PeridermIt replaces the epidermis and cortex in stems and roorts with continual secondary
growth; these new layers (secondary phloem and periderm) are known as:

Annual rings are made of secondary xylem, which make up the wood of the stem surrounding the pith. Each annual ring has several rows of spring wood, thin-walled, large-diameter cells that grew in the spring, and, outside of these, a few rows of summer wood, thick-walled, smaller-diameter
cells that grew in the summer when water was less abundant.

Does this make sense?Spring = more available water = larger cells
Summer = less available water = smaller cellsThus, you can distinguish spring wood and summer wood by thicker and thinner rings,
respectively.
