Exp:B Meristem consist of cells in continuous state of cells division. It have a great potential for division. Meristems generally divided continuously and form a cluster of cells that further undergoes maturation to produce specialized cells. Meristematic tissues are responsible for plant growth these tissues constantly divide to produce new cells.

Vertically elongated cells in the lateral meristem producing axial system in the secondary xylem and phloem are known as I. Fusiform initials II. Combium cells III. Phellogen cells
1 Only I
2 I and II
3 II and III
4 I, II and III
Explanation:
Exp:A Vertically elongated cells in the lateral meristem producing axial system in the secondary xylem and phloem are known as 'fusiform initials'. They are elongated cells, which results in the production of cells that form the vertical system of secondary phloem and xylem, tracheary elements, sieve cells, fibres and the associated companion cells. Fusiform initials cell give rise to secondary xylem and phloem.

The secondary meristem initiates
1 Basal growth
2 Transverse growth
3 Radial growth
4 Vertical growth
Explanation:
Exp:C The secondary meristem initiates the 'radial growth'. Secondary meristem are responsible for the radial or secondary growth of plants. They also increases the thickness of plant body. Radial growth is a secondary growth which increases the girth or radius of a plant.

Quiescent centre is found in root apex and acts as
1 permanent source of active initiates
2 reservoir of resistant cells
3 reservoir of passive cells to form new root apex if root apex is damaged/killed
4 All of the above
Explanation:
Exp:D Quiescent centre is found in root apex and acts as permanent source of active initiates. It acts as a reservoir of cells which constitute a permanent sources of active initials. Cells of inactive region of quiescent centre become active when the previously active gets damaged.

Primary growth is caused by :
1 apical meristem
2 lateral meristem
3 dermatogen
4 plerome
Explanation:
Exp:A Primary growth is caused by apical meristem. This growth is initiated by the apical meristem and it helps the plant to grow upward. Apical meristem is present at the growing tips of roots and shoots and produce primay tissues.
Exp:B Meristem consist of cells in continuous state of cells division. It have a great potential for division. Meristems generally divided continuously and form a cluster of cells that further undergoes maturation to produce specialized cells. Meristematic tissues are responsible for plant growth these tissues constantly divide to produce new cells.
