Meristem or meristematic tissues are tissues capable of cell division which are found in all the regions of the plants where growth takes place such as in apex, near internodes and also at the sides (in the lateral position of the plant body).

Therefore, their roles include to aid the primary and secondary growth of the plant body.

Parenchyma :)

Sclereids or stone cells are the dead cells having extremely thick wall which are spherical or oval shaped. They are generally found in hard parts of plant body.

Cambium is alayer of actively dividing cells found between the xylem and phloem tissues that is

responsible for the secondary growth of stems and roots.

Annual rings are the rings arranged in concentric forms in the bark of the tree, their numebr represmts the age of the tree whereas their thickness depends upon the season that the tree has lived through.

Cortex, tissue of unspecialized cells, is located between the epidermis and the vascular tissue in the plants . It helps in the transportation of water and minerals to the center or core of the root through the process of diffusion.

Cuticle is the outermost waxy/hydrophobic layer made up of cutin; it's main function is to prevent the loss of water in form of water vapor through the epidermis. It also helps in reduction of transpiration in the xerophytic plants to prevent water loss and provides protection against desiccation.
