• Allows water movement from side to side

  Membenarkan

• Allows gaseous exchange for respiration in tracheid cell

• Path of organic materials from phloem to xylem

Which of the following is vascular tissue?

Diagram shows tissue X that is found in a plant stem.

What is the function of tissue X?

• Stores food as starch

• Transports the products of photosynthesis

• Transports water and mineral salts

• Provides support to plant

What happens when companion cell dies?

• Photosynthetic products cannot be transported by phloem

• Sieve tubes will collapse due to absence of support

• Photosynthesis cannot take place

• Function of phloem will be disrupted
