Answer 1

The answer is: (d) Phellogen.

Answer 2

The Correct option is A

Fusiform initials cells

Explanation:-

Vascular tissues are organized into discrete strands called vascular bundles, each containing xylem, and phloem. In stems, the vascular tissue is organized into several discrete vascular bundles. In roots, the vascular tissue is organized within a central vascular cylinder. The fusiform and ray initials of the cambium are divided into the surface tangent, also called the anticline of the stem, with the long axes of the fusiform and the ray initials parallel to the long axis of the plant organ. The cambium forms the xylem mother cells inside and the phloem mother cells outside. These cells in turn divide tangentially, producing new cells that join the xylem and phloem.
