The transverse section of a plant material shows the following anatomical features:
(a) the vascular bundles are conjoint, scattered and surrounded by a sclerenchymatous bundle sheaths.
(b) phloem parenchyma is absent. What will you identify it as?
The scattered vascular bundles surrounded by sclerenchymatous bundle sheaths and the absence of the phloem parenchyma is unqiue to the monocot stem. Thus, the specimen is of a monocot stem.
Explain the process of secondary growth in the stems of woody angiosperms with the help of schematic diagrams. What is its significance?
Cut a transverse section of young stem of a plant from your school garden and observe it under the microscope. How would you ascertain whether it is a monocot stem or a dicot stem? Give reasons.
Draw illustrations to bring out anatomical difference between:
(a) Monocot root and dicot root
(b) Monocot stem and dicot stem
State the location and function of different types of meristems.
