Exarch and tetrach are a feature of
Answers
Explanation:
Vascular bundles in monocot root are radial in arrangement. There are eight bundles each of xylem and phloem. Hence, the condition is described as polyarch. Xylem is described as exarch
In monocot stem, xylem is described as endarch and presence of only two protoxylem and two metaxylem vessels in each bundle. So, it is not polyarch.
In dicot root, vascular bundles are described as radial and tetrarch. There are four bundles each of xylem and phloem occurring alternately. Xylem is described as exarch
Dicot stem vascular bundles are eight in number, arranged in form of a broken ring. The vascular bundles are conjoint, collateral and open. Xylem is on the inner surface and phloem on the outer surface. Xylem is described as endarch
So, the correct answer is 'Monocot root'
Answer:
these are xylem tissues of vascular plants . these type of tissues are found in monocot roots of vascular bundles which are in radical arrangements .
these help in transportation of water and other minerals through roots. that support plant to prepare food .
