Detailed explanation-1: -The arrangement of veins over the leaf is called venation. These can be in a network form called reticulate venation or in straight form without intersecting with each other called parallel venation.

Detailed explanation-2: -The lines on the leaf are called veins.

Detailed explanation-3: -If your plant leaves look like someone was doodling squiggly lines, It’s likely that your plant has a leafminer infestation. 1 Leafminers are the larvae of various beetles, flies, moths, and sawflies.

Detailed explanation-4: -The leaf contains some lines which may be visible from both sides of a leaf, and they are referred to as leaf veins. The central vein often found in the middle of a leaf is called the midrib, also called the primary vein. The other veins branching from the midrib are called the secondary veins.

Detailed explanation-5: -Veins are lateral extensions that develop from the midrib of the leaf and extend towards the leaf margin. Veins contain the conducting tissues called the xylem and phloem.
