which statement best explains the importance of the root hair to the stems and leaves of the plant?

• Root hairs convert minerals into glucose for immediate use by cells.

• Root hairs decrease the need for osmosis and diffusion in vascular tissue.

• Root hairs prevent water loss in leaves through transportation and gas exchange.

• Root hairs increase the surface area of the roots for nutrient and water absorption.

Vascular tissue (tubes) responsible for the transportation of glucose down and around in a plant.

• Transpiration

• Xylem

• Phloem

• Root Hairs
