Question

Select the tissue/elements from the following, which
does not provide mechanical support to the plant parts.

1). Parenchyma
2). Collenchyma
3). Sclerenchyma
4). Xylem tracheids​

Answer 1

Answer:

the Answer is xylem trachieds

Answer 2

Answer:

Parenchyma– These tissues are found in the soft parts of a plant such as the roots, stems, leaves, and flowers. The cells of this tissue are loosely packed and contain large intercellular spaces between them. Each cell has a vacuole at the center. The functions of parenchyma tissues are storage, photosynthesis, and to help the plant float on water.

Collenchyma- Are similar to parenchyma cells with thicker cell walls. They are meant to provide mechanical support to the plant structure in parts such as petiole of the leaf.

Sclerenchyma- The cells of this tissue are dead. They are rigid, contain thick and lignified secondary walls. Their main function is to provide strength and support to parts of the plant.

Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. ... The water‐conducting xylem cells provide an internal hydrophobic surface facilitating water transport as well as mechanical strength.
