HW 25 Leaf Structure (1) Hillcrest High School; BIO 101 - Fall 2016. Sometimes leaves are divided into two or more sections called leaflets. The objective of this paper was to describe and compare the morphology and anatomy of mature leaves of Mikania glomerata Spreng., Porophyllum ruderale Cass. It consists of a flattened portion, called the blade that is attached to the plant by a structure called the petiole. Describes how leaves are made of several different kinds of specialized tissues. ��X�Y�0MaZϰ�aSKϟ�DX��?cX� ���c�:;�n&���n� ���S���,?���Č��o"Wj�o� ��I��4y$������vr%tn�戰8�1[|Cksφ�>�f���쒉�I���ܘ�&{�Q�£���#�f&B��o 0000042230 00000 n The leaf blade is connected to the stem by the petiole, which is the lifeline between the leaf and the rest of the plant.
