Morphology includes the study of the general structure of plants. Morphologists study the parts of a plant and how they are arranged and function. For example, when a seed of an angiosperm (flowering plant) germinates, the radicle of the seed embryo develops downward to form a root system. Growth in the length of the root […]

The ground tissues, the second of the primary developmental tissues, differentiate in the zone of maturation to form tissues called parenchyma, collenchyma, orsclerenchyma. The parenchymous tissues are the primary site of cellular metabolism. The organelles of parenchyma cells in different parts of the plant vary so that they can accommodate differences in metabolic functions. Cells […]

The procambium, the third of the primary developmental tissues, differentiates to form primary xylem and primary phloem as well as the vascular cambium. The vascular cambium produces cells that differentiate into secondary xylem and secondary phloem. It also regenerates the supply of cells in the vascular cambium. An example of xylem is the woody tissue […]
