The discussion moves to the basic parts of a leaf, which include the lamina, petiole, and sheath. The instructor explains the differences between complete and incomplete leaves, highlighting that incomplete leaves lack a sheath and may attach directly to the stem.
00:10:00 - 00:15:00
The session continues with the identification of leaf shapes based on the lamina's form. Various leaf shapes are introduced, such as orbicular, peltate, and oblong, with examples provided for each type. The instructor explains the characteristics that define these shapes, including their dimensions and how they relate to specific plants.
00:15:00 - 00:24:16
The instructor further elaborates on additional leaf shapes, including ovate, triangular, deltoid, and cordate. Each shape is described in detail, with comparisons made to similar shapes. The session concludes with a discussion on the diversity of leaf shapes found in nature, encouraging students to observe and identify these shapes in their surroundings.
