In stems, the protoxylem lies towards the__and the metaxylem lies towards the__of the organ.
1 centre; periphery
2 periphery; centre
3 periphery; periphery
4 centre; centre
Explanation:
(a) The first formed primary xylum elements are called protoxylem and the later formed primary xylem is called metaxylem. In stems, the protoxylem lies towards the centre (pith) and the metaxylem lies towards the periphery of the organ. This type of primary xylem is
called endarch.

Apical and intercalary meristems are primary meristems because
1 they occur in the mature region of roots and shoots of many plants.
2 they made up of different kinds of tissues.
3 they involved in secondary growth.
4 they appear early in life of a plant and contribute to the formation of the primary plant body.
Explanation:
(d) Primary meristems are those meristems which originate from the embryonic meristem. They are located at the tips of stems, roots and appendages. Apical and intercalary meristems are primary meristem because they appear early in life of a plant and contribute to the
