Inner Bark
A
Growth layer in a tree root, trunk, or limb
B
Rings in a cross section of a tree root, trunk, or limb representing one year’s growth
C
Cell structures that transport water, minerals, and nutrients within plants from the roots to the leaves
D
phloem; transports food downward in a tree
Explanation: 

Detailed explanation-1: -The photosynthates from the source are usually translocated to the nearest sink through the phloem sieve tube elements. For example, the highest leaves will send sugars upward to the growing shoot tip, whereas lower leaves will direct sugars downward to the roots.

Detailed explanation-2: -B: The inner bark, or “phloem”, is pipeline through which food is passed to the rest of the tree. It lives for only a short time, then dies and turns to cork to become part of the protective outer bark.

Detailed explanation-3: -In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), particularly sucrose; a sugar, to all parts of the plant.
