What is the meaning of Leaf Blade?
Leaf blade means Leaf lamina OR Thin Leaf surface that is normally involved in photosymthesis . It is thin like Metallic blade or a shaving blade so it is called a leaf blade. It does not include the leaf stalk or Petiole . A leaf is an aerial and lateral outgrowth of the stem of a usually flat and dorsiventral anatomy. It functions mainly to manufacture food by photosynthesis and consists typically of a stalk also called petiole, a flattened BLADE, the lamina, and the leaf base. Strands of conducting and strengthening tissues, the veins, run through it. Their pattern, also called leaf venation, is a feature of characterization. Leaves may be simple, i.e. undivided or compound (composed of several parts called leaflets). The blade margin and the leaf arrangement at the stem are further features of characterization. click on the links below for more.
