|
cell wall
|
The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins. |

|
carbohydrate metabolic process
|
The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule. |
|
GO:0004553
|
hydrolase activity, hydrolyzing O-glycosyl compounds
|
Catalysis of the hydrolysis of any O-glycosyl bond. |
|
GO:0006073
|
cellular glucan metabolic process
|
The chemical reactions and pathways involving glucans, polysaccharides consisting only of glucose residues. |
|
GO:0016762
|
xyloglucan:xyloglucosyl transferase activity
|
Catalysis of the cleavage of a beta-(1->4) bond in the backbone of a xyloglucan and transfers the xyloglucanyl segment on to O-4 of the non-reducing terminal glucose residue of an acceptor, which can be a xyloglucan or an oligosaccharide of xyloglucan. |

GO:0048046
|
apoplast
|
The cell membranes and intracellular regions in a plant are connected through plasmodesmata, and plants may be described as having two major compartments: the living symplast and the non-living apoplast. The apoplast is external to the plasma membrane and includes cell walls, intercellular spaces and the lumen of dead structures such as xylem vessels. Water and solutes pass freely through it. |
