Plants play a major role in our life. Without plants, there would be no more life existing on planet earth. Plants provide many products for human use- air to breathe, food to eat, shelter, fabrics to cover our body, medicines, timbers and many products. There are around three lakh identified plant species and this list is still increasing.
The plants that we see today are the result of 470 million years of evolution. During this long timeframe, plants have evolved into an innumerable number of species, with each member having their own characteristic features. The last to evolve among these is the angiosperms or the Flowering Plants.
Anatomy of Flowering Plants Class 11 Notes explains the complete information related to the plant structure, functions and its importance to the plant’s internal structure.

Anatomy of Flowering Plants
Anatomy is the branch of biology concerned with the study of the internal structures or organ systems of an organism. The anatomy of flowering plants is the study of the structure of organisms and their parts.
Plant Anatomy is also called phytotomy. It is the study of the internal structure of a plant, including the tissues, root system, stem, leaves, flower, fruit and seeds.

What are Flowering Plants?
Angiosperms are also referred to as flowering plants. They are the only plants in the plant kingdom capable of producing flowers, fruits and seeds. Furthermore, flowering plants are the most diverse, with over 295,000 species discovered to date and represent the most advanced group of plants which have been of immense importance to humans. These plants are able to grow in a variety of habitats.
Also Read: Morphology of Flowering Plants
Flowering Plants primarily comprises two tissues, namely meristematic and permanent tissue.
Meristematic tissue is further composed of 3 types of tissues that serve very specific functions:
- Apical tissue
- Intercalary tissue
- Lateral tissue
Permanent tissues are classified into 2 types, namely:
- Simple tissue
- Complex tissue
