How do you margin
the leaves differ?
Answers
Answer:
The flattened part of the leaf is the leaf blade or lamina,which can be subdivided into three discrete regions: The tip or apex is the part of the lamina farthest removed from the point of attachment of the leaf to the stem. The base of the leaf is the part of the lamina that is closest to the point of attachment of the leaf to the stem. The margin is the perimeter of the leaf between the apex and base.
The form, ormorphology, of leaves is often characteristic of individual species of plants and, like the reproductive features, is an important base of plant identification.
Some plants have a more or less cylindrical petiole that joins the base of the leaf to the stem, while others lack a petiole and are called sessile. The midrib is the prominent vein that subdivides the leaf into two halves from base to apex.
