What constitutes the cambial ring?
$\Rightarrow$ Interfascicular cambium : Interfascicular cambium and Intrafascicular cambium collectively form cambial ring. It is formed due to meristematic activity of them.
$\Rightarrow$ The cambium which is found between xylem and phloem, is called Intrafascicular cambium and new cambium formed between two vascular bundle is called Interfascicular cambium. Cambium ring is foamed by connecting two type of cambiums.
Lenticels are formed in bark, which are
The bark of tree comprises
As a tree grows older, which increases rapidly in thickness
Cork cambium forms tissues that form the cork. Do you agree with this statement? Explain.
$A$. Heart wood is durable, dark and central in position.
$B$. Tyloses are balloon like structures of xylem parenchyma in vessel lumen.
$C$. Late wood is formed during spring season.
