Question

What is the function of the tip of a leaf

Answer 1

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.

Answer 2

The function of the tip of a leaf are:

• The leaf blade, also known as the lamina, might be the flattened section as for leaf that may be separated into three distinct regions: The furthest section as for lamina from the site of extension about leaf towards the stem is the tip either apex.
• The tip as for the leaf blade is the apex. Acuminate apices feature a long, thin, sharp apex and linear to convex sides, with an extreme angle reduced to 45 degrees. Acute apices feature a discernibly pointed tip, an extreme angle of 45 to 90 degrees, and sides that are straight to convex. Mucronate apices possess a point at the tip that is short, sharp, and abrupt.
• Cuspidate apices feature an extended, sharp-pointed tip or apex that is compressed quickly and violently (a sharp, fixed point). Obtuse apices have a rounded or abrupt end, and linear to convex sides with a larger than 90-degree angle. The tip of rounded sepals is curled to make a broad, sweeping arc.
• Truncate apices have a tip that seems to be chopped off practically at a right angle to the midrib, resulting in a flat-topped or squared-off appearance. A schematic notch in an orbit or obtuse apex characterizes retuse apices. An apex of emarginate tips has a shallow and wide notch. These are only a handful of the countless shapes and sizes that leaf apices may assume.
