Question

Accepted Answer

It is one of the many layers of bark, between the cork and primary phloem. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. ... The function of cork cambium is to produce the cork, a tough protective material.

Answer

Lateral meristems occur laterally in the axis, parallel to the sides of stems and roots . The cambium of vascular bundles (fascicular, interfascicular and extrastelar cambium) and the cork cambium (phellogen) belongs to this category.

Answer

Cork cambium is lateral in nature means that it would help the plant to grow in horizontal (lateral) direction.so Cork cambium is an example of lateral meristem.

Answer

Lateral Meristem:
The cork cambium is an example of a lateral meristem. Lateral meristems are responsible for the increase in girth or thickness of a plant. These meristems are found in the cambium layer of the plant.

Cork Cambium:
The cork cambium, also known as phellogen, is a type of lateral meristem that produces cork cells. It is found in the outermost layer of the stem, roots, and branches of woody plants. The cork cambium is responsible for the formation of the protective layer called cork.

Function:
The main function of the cork cambium is to produce cork cells on its outer side and phelloderm cells on its inner side. The cork cells are dead at maturity and have suberin in their cell walls, which makes them impermeable to water and gases. This layer of cork cells provides protection to the underlying tissues from mechanical damage, desiccation, and pathogens.

Formation of Cork Cambium:
The cork cambium is formed from the secondary meristem called the vascular cambium. The vascular cambium is a type of lateral meristem responsible for the production of secondary xylem (wood) and secondary phloem. As the plant grows older, the vascular cambium differentiates into two layers - the outer cork cambium and the inner secondary phloem.

Periderm Formation:
The cork cambium produces cork cells towards the outside and phelloderm cells towards the inside. The cork cells form the outermost protective layer called the periderm. The phelloderm cells, on the other hand, contribute to the cortex of the plant. As the cork cells are produced, the older layers of cork are pushed outward, resulting in the formation of the bark.

Conclusion:
In conclusion, the cork cambium is an example of a lateral meristem. It is responsible for the production of cork cells, which form the outer protective layer of the plant. The cork cambium plays a crucial role in protecting the plant from external factors and is an essential part of the plant's structure and function.
