What do you mean by the morphology of leaves?
Morphology is the study of science that deals with the form and structure of an organism. Morphology of leaves deals with the study of the structural features and parts of a leaf.
What is the arrangement of veins and veinlets on the lamina of a leaf is called?
Solution: The arrangement of veins and veinlets on the lamina of a leaf is called venation. There are two types of venation, reticulate and parallel venation.
What is the morphology of a plant?
For plants, plant morphology or phytomorphology is the study of the physical form and external structure of plants, whereas plant anatomy is the study of the internal plant structure, mostly at the cellular/microscopic level.
What are leaf arrangements?
leaf arrangement. phyllotaxy – the arrangement of leaves on an axis. 2-ranked – arranged in 2 rows, one on either side of the stem or central axis. alternate – an arrangement with 1 leaf attached at each node. distichous – 2-ranked, with alternate leaves arranged on opposite sides of a stem, not spirally arranged.
What are the principal veins of a leaf?
The principal veins may arise as side branches from the midrib or may develop from the base of the lamina parallelly to the midrib. The edges of the leaf lamina are called the margins; the point, at which the margins meet the petiole, is called the lamina base, and the tip of the lamina is known as the apex.
What is venation in a leaf?
The arrangement of veins and the veinlets in the lamina of the leaf is called venation. You can see different types of venation in different plants. But generally, there are TWO types of venation. Reticulate Venation: When the veinlets are irregularly arranged and form a network called reticulate venation.
What is the leaf of a leaf?
Leaves are flattened lateral outgrowths of the stem which are generally green m colour and form the foliage of a plant. A typical leaf of two main parts: an expanded blade or lamina, and a stalk called the petiole, by which the leaf is attached to the stem.
What is the flat part of a leaf called?
Lamina: The lamina is the flat and green part of the leaf with veins and veinlets. Lamina is commonly known as Leaf Blade. The photosynthesis process occurs on this part of the leaf. Main Leaf Veins – In the middle of the lamina (leaf blade), a prominent mid-rib or main vein connects with the petiole.
