6.3.1 Xylem and Phloem

• What is the main function of xylem in plants?

  Water and mineral transport
• Xylem tracheids are elongated, tapered cells that also transport water and minerals, but have thicker cell walls
• Match the xylem component with its function:

  Xylem Vessels ↔️ Upward transport of water and minerals

  Xylem Tracheids ↔️ Alternative transport pathway

  Xylem Parenchyma Cells ↔️ Structural support and storage
• Xylem ensures that plants have the resources needed for photosynthesis and structural integrity.


  True
• The structure of xylem allows continuous upward water flow in plants.


  True
• What is the primary function of xylem parenchyma cells?

  Structural support and storage
• Xylem vessels are hollow tubes that efficiently transport water and minerals
• Xylem parenchyma cells offer structural support and storage
• What is the primary function of phloem in plants?

  Sugar and nutrient transport
• What type of substances does phloem transport from the leaves to other parts of the plant?

  Sugars and nutrients
• Match the phloem component with its function:

  Sieve Tubes ↔️ Main transport pathway

  Companion Cells ↔️ Support and regulation

  Phloem Parenchyma ↔️ Structural support and storage
• What are xylem vessels?

  Hollow, tube-like structures
• The interconnected network of xylem tubes allows efficient water and nutrient transport in plants.


  True
• Why is xylem essential for plant growth?

  Water and nutrient transport
• What are the key components of xylem?

  Vessels, tracheids, parenchyma
• Xylem tracheids provide an alternative pathway for water and mineral transport, especially in plants with fewer xylem vessels
• What is the primary function of xylem in plants?

  Water and mineral transport
• What is the specialized structure that facilitates water and mineral transport in xylem?

  Xylem tissue
• Match the xylem component with its function:

  Xylem Vessels ↔️ Efficient water transport

  Xylem Tracheids ↔️ Alternative pathway

  Xylem Parenchyma ↔️ Structural support and storage
• Phloem transports nutrients and organic compounds downwards and laterally throughout the plant.


  True
• Companion cells provide support and regulate nutrient flow in sieve tubes.

  True
• The two-way transport system of xylem and phloem is crucial for the overall health and vitality
• Xylem is crucial for photosynthesis and plant structure
• Xylem transports water and minerals from the roots to the leaves.


  True
• Water transport by xylem is crucial for photosynthesis and transpiration.

  True
• Phloem is composed of sieve tubes and companion cells
• Sieve tubes in phloem are connected by perforated sieve plates
• Water and minerals are transported upwards from the roots to the leaves in xylem.

  True
• Xylem and phloem work together to support the plant's overall health and development.


  True
• Transpiration creates tension that pulls water upwards in the cohesion-tension theory.


  True
• What are xylem vessels?

  Hollow, tube-like structures
• Match the xylem component with its function:

  Xylem Vessels ↔️ Efficient upward transport of water

  Xylem Tracheids ↔️ Alternative pathway for water transport

  Xylem Parenchyma ↔️ Structural support and storage
• Osmotic pressure in phloem sieve tubes draws in water, causing the solution to flow.


  True
• Companion cells regulate the nutrient flow in sieve tubes.


  True
• Xylem and phloem work together as an integrated transport system to support the plant.
