What else can I help you with?
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.
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 is The hardening substance sometimes contained in cell walls of sclerenchyma cells?
The hardening substance found in the cell walls of sclerenchyma cells is primarily lignin. Lignin provides structural support and rigidity, allowing these cells to withstand various stresses and contribute to the overall strength of plant tissues. Sclerenchyma cells are often dead at maturity and play a crucial role in supporting the plant, particularly in stems, leaves, and seeds.
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
What cells are dead have thick walls and support the plant walls?
Dead cells with thick walls that support plant walls are called sclerenchyma cells. These cells are highly specialized for mechanical support and are found in regions of the plant that require rigidity and strength, such as the stems and vascular tissues.
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.

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.
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
What is the difference between parenchyma and sclerenchyma?
• Sclerenchyma tissue has cells that have very thick lignified cell walls and are dead at maturity. • The primary functions of sclerenchyma are support and protection. • Some sclerenchyma cells are elongated, while other types are cubical or highly branched. • Elongated sclerenchyma cells are called fibres and provide strength and support to plant parts. Plants fibres have been used extensively by people to make twine, rope and cloth. •Collenchyma tissues are mainly found under the epidermis in stems in the large veins of leaves. • The cells are composed of living, elongated cells running parallel to the length of organs that it is found in (up the side of the stem) • Collenchyma cells have thick cellulose cell walls which are thickened at the corners. • Intercellular air spaces are absent or very small. • The cells contain living protoplasm (cytoplasm and nucleus) and they sometimes contain chloroplasts. •Cells in parenchyma tissue are thin walled and are often block-shaped. •Parenchyma cells remain alive at maturity and are abundant in roots, stems, leaves and fruit. •The primary functions of parenchyma tissue are photosynthesis in leaves and storage of food as starch granules. •You would expect such tissues to have many chloroplasts and/or amyloplasts
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.
What cells are dead have thick walls and support the plant walls?
Dead cells with thick walls that support plant walls are called sclerenchyma cells. These cells are highly specialized for mechanical support and are found in regions of the plant that require rigidity and strength, such as the stems and vascular tissues.
What is a sclerenchyma cell?
Sclerenchyma cells are the dead cells and they are devoid of protoplasm.The walls of Sclerenchyma are greatly thickened with deposition of lignin. Such cells are called lignified.Due to excessive thickening of the walls of sclerenchyma cell, its cell cavity or lumen is nearly absent.
Consumers that feed on tissues of dead animals?
consumers that deed on the tissues of dead animals
The woody cells of a tree are formed from dead connective tissues true or false?
False. The woody cells of a tree are primarily formed from living cells called cambium that produce new layers of xylem and phloem, which then become part of the tree's structure as they mature and lignify. Wood cells themselves are actually dead at maturity and provide structural support to the tree.
The primary function of very thick walled cells in the stem of a plant is?
The primary function of very thick-walled cells in the stem of a plant is to provide structural support and rigidity, especially in larger, woody plants. These cells, known as sclerenchyma cells, are dead at maturity and have extremely thick walls made of lignin, which makes them strong and durable.
