Hint: These are the plant tissues that occupy the space between two vascular bundles, that undergo secondary growth to help in the formation of the cambium ring.
Complete answer:
In the very beginning, the fascicular cambium is a primary meristem, later it gets transformed into a secondary meristem, during the secondary growth. Since this cambium lies between two vascular bundles it is called interfascicular cambium.
Additional Information: -During secondary growth, cells of medullary rays, that is cells between two vascular bundles become meristematic and form the new interfascicular cambium. Therefore interfascicular cambium is also called secondary meristem.
-They increase the thickness of the plant body and produce secondary tissue.
-They are mainly present between the primary xylem and primary phloem.
-They actively divide the cells producing xylem cells towards the inner side and the phloem cells towards the outer side and hence it increases the thickness of the plant.
So, the correct answer is, ‘secondary meristematic tissue’.
Note: -The intrafascicular and interfascicular cambium thus joined together to form a ring which separates the primary xylem and primary phloem, this ring is known as the cambium ring.
-The secondary xylem is produced inside of the ring, whereas the secondary phloem is produced outside of the ring in this way they push the primary xylem and phloem apart.
-There are two types of cells are consisted of vascular cambium:
(a) Fusiform initials: they are tall and axially oriented.
(b) Ray initials: they are smaller and round to angular in shape.
