What is a lignin in the plants?
lignin hardened vascular tissues to transport water and nutrients
What does a vascular plant need to have to be a vascular plant?
Vascular plants have lignified tissues that are used to get water, minerals, and other products through the plant. Lignin is a chemical compound that is found in the cell walls of plants.
Is wheat a vascular plant?
Yes since it contains lignin
What are basic structural differences between bryophytes and vascular plants?
Bryophytes are land plants that are non-vascular plants. Most do not have special structures for the transport of water. If they do contain specialized structure for tranportation of water, they do not contain lignin, so they are not considered true vascular plants. They are mosses, hornworts, and liverworts. Vascular plants contain lignified tissues (xylem) for transporting water and spcialized non-lignified tissue (phloem) to conduct products of photosynthesis. They iclude clubmosses, horsetails, ferns, and gymnosperms (including conifers), and angiosperms (flowering plants).
What tissue is responsible for forming secondary xylem and phloem in terrestrial perennial plants?
Xylem is part of the vascular tissue of plants, and the xylem and phloem together are grouped together as the stele (latin for 'pillar'). Xylem tissue is encased in lignin, the substance that creates the strength of wood, causing the protoplasm (living part of the cell) to die, and therefore be dead tissue; phloem is living tissue.

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.
When did seedless vascular plants evolve?
The first seedless vascular plants evolved over 439 million years ago during the Silurian period. These early vascular plants developed the ability to synthesize lignin which gave them support.

Which structure is found in a angiosperms but not gymnosperms?
Embyrosac is found in Angiosperms but not in gymnosperms.
Difference between vascular and nonvascular plants?
Nonvascular plants lack lignin-impregnated conducting cells. They also lack an extensive transport system.

What are the only organisms that can be decomposed by fungi?
lignin
If phyloroglucin contains lignin?
One of the things that phyloroglucin contains is lignin.
What is the source of lignin in soil?
The source of lignin in the soil is dead plants.
