In this article, we propose to discuss about the mechanical tissues of plant cell and their distribution. Some tissues are specially meant for providing mechanical strength or support to the plant members which are frequently subjected to various kinds of strains and stresses. The problem is not so acute in case of small herbaceous land plants and plants adapted to [...]
In this article, we will discuss about the complex tissues of plant cell. Xylem and phloem are the two complex tissues which are discussed hereunder. The complex tissues are heterogeneous in nature, being composed of different types of cell elements. The latter remain contiguous and form a structural part of the plant, adapted to carry on a specialised function. Xylem [...]
The following points highlight the three types of simple permanent tissue. They are: (1) Parenchyma (2) Collenchyma and (3) sclerenchyma. Type # 1. Parenchyma: Parenchyma (Fig. 534) is the most common simple tissue of the plants with relatively little specialisation. It is composed of cells which are usually isodiametric in shape with intercellular spaces. The cells have active protoplast. This [...]
