Describe the mechanisms underlying primary and secondary growth in arboreal dicotyledonous plants, elucidating the distinctive physiological and anatomical processes involved in each phase.

Answer rating: 100% (QA)

Primary Growth in Arboreal Dicotyledonous Plants 1 Apical Meristems Primary growth is initiated by the activity of apical meristems which are located at the tips of stems and roots The apical meristems give rise to primary tissues leading to elongation of the plant in both height and depth 2 Cell Division The apical meristems undergo continuous cell division through mitosis producing cells that differentiate into various primary tissues Primary tissues include the primary xylem and phloem as well as the primary meristem tissues protoderm ground meristem and procambium 3 Elongation Elongation of the plant occurs as new cells are produced and elongate The primary tissues differentiate and contribute to the development of primary organs such as stems leaves and roots 4 Root Growth In roots primary growth leads to the elongation of the root tip allowing the plant to explore the soil for nutrients and water Secondary Growth in Arboreal Dicotyledonous Plants 1 Vascular Cambium Formation Secondary growth occurs in mature dicotyledonous plants contributing to an increase in girth or diameter The vascular cambium a lateral meristem ...
