A plant's cell wall is made of cellulose fibers. What is the purpose of a plant's cell wall?
Answers
in short- support the shape of plant
in long-Plants do not have bones like some animals do, so they will topple over without bones and a backbone. This is where the role of the cell wall comes in. It is a thick wall that helps to support the plant's shape and gives it the ability to stand without toppling over.
Another function is to act like a semi-permeable membrane. It allows water to get into the plant for use. Also, it allows the plant to have turgor pressure. This allows the plant to become become turgid when it takes in water, causing the cell wall to push externally against the plant, as well as letting it become stable.
plz mark it brainliest plzzzzzzzz
and follow me ..
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. ... The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses and pectin. Often, other polymers such as lignin, suberin or cutin are anchored to or embedded in plant cell walls.
Hope it help you...
