The vascular bundles in the stems of most dicots are conjoint, collateral and open. In each of these bundles
Xylem and phloem are on the same radius with phloem towards the pith and xylem towards the pericycle without a strip of cambium between them
Xylem and phloem are on the same radius with xylem situated towards the pith and phloem situated towards the pericycle and a strip of cambium separates the two
Xylem completely surrounds the phloem on all sides but the two are separated by the cambium
Phloem completely surrounds the xylem and a strip of cambium separates the two
Answers (1)
Conjoint: The term "conjoint" refers to the arrangement of different types of vascular tissues within a single bundle. In dicots, the vascular bundles are conjoint, meaning they contain both xylem (responsible for water and mineral transport) and phloem (responsible for the transport of organic nutrients) tissues within the same bundle.
Collateral: The term "collateral" describes the arrangement of xylem and phloem tissues within the vascular bundle. In collateral bundles, the xylem and phloem tissues are arranged adjacent to each other, with the xylem located towards the inner side and the phloem towards the outer side of the bundle.
Closed: The term "closed" refers to the presence of a cambium layer within the vascular bundle. The cambium is a meristematic tissue that is responsible for secondary growth in plants. In closed vascular bundles, a cambium layer is present between the xylem and phloem, allowing for the formation of secondary xylem (wood) and secondary phloem.
Therefore, option 2 is correct.
