Unit 10 - Plant Vascular System - Biology

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

• Water

• Glucose

• Minerals

• Amino Acids

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

What direction does water and solutes travel in the xylem?

• From roots to leaves

• From leaves to roots

• Materials can move in either direction

Are roots a part of the vascular system?

• Yes

• No

Why would increased stomatal density be beneficial to a plant?

• more carbon dioxide absorption
• more oxygen absorption
• more water loss
• more sunlight absorbed

The main function of stomata is to

• capture sunlight

• protect leaves from insects

• allow gases to move rapidly in/out of leaves

• release sugars into the atmosphere

What is the relationship between stomata and photosynthesis in plants?

• The stomata is dependent on photosynthesis.

• The stomata are reactants of photosynthesis.

• Photosynthesis is dependent on stomata.

• Photosynthesis is independent of stomata.

Which gas is removed from the atmosphere during photosynthesis?

• hydrogen
• oxygen
• nitrogen
• carbon dioxide

What are the products of photosynthesis?

• water and carbon dioxide
• oxygen and glucose
• oxygen and carbon dioxide
• oxygen and water

Which organelle from the plant cell is primarily responsible for converting sunlight to energy?

• Mitochonria
• Nucleus
• Vacuole
• Chloroplast
