What are the two tissues that are thickened by lignin?
The two types of tissues that are thickened by lignin are xylem and sclerenchyma. Xylem is responsible for water transport and provides structural support in plants, while sclerenchyma consists of supportive tissues that have thickened cell walls, often found in stems and seeds. The presence of lignin in these tissues enhances their rigidity and durability.
Which tissues Supports and strengthens a plant?
Mechanical tissues like sclerenchyma & collenchyma
Are there visible nuclei in the sclerenchyma tissue?
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
How does sclerenchyma structure relate to their function of support?
Sclerenchyma have long columns of cells, each cell is thick. The end walls of sclerenchyma are often perforated (contain holes). Xylem and phloem are often surrounded by layers of sclerenchyma
Why sclerenchyma does not has intercellular spaces?
Sclerenchyma cells have thick, rigid cell walls made of lignin, which provides structural support to the plant. These thick walls don't leave room for intercellular spaces, resulting in a dense and compact arrangement of cells. This lack of intercellular spaces contributes to the strength and rigidity provided by sclerenchyma tissues.

What includes parenchyma collenchyma and sclerenchyma?
These are types of plant tissues responsible for support and structure. Parenchyma tissue functions in photosynthesis and storage. Collenchyma tissue provides flexible support to growing plant parts. Sclerenchyma tissue offers rigid structural support through thickened cell walls.
Which plant cells function in providing support and are dead at maturity?
Sclerenchyma cells provide support in plants and are typically dead at maturity. These cells have thick, lignified cell walls that provide structural support to the plant's tissues.
Which tissues Supports and strengthens a plant?
Mechanical tissues like sclerenchyma & collenchyma
What is the long cells with unevenly thickened cell walls this type of cell wall allows the cells to grow?
The long cells with unevenly thickened cell walls are called sclerenchyma cells. The uneven thickening of cell walls provides strength and support to the plant, allowing it to grow tall and withstand mechanical stress. These cells are dead at maturity and provide structural support to plant tissues.
Are the kinds of fundamental tissues?
sclerenchyma, collenchyma, parenchyma
Which tissues are present in the hard covering ofthe seeds?
Sclerenchyma
Where is the location of sclerenchyma?
Sclerenchyma cells are located in the supportive tissues of plants, such as stems, roots, and seed coats. They have thick, lignified cell walls that provide rigidity and structural support to the plant.

The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.

3 simple tissues and their location in plants?
Parenchyma Sclerenchyma,Collenchyma. Present on permanent tissues where cessation of growth has occurred.
