Thymus gland is the lymphatic tissue that commonly shrinks with age. It is responsible for producing T-cells important for immune function, and its size diminishes as we grow older.
The protective outer layers of a plant are composed of dermal tissue, which includes the epidermis and periderm. The epidermis is the outermost layer of cells that covers young plant parts, while the periderm replaces the epidermis in older, woody plant parts. Dermal tissue provides a protective barrier against physical damage, pests, and pathogens.
It sure does. In a tree trunk there is a thin layer of living tissue under the bark that grows out. The older parts die as it grows and become either the bark or the wood. So, wood is dead tissue, and therefore made of cells.
Cells of the pith of a stem generally have thick cell wall and large vacuoles. Likewise, cells of the cortex in the older parts have thick cell wall and large vacuoles.
Phloem cells are found in tree bark. These cells are responsible for transporting sugars and other organic compounds throughout the plant.
It means that your tissue is dying and your getting older.

In young dicot and monocot stems do not increase in thickness. Xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vascular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem.
No, as you get older your breast tissue becomes tender and the skin isn't as elastic as before and then gravity starts taking its place.
When you are growing, your cells go through processes or mitosis and myosis, which allows cell division to occur. One of the purposes of cell division is growth. All four tissue types are composed of cells which undergo myosis and mitosis and grow. Ergo as you grow, and get older, your tissue grow and get older as well.
increase in the adipose tissue
Depends on what ages you are talking about. Typically younger muscles are stronger than old ones.

In older woody plants, the epidermis of the stem is replaced by periderm, which includes tissues such as cork cambium, cork cells, and phelloderm. Periderm helps protect the stem and replaces the functions of the epidermis as the plant matures and its stems thicken.
