1. Introduction

If you consider an atom or a molecule, it operates on a particular set of laws. These atoms and molecules organised together to form complex biological structures called organelles. These organelles organised together to form cells, and they combined to form tissues. Thus, tissues group together to form organs, organs make up organ systems, and organ systems combine to form organisms.

 

 

It is already mentioned that atoms are organised to follow a set of rules. Similarly, organelles, cells, tissues and organs are well organised at their levels. So we can say, plants also exhibit varying degrees of an organisation as they are also made up of tissues and organs.

 

The organisation of life is the classification of organisms into levels based on their size, shape, and complexity of their cells and tissues.

 

Vascular tissue (xylem and phloem) delivers water, minerals, and sugars to different plant sections, while dermal tissue covers and protects the plant. Photosynthesis takes place in ground tissue, which also serves as a supporting matrix for vascular tissue and aids in the storage of water and glucose.

 

 

So, multicellular organisms have a division of labour among cells to perform their various functions. Cells specialised in one function are of no use if they are scattered in different system regions. So they are grouped at a particular region of the body to do a specific function. These groups of cells are called tissues.

For example, in plants, the root, stem and leaves are organs; All the organs are made up of tissues such as,
