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.

What is a lignin in the plants?
Lignin is a complex organic polymer found in the cell walls of plants. It provides structural support to the plant cells and helps transport water through the plant. Lignin is responsible for the rigidity and strength of plant tissues.
Do epidermal cells from petunia stain with phloroglucinol?
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.
Is Lignin found in root hairs?
Lignin is not typically found in root hairs. Lignin is a complex polymer that provides structural support to plant cell walls, but it is more commonly found in tissues such as stems, branches, and trunks where rigidity and strength are needed. Root hairs primarily play a role in nutrient uptake and anchoring the plant in the soil.
What is 'lignin'?
Lignin is a complex polysaccharide (therefore a carbohydrate). http://en.wikipedia.org/wiki/Image:Lignin_structure.svg There are no amino acids, nitrogenous bases, or fatty acids-- therefore lignin must be a carbohydrate and have sexy glycosidic linkages. Wikipedia says it so it must be true. ~Period 1 AP Bio (Fowler)
How are xylem tissues adapted for support?
Xylem tissues are adapted for support primarily through the presence of lignin, a complex polymer that provides structural strength and rigidity to the cell walls. The xylem vessels are elongated and have thickened walls, allowing them to withstand the negative pressure generated during water transport while also providing mechanical support to the plant. Additionally, the arrangement of xylem cells in a network helps distribute mechanical stress, enhancing the overall stability of the plant. These adaptations enable plants to grow taller and compete effectively for sunlight.

Is lignin found in ferns and bryphytes?
Lignin is primarily found in the cell walls of vascular plants, providing structural support. While ferns, which are vascular plants, do contain lignin, bryophytes (like mosses and liverworts) do not have lignin, as they lack vascular tissues. Instead, bryophytes rely on other structural compounds for support.
Do epidermal cells from petunia stain with phloroglucinol?
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.
What does the pattern of lignin deposition determine?
The pattern of lignin deposition determines the mechanical strength and water-conducting properties of plant tissues. It provides structural support to plant cells and helps in the transport of water and nutrients throughout the plant.
What is lignin where is it present?
Lignin is a complex organic polymer found in the cell walls of plants, providing structural support and rigidity. It is primarily present in the woody tissues of plants, such as trees and shrubs, as well as in other vascular plants like grasses.
Is Lignin found in root hairs?

Lignin is a complex polymer that provides structural support to plant cell walls, but it is more commonly found in tissues such as stems, branches, and trunks where rigidity and strength are needed.

What is the thickened mass of cells on the blastocyst from which the baby will develop is called the?
The thickened mass of cells on the blastocyst from which the baby will develop is called the inner cell mass (ICM). The ICM gives rise to the fetus and the tissues of the body.

What is the source of lignin in soil?
The source of lignin in the soil is dead plants.
If phyloroglucin contains lignin?
One of the things that phyloroglucin contains is lignin.
Why is it surprising to find lignin in aquatic plants?
Lignin is a biopolymer that gives support to vascular plants, and is thought to have evolved after aquatic plants took on land. many aquatic plants produce lignin or lignin-like polyphenols however. There is still debate on distinguishing terrestrial from aquatic plant lignin.
