(a), (c), (d) and (e) only

Answer 2

In the spring season, cambium is very active. The wood formed during this season is called spring wood or early wood.
- In spring season, cambium produces a large number of xylary elements having vessels with wider cavities and not narrow cavities.
-The spring wood is lighter in colour.
-The two kinds of woods (spring and autumnwood) appear as alternate concentric rings that constitute an annual ring. Annual rings seen in a cut stem give an estimate of the age of the tree.
-Springwood has a lower density.
