Option 1 is the correct statement. Xylem is a complex tissue in plants that is responsible for transporting water and minerals from the roots to other parts of the plant. It consists of several cell types, including tracheids, vessels, xylem parenchyma, and xylem fibers.

Tracheids and vessels are long, tube-like cells that transport water and minerals upwards in the plant. They are characterized by having thick, lignified cell walls which provide strength and support to the plant. Xylem parenchyma is a type of living cell that provides metabolic support to the xylem tissue. Xylem fibers, on the other hand, are elongated cells that provide additional support to the plant.

Option 2 is incorrect. Flexibility in plants is primarily due to collenchyma, a type of ground tissue that provides mechanical support to growing plant parts.

Option 3 is incorrect. Parenchyma cells have intercellular spaces between them, allowing for the exchange of gases and movement of substances within the plant.

Option 4 is incorrect. Sieve plates, sieve tubes, and companion cells are components of phloem, another complex tissue in plants that is responsible for transporting food and sugars from the leaves to
