a. In roots, xylem and phloem in a vascular bundle are arranged in an alternate manner along the different radii.
b. Conjoint closed vascular bundles do not possess cambium.
c. In open vascular bundles, cambium is present in between xylem and phloem.
d. The vascular bundles of dicotyledonous stem possess endarch protoxylem.
e. In monocotyledonous root, usually there are more than six xylem bundles present.
Choose the correct answer from the options given below:
1. (a), (c), (d) and (e) only 2. (a), (b) and (d) only

The presence of protoxylem lacuna is considered a characteristic anatomical feature of:
1. Dicot stem, due to early disintegration of protoxylem elements
2. Monocot stem, resulting from the breakdown of protoxylem during development
3. Dicot root, due to radial arrangement of vascular tissues
4. Monocot root, due to presence of large pith
