Identify the incorrect statement.

Easy

A

In the spring season, cambium is very active and produces many xylary elements having vessels with wider cavities.
B

The spring wood is darker in colour and has more density.
C

Spring wood and autumn wood appear as alternate concentric rings which are formed in a year, constitute an annual ring.
D

In autumn, the cambium is less active and forms fewer xylary elements that have narrow vessels.

Solution

The spring wood is lighter in colour and has a lower density whereas the autumn wood is darker and has a higher density.
The activity of cambium is under the control of many physiological and environmental factors. In temperate regions, the climatic conditions are not uniform through the year. This differential activity produces the light colured spring wood in the spring season and the dark coloured autumn wood in the autumn season.
