Overview of the Chapter
Anatomy is a branch of science dealing with the internal structure of plants and animals. Thus, plant anatomy deals with the composition and arrangement of tissues within a plant. Tissues are aggregates of similar cells which perform certain functions together. The two types of tissues found in plants are meristematic and permanent. Meristems contribute to the plant's growth and the formation of new cells, while permanent tissues are for definite purposes: support the plant and transport water and nutrients. It is important to know this before one tries to understand how flower plants work, survive their environment, and thus thrive.

What is the Anatomy of Flowering Plants?
The anatomy of flowering plants refers to the study of the inner structures of flowering plants, such as tissues and cells. The two main tissue types are meristematic or growth tissue and permanent tissues, which are differentiated cells like parenchyma, xylem, and phloem. Key aspects include the anatomy of roots, stems, and leaves, which each consist of protective layers, storage cells, and vascular tissues for transport. Plant anatomy is a basic study area of plant physiology and adaptations, which helps to understand the functions and how plants interact with their surroundings.
Permanent Tissues
Complex and Simple tissue are two different forms of permanent tissues.
Complex Tissues
The phloem and xylem make up complex tissues.
The following elements make up phloem (main food conducting tissue):
Phloem fibres - they are unbranched and sclerenchymatous and are absent in primary phloem.
The perforated ends of sieve tubes. They are long, slender cells that are arranged end to end.
Living cells that store food are known as phloem parenchyma.
Elongated cells are known as companion cells. Gymnosperms lack them, whereas angiosperms have them in abundance.
Xylem
The xylem is made up of four different components.
The xylem parenchyma is made up of living cells that store lipids and carbohydrates.
Tracheid cells are lignified and hard-walled dead cells. They have blunt tips, which aid in water conduction in plants.
The lignified xylem fibres have pointed ends. This aids the transport of nutrients and water from the root to the leaf and provides mechanical support.
Vessels are tube-like structures that die when they reach adulthood. They support the facility mechanically and are involved in water transportation.
Phloem
Function: Transportation of organic nutrients mainly sugars from the leaves to other parts of the plant.
Constituents
- Sieve Elements: Facilitate nutrient transport with perforated end walls.
- Companion Cells: Assist the role of sieve cells and also in nutrient transport
- Phloem Parenchyma: Storage of nutrients and also assisting in transport
- Phloem Fibers: Provides mechanical support
Transport Mechanism: Pressure flow transport in the direction from source (leaves) to sink (roots/ fruits)
Living Tissue: Consists of living cells, it supports active transport.

Simple tissues
Simple Tissues are divided into three categories.
Collenchyma is made up of live thickened cells at the corner due to the deposition of pectin, hemicellulose, and cellulose.
The cells of the parenchyma are simple and unspecialized.
Cortex, Pith, Pericycle, and Epidermis are all places where they can be found. They play a role in food storage, photosynthesis, and other processes.
Sclerenchyma Long, tapering cells that have been lignified. These are dead cells that play a role in the mechanical function of the body.

Meristematic Tissue
- Meristematic tissue is defined as a collection of cells with the ability to divide.
- Meristems come in three varieties.
- The Intercalary Meristem can be seen on the leaf blades and node bases.
- The Apical Meristem can be found on the root and shoot apices.
- Plants can grow laterally with the help of the Lateral Meristem.
- Apical Meristems can be found in the plant's shoot, root, or tip.
- They are recognized as cells that are actively dividing.

