Primary growth in plants refers to the growth that occurs in the length of the plant, such as the elongation of stems and roots. Secondary growth, on the other hand, refers to the growth that occurs in the width of the plant, such as the thickening of stems and roots.
The contract between primary and secondary growth in plants is that they work together to support the overall growth and development of the plant. Primary growth provides the initial structure and foundation for the plant, while secondary growth helps to strengthen and support the plant as it continues to grow.
Primary growth is responsible for the formation of the primary tissues in plants, such as the epidermis, cortex, and vascular tissues. Secondary growth, on the other hand, is responsible for the formation of secondary tissues, such as the cork cambium, vascular cambium, and secondary xylem and phloem.
Overall, primary and secondary growth work together to ensure that the plant is able to grow and thrive in its environment. They complement each other and play important roles in the overall growth and development of the plant.

Primary Growth
- Occurs in the primary meristems of roots and shoots (apical meristems). - Results in the formation of primary tissues (epidermis, cortex, vascular tissues). - Indeterminate growth, meaning it continues throughout the plant's life. - Typically responsible for the length of the plant.
Secondary Growth
- Occurs in the secondary meristems of stems and roots (lateral meristems). - Results in the formation of secondary tissues (wood, bark). - Results in the increase in diameter or girth of the plant. - Found in woody plants and some herbaceous plants.
Contract between Primary and Secondary Growth
- Primary growth occurs first and establishes the basic framework of the plant. - Secondary growth subsequently occurs in response to environmental factors and genetic signals. - Primary growth is essential for establishing the plant's height and overall shape. - Secondary growth provides support, protection, and water and nutrient transport. - The balance between primary and secondary growth determines the plant's ultimate size and form.
Specific Differences
| Feature | Primary Growth | Secondary Growth | |---|---|---| | Location | Apical meristems | Lateral meristems | | Tissues formed | Primary tissues | Secondary tissues | | Growth pattern | Indeterminate | Determinate | | Function | Establishes plant framework | Provides support, protection, and transport | | Occurrence | All plants | Woody plants and some herbaceous plants |
