Answer 2

Yes

Explanation

All the stems of plants and trees are green in colour when young. But why does the colour of the stem change to brown as they grow older?

The stem of all plants is green due to the presence of hypodermal chlorenchyma in its cortex. But when the stem axis, especially the dicot stem axis, ceases to elongate and undergoes secondary growth, its green colour disappears and becomes pale or dark Brown in colour.
