what is the function of xylem tissue?

• transports water and minerals salt 
• control the opening and closing of stoma
• carry out photosynthesis
• provide support for young plant

• support plants
• photosynthesis process occur
• transport organic nutrients

Which of the following structures allows for gas exchange between a leaf and the atmosphere?

• Cuticle
• Phloem
• Stomata
• Xylem

Sieve tubes and companion cells are present in

• xylem

• phloem

• cambium

• cork

The main function of a xylem cell is

• To transport nutrients (mainly sucrose) to different parts of a plant.

• To make energy for the plant via photosynthesis.

• To transport carbon dioxide to the leaves for photosynthessis.

• To transport water to different parts of plant.