Root Anatomy
Roots are important for the stability, nutrition, and water uptake of a plant. There are many different root systems, and each is specially adapted for specific environments and functions. Here are the main types:
| Feature | Dicot Roots | Monocot Roots |
|---|---|---|
| Taproot System | Prominent single taproot with lateral roots. | Fibrous root system with thin, spreading roots. |
| Vascular Tissue Arrangement | Star-like pattern; xylem in "X" shape, surrounded by phloem. | Circular arrangement; xylem and phloem in separate bundles. |
| Root Cap and Meristem | Well-defined root cap and apical meristem. | Present root cap and apical meristem. |
| Anchorage | Strong anchorage; deep soil penetration. | Provides stability, and prevents soil erosion. |
| Nutrient Absorption | Efficient nutrient and water absorption from deep soil. | Efficient in absorbing moisture and nutrients from upper soil layers. |
| Examples | Carrots, beets, dandelions, sunflowers. | Grasses, wheat, rice, lilies. |
Anatomy of Plant Stem
Three basic tissue systems make up the anatomy of a stem, and these are epidermal, ground, and vascular tissues. The outside layer offers protection as an epidermis, while the inner side is the supporting storage area known as the ground tissue, followed by the vascular tissues consisting of the xylem and phloem that carry water, nutrients, and sugars within the plant. Altogether, all these make the entire plant stem grow and function properly.
The table below shows the main difference between monocot and dicot stem:
| Feature | Monocot Stem | Dicot Stem |
|---|---|---|
| Vascular Bundle Arrangement | Scattered throughout the stem. | Arranged in a ring. |
| Type of Vascular Tissue | Typically has fewer vascular bundles. | More vascular bundles with a defined cambium layer. |
| Cortex and Pith | The cortex is not differentiated, and the pith is large. | Cortex and pith are well-defined. |
| Growth | Limited secondary growth, mostly herbaceous. | Exhibits significant secondary growth, often woody. |
| Node and Internode | Nodes and internodes are usually shorter. | Longer internodes; well-defined nodes. |
| Examples | Corn, wheat, bamboo, and palm trees. | Sunflower, oak, rose, and bean plants. |
Anatomy of Leaf
The anatomy of a leaf is made up of multiple layers, including the epidermis, which acts as the outer protective layer, and the mesophyll layer, where photosynthesis takes place, divided into two layers: palisade and spongy layers. The vascular tissue consists of xylem and phloem, which transport water and nutrients. The stomata are mainly located on the lower epidermis and allow carbon dioxide to enter and oxygen to leave for gas exchange, an important function in photosynthesis and respiration.
| Feature | Monocot Leaf | Dicot Leaf |
|---|---|---|
| Leaf Shape | Usually long and narrow with parallel veins. | Broad with a variety of shapes and net-like (reticulate) veins. |
| Venation | Parallel venation (veins run parallel to each other). | Reticulate venation (veins form a branching network). |
| Petiole | Often short or absent; leaf blades can be sheathed. | Well-defined petiole connecting leaf to stem. |
| Stipules | Usually absent. | Often present at the base of the petiole. |
| Photosynthesis | Efficient for capturing sunlight in narrow spaces. | A large surface area allows for effective photosynthesis. |
| Gas Exchange | Stomata are usually distributed evenly on both surfaces. | Stomata are mainly located on the lower surface to reduce water loss. |
| Examples | Grasses, lilies, and corn. | Maple, oak, and rose. |

Frequently Asked Questions (FAQs)
In simple terms, a plant's permanent tissues are those that contain non-dividing cells. In addition, the cells are altered to serve certain activities in the plants. Intercellular gaps can be seen in the spaces between the cells. Inside these cells, there are also large vacuoles.
Plant tissues are divided into two categories: meristematic tissues and permanent tissues.
They are made up of cells that are capable of dividing. They can be further divided into three categories: Intercalary meristem, Lateral meristem, Apical meristem
All parenchyma cells have one thing in common: they are mature and capable of cell division, which means they play a crucial role in wound healing and regeneration. Photosynthesis, storage, secretion, and transport are all important functions of these cells.
Nehemiah Grew is the father of plant anatomy.
The anatomy of flowering plants, or angiosperms, refers to their internal structures, which include various tissues and organs. Key components include:
- Tissues:
- Meristematic Tissue: Actively dividing cells responsible for growth, including apical, intercalary, and lateral meristems.
- Permanent Tissue: Differentiated cells that do not divide further, categorized into simple (one cell type) and complex (multiple cell types).
- Vascular System: Composed of xylem (water transport) and phloem (nutrient transport). Xylem includes tracheids and vessels, while phloem consists of sieve tubes and companion cells.
