A typical monocotyledonous root is characterised byA. usually more than six xylem bundlesB. Large and well develped pithC. no secondary growthD. all of these |
|
Answer» Correct Answer - D There is no distinction between a young and an old root of monocotyledonous plant. This is due to the absence of secondary growth in the monocot roots. The centre of moncot root is occupied by the pith. It consists of parenchymatous cells which may be rounded or angular . intercellular spaces are present amongst the pith cells. the pith cells store food. Xylem and phloem bundles are numerous and are 8 or more in number. |
