Which of the following is the name for the type of venation where the main vein runs through the center of the leaf, with smaller veins branching off of it?

Venation is the arrangement of veins in a leaf, which serves to transport water, nutrients, and sugars throughout the plant. Pinnate venation is the name for the type of venation where the main vein or midrib runs through the center of the leaf, with smaller veins branching off of it on either side like the feather of a bird. This type of venation is typically found in dicot plants such as roses, hibiscus, and palm trees.

Pinnate venation is an adaptation for the efficient transport of water and nutrients to the entire leaf. The midrib provides a strong central support structure for the leaf, while the smaller veins branching off of it increase the surface area of the leaf for efficient gas exchange with the atmosphere.
