AP Biology Plant Vascular System

Plant Vascular System

Vascular system is the Roots and Shoots

• Roots: in the ground, absorb water and nutrients, and anchor the plant

• Shoots: everything above ground, the stem and leaves, do photosynthesis, and transport of food and water

Vascular system in Plants

• Help move materials around the plant

• Xylem transfers water and solutes from roots to leaves

• Xylem moves materials in only one direction from roots to leaves

• Phloem transfers glucose, amino acids, and hormones around the plant

• Phloem materials can move in either direction from roots to leaves or leaves to roots

Multiple Select

What does the xylem transport? (select all that apply)

• Water

• Glucose

• Minerals

• Amino Acids

Multiple Choice

Which direction do glucose and amino acids travel in the phloem?

• From roots to leaves

• From Leaves to roots

• Materials can be transported in either direction

Multiple Choice

What direction does water and solutes travel in the xylem?

• From roots to leaves

• From leaves to roots

• Materials can move in either direction

Roots

• Roots are a part of the plant vascular system

• Roots absorb water and solutes from the soil

• Root hairs increase the surface area of the roots which allows for greater absorption of materials

Multiple Choice

Are roots a part of the vascular system?

• Yes

• No

Multiple Choice

Why are root hairs important?

• They decrease the surface area of the roots to keep in water

• They increase the surface area of the roots to decrease absorption

• They increase the surface area of the roots to increase absorption

Transpiration

• The movement of water out of the leaves

• Helps pull water and solutes up from the roots into the leaves

Multiple Choice

In transpiration water leaves the plant through what structure?

• Leaves

• Roots

• Everywhere

Multiple Choice

What process does transpiration help the plant do?

• transport glucose and amino acids from roots to leaves

• transport water from leaves to roots

• transport water from roots to leaves
