Question

Which part in plants secrete cellulose, pectin, lignin, Subeirn and cuitin???

Answer 1

Cellulose from major land and forest plants and cotton is assembled from glucose, which is produced in the living plant cell from photosynthesis.

Pectin is a major component of the middle lamella, where it helps to bind cells together, but is also found in primary cell walls. Pectin is deposited by exocytosis into the cell wall via vesicles produced in the golgi.

Lignin is a constituent of the cell walls of almost all dry land plant cell walls. It is the second most abundant natural polymer in the world, surpassed only by cellulose. Of the polymers found in plant cell walls, lignin is the only one that is not composed of carbohydrate (sugar) monomers.

Suberin is found in the phellem layer of the periderm (or cork). This is outermost layer of the bark. The cells in this layer are dead and abundant insuberin, preventing water loss from the tissues below. Suberin can also befound in various other plant structures.
