Water containing cavities in vascular bundles are found in:
1 Cycas
2 Pinus
3 Sunflower
4 Maize
Explanation:
Exp:D Water containing cavities in vascular bundles are found in maize. In monocot stem vascular bundles are collateral and conjoint vascular bundles. - In the vascular bundles, cambium is absent between xylem and phloem. So these are closed vascular bundles. - In the xylem, protoxylem is towards the centre and metaxylem is towards the periphery. So it is endarch xylem. - In the protoxylem some of the cells, disintegrate and form into a lysigenous cavity called as protoxylem lacuna eg. maize (lacuna in maize).

The meristem responsible for extra stellar secondary growth in dicot stem is
1 inter fascicular cambium
2 intra fascicular cambium
3 inter calary meristem
4 phellogen
Explanation:
Exp:D Phellogen is defined as the meristematic cell layer responsible for the development of the periderm. The extrastelar regions grow simultaneously. The growth of extrastelar region is initiated by the formation of cork cambium of phellogen.

Arrangement of vascular bundles and bundle sheath tissue in Monocot stem
1 Ring and Sclerenchyma
2 Scattered and Sclerenchyma
3 Scattered and Parenchyma
4 Scattered and Collenchyma
Explanation:
Exp:B The arrangement of vascular bundles and bundle sheath tissue in Monocot stem scattered and sclerenchyma. On the other hand, in dicots stem, the vascular bundles are arranged in the form of one or two broken circular rings and they have a definite shape.

The characters restricted to monocot Stem \& Leaf respectively
1 Trichomes and Bulliform cells
2 Lysigenous cavity and Bulliform cells
3 Trichomes and Lysigenous cavity
4 Bulliform cells and Lysigenous cavity
Explanation:
Exp:B Monocots stem possess Lysigenous cavity. These cavities help in storage of water, gases and oil in stem. Like stems of monocots, their leaf also passes water storage bodies, that is spread among the leaf epidermal cells called as Bulliform cells.
