Lignified cells are cells that contain lignin, which is used for structural support in plants.
To provide regidity to the plant
Lignified means made hard like wood as the result of the deposition of lignin in the cell walls I found this word in one of the other questions so I decided to search it up myself.
Xylem is the complex tissue of plants that helps in the transportation of water and nutrients in the plant. Phloem refers to the living tissue which helps in the transportation of food and organic materials in the plant.
Collenchyma's cell walls are very thick by pectic substances. They are shaped like hexagons. They have a large vacuole in the center. When the cells die they become sclerenchyma. Then the vacuole becomes an empty thing called a lumen & the cell wall becomes lignified. It's found in plant stems, leaves & flowers.
Dead , their walls become lignified. Lignin is waterproof and prevents osmosis occurring so the cell dies.
Bryophytes are small, low growing plants that are found in moist environments. Bryophytes do not have lignified tissue. Lignified tissue is hard like a tree bark.
Cellulose in living plant cells and Lignified cellulose in non-living plant cells (As in heartwood and outer bark)Phloem
To provide regidity to the plant
collenchyma helps in making food and sclerenchyma gives mechanical support to plant body Edited answer: Collenchyma cells are thick at the corners whereas sclerenchyma cells are lignified all around. Both serve as mechanical tissue.
Nope, only in xylem.
A complex polymer, the chief noncarbohydrate constituent of wood, that binds to cellulose fibers and hardens and strengthens the cell walls of plants
Plants that have lignified tissues for conducting water, minerals, and photosynthetic.

The wood largely consists of trachieds. these are lignified cells attached to each other by calcium pectate, a substance which works as a cementing material. Therefore due to elasticity of the trachieds, it is difficult to get powder of it by hammering.
Nonvascular plants such as liverworts and mosses don't have this kind of tissue. Without lignified vascular tissue, this liverwort cannot transport nutrients or water from its rhizoids to other cells that are more than a few millimeters away.
Pollen transported by wind, lignified xylem, and microscopic gametophytes
