Detailed explanation-1: -Animals do not have meristematic tissues. Hence, the growth phase gets static after maturity in animals. However, cell division continues in our body to replace damaged and worn out cells in certain body parts.

Detailed explanation-2: -The cork cambium also is a secondary meristem, containing meristematic cells. The cork cambium forms a major portion of the bark of woody plants.

Detailed explanation-3: -In plants, these tissues are located where active growth takes place such as in the tips of stems, roots, leaves, etc. In woody plants, meristematic tissues are located in the vascular cambium.

Detailed explanation-4: -Answer: (b) Girth of the stem increases due to lateral meristematic tissues. They are found beneath the bark (called cork cambium) and in vascular bundles of dicot roots and stems (called vascular cambium) as thin layers.
