A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary ...

Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure.

Water-filled vacuoles provide the inner pressure plant cells need for structural support. However, damage to the plant’s cell ...

UP to the present time, no X-ray investigations have been carried out on the molecular structure of chitin as present in plant cell-walls. The cell-walls of the sporangiophores of the fungus ...

Plant cells have a rigid cell structure. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus, and chloroplasts. Plants feel firm because of their cellular walls.
