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.

Two cells that regulate the size of the stomata depending on temperature and

water conditions

• Phloem

• Xylem

• Stomata

• Guard Cells

A large number of elongated cells that

grow out from the roots. They absorb water and minerals from the soil

via osmosis.
