However, the primary cell wall, can be defined as composed of cellulose microfibrils aligned at all angles.

The primary cell wall, generally a thin, flexible and extensible layer formed while the cell is growing.

The major polysaccharides making up the primary cell wall of land plants are cellulose, hemicellulose, and pectin.

The cells develop an extensive secondary cell wall that is laid down on the inside of the primary cell wall.

It is placed between the two primary cell walls of two plant cells and made up of intracellular matrix.

Primary cell walls of graminoceios monocots contain very little pectin and the species have low boron requirements.

The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane.

Pectin is an important cell wall polysaccharide that allows primary cell wall extension and plant growth.

Pectin is a major component of the middle lamella, where it helps to bind cells together, but is also found in primary cell walls.

The secondary cell wall, a thick layer formed inside the primary cell wall after the cell is fully grown.

Primary wall formation is similar to that reported for other species of Pezizales.

The staining of the primary wall, however, is coarsely granular.

Parenchyma cells have thin primary walls and usually remain alive after they become mature.

The secondary cell wall has different ratios of constituents compared to the primary wall.

Primary wall formation is similar in all species examined, although very early development was observed only for H. macropus.

Simultaneously, the primary wall of the aeciospores broke down, exposing the verrucae.

Lignification always proceeds first in the middle lamella then out through the primary wall...

Eventually the warts push through the primary wall and darken which is likely caused by melanin.

Frequently, it is difficult to distinguish the middle lamella from the primary wall, especially in cells that develop thick secondary walls.

Ultrastructural studies show that the cyanophobic spore markings are part of the primary wall.

Unlike the primary wall, the microfibrils are aligned mostly in the same direction, and with each additional layer the orientation changes slightly.

This can be seen as dark patches on the primary wall as the fusion septum dissolves.
