Apart from different colours, textures, and shapes, did you observe that the leaves also have different types of lines on them? The two pictures printed in the book, showing two different arrangements of the lines on a leaf.

Question

Accepted Answer

Yes. These lines are called veins . The book shows two different arrangements of veins. The picture How the veins are arranged Leaves like this The long leaf on the left Many veins run side by side from one end of the leaf to the other. They do not cross. Banana, grass, maize, sugarcane The leaf on the right One thick vein runs down the middle. Smaller veins branch out from it like a net. Peepal, mango, banyan, hibiscus Why veins matter to us: They are one more thing that helps us tell plants apart. Two leaves may look the same size and colour, but the way their lines run can be quite different. Check it yourself: Turn a leaf over. The veins stand out on the back and you can feel them with your finger. This rough back is the side you use for the Leaf Autograph on the next page.
