Lateral meristems are meristematic tissues that are responsible for the growth in diameter of the plant. They occur in the mature regions of the root and shoot of many plants and contribute to secondary growth. There are two main types of lateral meristems:
1. Cork cambium: Cork cambium is a type of lateral meristem that occurs in the outer bark of woody stems and roots. It is responsible for the production of cork cells, which form the protective outer covering of the plant. Cork cambium produces cells both toward the inside (phelloderm) and outside (cork) of the stem or root, resulting in the thickening of the plant.
2. Fascicular vascular cambium: Fascicular vascular cambium is another type of lateral meristem that occurs within the vascular bundles of the stem. It is responsible for the production of secondary xylem (wood) towards the inside and secondary phloem towards the outside of the stem. This helps in the growth of the stem in diameter.
Based on the given options, the examples of lateral meristems are:
a. Cork cambium: Cork cambium is a lateral meristem that occurs in the outer bark of woody stems and roots. It contributes to the secondary growth of the plant by producing cork cells.
c. Fascicular vascular cambium: Fascicular vascular cambium is a lateral meristem that occurs within the vascular bundles of the stem. It is responsible for the production of secondary xylem and secondary phloem, leading to the growth in diameter of the stem.
Therefore, the correct answer is option 'A' - only a (cork cambium) and c (fascicular vascular cambium).
