In the given columns, column I contain structures of female reproductive system and column II contain its feature. Select the correct match.
Column-IColumn-II
A. Lateral meristem(i) Fascicular vascular cambium, interfascicular cambium and cork cambium.
B. Apical meristem(ii) Produces dermal tissue, ground tissues and vascular tissue.
C. Bast fibres(iii) Generally absent in primary phloem but found in secondary phloem.
D. Sap wood(iv) Involved in the conduction of water and minerals from the root to leaf.

A. A - (i), B - (ii), C - (iii), D - (iv)

B. A - (iii), B - (i), C - (ii), D - (iv)

C. A - (i), B - (iv), C - (iii), D - (ii)

D. A - (ii), B - (iv), C - (iii), D - (i)

Correct Answer :

A. A - (i), B - (ii), C - (iii), D - (iv)


A: Lateral meristem is a meristem that is arranged parallel to the sides of an organ and that is responsible for increase in diameter of the organ. Fascicular vascular cambium, interfascicular cambium and cork cambium are the examples of lateral meristem.
B: Apical meristem is a completely undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to begin growth of new cells in young seedlings at the tips of roots and shoots (forming buds, among other things). During the formation of the primary plant body, specific region of apical meristem produces dermal tissue, ground tissue and vascular cambium.
C: Bast fibres or phloem fibres are made up of sclerenchymatous cells. These are generally absent in primary phloem but found in secondary phloem.
D: Sap wood is the peripheral region of the secondary xylem. It is involved in the conduction of water and minerals from root to leaf.
