Dear student,
Please find below the solution to the asked query
 
1.
Cambium
is a type meristematic tissue that helps in the secondary growth of stem and root of the plant. It includes: Vascular cambium present between phloem and xylem that produces secondary phloem and xylem and Cork cambium found as part of the periderm that replaces epidermis in stem and roots of plant.
Cambium is a secondary meristem and is formed from the primary permanent tissues. The primary permanent tissues like parenchyma tissues regain the meristematic activity and become secondary meristems i.e cambiums.‚Äč

2.
In spring season, cambium is very active and produces a large number of xylary elements with wider vessels. This wood is called spring wood or early wood. It is lighter and has lower density.

In winters, xylem is less active and forms fewer xylary elements with narrow vessels. This wood is called autumn wood or late wood. It is darker and has higher density.
