While doing anatomy practical, students observe ten following characters:
(i) Undifferentiated ground tissue.
(ii) Numerous vascular bundles and are scattered.
(iii) Sclerenchymatous hypodermis.
(iv) Presence of bundle sheath.
Identify the material. Write any one example of a plant having such characters.

Differentiate the following characters of dicot stem and monocot stem. Differentiated cortex, Protoxylem lacuna present ,open bundle, bundle Sheath, starch sheath, sclerenchymatous hypodermis, scattered bundles,V.Bs. arranged in ring, closed bundle, phloem parenchyma absent , presence of pith, collenchymatous hypodermis.

In the anatomy lab. Eugin observed the following features in the T.S of a plant part. a) Radial and polyarch xylem bundles b) Parenchymatous (homogenous) cortex c) Large pith d) Epidermis with unicellular hairs e) Pericycle f) Endodermis with casparian strips. i) Identify the plant part. ii) Re-arrange the given regions from the periph-ery to the center in their correct sequence. iii) Give an account of casparian strips.
