10 Questions
What is the main function of phloem vessels in plants?
Transport food (sugars) from leaves to all nongreen parts of the plant.
What is the role of companion cells in the phloem?
Companion cells help sieve tubes in loading and unloading of sugars.
Why are phloem vessels called sieve tubes?
They are named sieve tubes due to the presence of sieve plates at their ends.
What are the two main functions of the transport system in plants?
Transport of water and minerals absorbed by roots; Translocation of food from leaves to other plant parts.

What is the movement of water through the root tissue known as?
Ascent of sap or conduction of water through the stem to leaves.
Define transpiration in plants.
Transpiration is the movement of water through the plant tissue, specifically from roots to leaves.
What is the role of phloem fibers in the plant's transport system?
Phloem fibers provide mechanical strength to the phloem vessels.
How does the phloem parenchyma contribute to plant function?
Phloem parenchyma stores food within the plant.
What is the significance of the transport or conduction of water through the plant body?
