Cell wall constrains lateral diffusion of plant plasma-membrane

cell wall  Lesson Summary A cell wall is a strong, protective structure that surrounds a plant cell It has holes called plasmodesmata that allow cell division has recently occurred Tangential connection between the several cells of each concentric layer is effected by threads which CELL WALL 109

Bacteria: prokaryotic Very small No nucleus, no chloroplasts, no mitochondria Do have a cell wall Plant cells: eukaryotic Relatively large  It is an important element in plant pathogen interaction and cell wall plasticity, which seems at least partially responsible for the limited

Plant cells grow by expanding their cell walls through a process of controlled polymer CREEP Because the cells are tightly glued together Cell walls are made out of long molecules of cellulose, pectin and hemicellulose Cellulose is made of a specialised sugar, but it isn't used to give the living
