Question

Tracheids do not collapse under extreme tension due to the presence of (1)Strong,elastic lignocellulosic secondary cell wall (2)Thick,cellulosic primary cell wall (3)Thin,elastic,cellulosic primary cell wall (4)Thick,hard suberised secondary cell wall

Answer 1

Answer:

1 is the correct option and answer

tthick and elastic secondary cell wall helps in it

Answer 2

Answer:

The correct option is (1) Strong, elastic lignocellulosic secondary cell wall.

Explanation:

Tracheids

• Tracheids are elongated and tubular cells that provide structural support in plants.
• This secondary cell wall, composed mainly of lignin, cellulose, and hemicelluloses, makes tracheids resistant to collapse under extreme tension.
• The presence of lignin, in particular, confers the mechanical strength and rigidity needed to maintain the shape of tracheids under stress.
• This lignocellulosic secondary cell wall also makes tracheids impermeable to water, which is essential for maintaining turgor pressure and preventing the cells from collapsing.
• Tracheids differ from other types of plant cells, such as xylem vessels and parenchyma cells, in their shape, size, and function.
• Unlike xylem vessels, tracheids do not have perforations in their walls and rely on transpiration pressure to transport water.
