Simple tissue consist of one same type of cells while complex tissue have different type of cells.

Simple tissue consist of  parenchyma, collenchymas and sclernchyma. While complex tissue consist of  xylem and phloem.

Simple tissue occur in all parts of plant and complex tissue only occur in vascular region.

Simple tissue have wide distribution and complex tissue have restricted distribution.Complex tissue carries out function of conduction or transportation.

Simple tissues perform wide range of functions.The function of simple tissue is storage of food, while the function of complex tissue is protection.

Complex tissue prevent water loss and they even help in gaseous exchange.

Difference between Simple Tissue and Complex Tissue
The main difference between simple tissue and complex tissue lies in their structure, function, and composition.

Simple Tissue:
- Simple tissues are composed of similar types of cells that perform a common function.
- They are made up of only one type of cells, such as parenchyma, collenchyma, and sclerenchyma.
- These tissues are responsible for functions like photosynthesis, storage, and support in plants.
- Simple tissues are found in all parts of the plant body, including leaves, stems, and roots.

Complex Tissue:
- Complex tissues are composed of more than one type of cells working together to perform a specific function.
- They are made up of different types of cells, such as xylem and phloem, which are involved in transporting water, nutrients, and organic compounds throughout the plant.
- These tissues are responsible for conducting water, minerals, and food materials in plants.
- Complex tissues are typically found in the vascular bundles of plants, such as in the stems and roots.
In conclusion, simple tissues are made up of one type of cells that perform a common function, while complex tissues are composed of different types of cells working together to carry out a specific function. Both types of tissues play crucial roles in the growth, development, and overall functioning of plants.
