They differ in structure from the fibrous celluloses and are probably not cell-wall building material.
Can you distinguish a nucleus and cell-wall in the blood-cells?
After the fertilization is completed the first happening is the formation of a cell-wall round the ovum.
These then become surrounded by a cell-wall and form the spores.
The framework material, as the name indicates, constitutes the cell-wall and other skeleton substances of the plant.
Cells may, or may not, be enclosed in an investing coat or "cell-wall."
The cell is frequently, but by no means always, bounded by a cell-wall of greater or less thickness.
The three cells at the opposite end are known as antipodal cells and become invested with a cell-wall.
Here the conjugating cells swim free in water; they have no cell-wall, and move actively by cilia.
In the latter case, it forms an inner cell to the cell-wall, and is called the primordial utricle.
cell wall n.
The rigid outermost cell layer found in plants and certain algae, bacteria, and fungi but characteristically absent from animal cells.
|cell wall |
The outermost layer of cells in plants, bacteria, fungi, and many algae that gives shape to the cell and protects it from infection. In plants, the cell wall is made up mostly of cellulose, determines tissue texture, and often is crucial to cell function. Compare cell membrane.
