Phylloclades are aerial modified stem, in which stem becomes thick, fleshy succulent, green and perform the function of photosynthesis. The leaves are reduced to spines in this.

Phylloclades:
Phylloclades are flat, green structures that have evolved from stems and function as leaves. These modified stems are found in certain plant species and serve the purpose of photosynthesis, just like regular leaves.
Characteristics of Phylloclades:
- Phylloclades are flat and leaf-like in appearance.
- They are green in color due to the presence of chlorophyll for photosynthesis.
- These modified stems lack typical leaf structures like a petiole or blade.
Function of Phylloclades:
- Phylloclades perform the essential function of photosynthesis, utilizing sunlight to produce energy for the plant.
- They help in the exchange of gases, such as carbon dioxide and oxygen, with the environment.
- Phylloclades also play a role in transpiration, the process of water loss through plant tissues.
Examples of Plants with Phylloclades:
- Some cacti species have phylloclades, which help them survive in arid environments by reducing water loss through transpiration.
- The genus Ruscus has species with phylloclades, enabling them to thrive in shaded areas where regular leaves might not receive enough sunlight.
In conclusion, phylloclades are specialized structures derived from modified stems, providing plants with the ability to photosynthesize and adapt to specific environmental conditions.
