In plants, different types of permanent tissues are found: 1. Simple Permanent Tissues: These are composed of similar cells and so are homogeneous in [...]
The following points highlight the three methods to make specific study of plant tissues. The methods are: 1. Preparation of Surfaces for Whole Mounts 2. Section Cutting 3. Maceration Method. Method # 1. Preparation of Surfaces for Whole Mounts: For the preparation of surfaces of different plant organs such as leaves and stems various techniques are followed. These preparations actually [...]
In this article we will discuss about the permanent tissue in plants:- 1. Simple Tissue 2. Complex Tissue. Permanent tissues are simple or complex, according to the nature of component cells. A simple permanent tissue is composed of only one type of cells and is thus homogeneous; whereas the complex permanent tissue is heterogeneous, consisting of more than one type [...]
