Chapter 18.1 Opener

Front

What happens to the number of stomata in leaves during higher temperatures?

Back

Leaves will have fewer stomata.

Front

What type of plant has a system of tubes to carry water and nutrients?

Back

Vascular plant.

Front

How does water move through the xylem?

Back

Through capillary action and transpiration.

Front

What is the main function of stomata in plant leaves?

Back

Transpiration.

Front

What is the primary function of root hairs in plants?

Back

Water absorption.

Front

Define vascular plants.

Back

Plants that have a system of tubes (xylem and phloem) to transport water and nutrients.

Front

What is transpiration in plants?

Back

The process of water vapor loss from plant leaves through stomata.

Front

What role do stomata play in photosynthesis?

Back

They allow carbon dioxide to enter the leaf for photosynthesis.

Front

What is the difference between vascular and nonvascular plants?

Back

Vascular plants have specialized tissues for transport; nonvascular plants do not.

Front

Explain capillary action in plants.

Back

The ability of water to move through narrow spaces in the xylem due to adhesion and cohesion.
