Prairie plants that live in dry climates and have large, underground root systems. How does this help them?

• The roots cool the plants off when they overheat.

• The roots manufacture water in times of drought.

• The roots help take in carbon dioxide for photosynthesis.

• The roots provide more surface area for the water absorption.

The main job of plant leaves is to:

• make food for the plant through photosynthesis
• keep the plant cool by making shade
• collect water for the plant when it rains
• help in the process of reproduction

What is the correct term that describes the tendency of a plant to grow towards lights?

• thigmotropism
• gravitropism
• hydrotropism
• phototropism

When a fly lands on a leaf of a Venus Fly Trap (Dionaea muscipula), the leaf closes. This is an example of -

• thigmotropism

• gravitropism

• hydrotropism

• phototropism

When a plant is left in a closed clear container, moisture can be observed inside the container. The water comes from –

• photosynthesis
• cellular respiration
• a decrease in phloem function
• a decrease in xylem function

In order for a plant to survive, why must its different systems interact?

• Because each individual system is specialized and cannot function on its own
• Because all of the different systems need to function independently
• Plants do not have separate systems therefore they cannot interact
• None of the above

Phloem delivers the sugar made during photosynthesis to various parts of a plant. Some food energy is converted into ATP for uses during plant activities such as phototropism. Which two plant systems are interacting in this scenario?

• Reproductive and response
• Transport and response
• Reproductive and transport
• No plant systems are interacting.
