Q.Venation is a term used to describe the pattern of arrangment of

The lamina, or leaf blade, is traversed throughout by a system of veins and smaller veinlets that branch out from a central midrib. The specific term used to describe how these veins and veinlets are arranged within the lamina is venation. This term applies strictly to the pattern seen in the leaf blade, whether the veins form an interconnected network or run alongside one another, and it does not refer to how floral organs or flowers on an inflorescence are arranged. …

Every leaf blade, or lamina, is expanded and green, and it is crossed by a network of veins and finer veinlets that branch out from a prominent central vein, the midrib.

• These veins give the leaf blade rigidity and also act as internal channels that transport water, minerals and food materials through the lamina.
• The way this system of veins and veinlets is arranged within the lamina is precisely what the term venation captures. …

Method: Parse the Question's Own Vocabulary Instead of Recalling a Definition

Some MCQs can be solved just by breaking down the technical term itself, without recalling any grounding text at all.

The word venation is built from vein, so before even looking at the options, expect the correct answer to involve veins.

Now scan the four options for the word vein. Option (a), floral organs, makes no mention of veins. Option (b), flower in inflorescence, makes no mention of veins. Option (c), veins and veinlets in a lamina, contains the word veins directly, and lamina is the leaf blade, exactly where veins are found. Option (d), all of them, is only correct if (a) and (b) were also valid, which they are not.

Since only option (c) actually references veins at all, and venation is by definition about the pattern of veins, this option is correct almost by word-matching alone. …
