vascular system of plants

anchor plants in the ground and prevents erosion

• roots

• stems

• leaves

defense system that protects the plant against predators and disease (thorns, waxy coating)

• roots

• stems

• leaves

carry the products of photosynthesis from the leaves back down to the roots

• roots

• stems

• leaves

Which of the following is NOT a function of the roots?

• Store sugars

• Absorb water and minerals

• Anchor plant to the ground

• Photosynthesis

What is the vascular tissue that carries water throughout a plant?

• phloem

• seedling

• xylem

_____________________ is a vascular tissue that carries sugars and other foods throughout a plant.

• stems

• phloem

• roots

• xylem

Vascular tissue not only transports material it also

•  protects the plant
• supports the plant structurally
• transports minerals
• transports energy

Recall what the pathway of water from roots to leaves is called.

• Respiration

• Translocation

• Transpiration stream

• Evaporation

Select which of the following statements are true for phloem.

• Bi-directional movement (up and down stem).

• Elongated, tubular shape with thin walled sieve tubes.

• Transportation of feed and nutrients.

• Occupy the centre of the vascular bundle.

• Water and mineral transport from roots to aerial parts of the plant.

Select which of the following statements are true for xylem.

• Tubular shape with no cross walls.

• Transportation of food and nutrients.

• Elongated, tubular shape with thin walled sieve tubes.

• Occupy the center of the vascular bundle.

• Water and mineral transport from roots to aerial parts of the plant.
