Definitions / Explanation :
$(i)$ Conjoint vascular bundles
$(ii)$ Secondary growth
$(i)$ The vascular bundle in which xylem tissue and phloem tissue are arranged together, such a vascular bundle is called conjoint vascular bundle.
$(ii)$ In most of the dicot plants, after completion of primary growth due to formation of secondary tissue, the increase in girth is called secondary growth.
Which combination of tissues acts together to provide the support to the hypocotyl of a seedling
What part of the plant would show the following :
$(a)$ Radial vascular bundle
$(b)$ Polyarch xylem
$(c)$ Well developed pith
The vertical section of a dorsoventral leaf through the lamina shows three main parts namely, epidermis, ...$A$... and vascular system. The epidermis, which covers the upper surface is ...$B$... and lower surface is covered by ...$C$... of the leaf.
Choose the correct combination of $A , B$ and $C$
Draw illustrations to bring out anatomical difference between
$(a)$ Monocot root and dicot root
$(b)$ Monocot stem and dicot stem
Read the different components from $(i)$ to $(iv)$ in the list given below and tell the correct order of the components with reference to their arrangement from outer side to inner side in a woody dicot stem.
$(i)$ Secondary cortex $(ii)$ Wood $(iii)$ Secondary phloem $(iv)$ Phellem The correct order is
