What is the midrib of a leaf called?
The midrib is also called as midvein, where it contains the vascular bundles, such as xylem and the phloem, which helps in the transport of water, food, and the nutrients, apart from the midvein in the leaf, lateral veins are also present, which helpful for protection, and transport.
Which part of a leaf is an organ?
Organs exist in all higher biological organisms, they are not restricted to animals, but can also be identified in plants. For example, the leaf is an organ in a plant, as is the root, stem, flowers and fruits. In this section the leaf is used as an example of an organ.
What type of tissue is the midrib made of?
The midrib contains two types of supporting tissues: vascular tissue, including xylem and phloem, and mechanical tissue, including sclerenchyma and collenchyma. The vascular system is mainly composed of xylem and phloem, which distributes and interconnects both root and shoot systems.
What is the function of the midrib in a leaf?
Answer and Explanation: The function of midrib in a leaf is to give the leaf support so it won’t bend and break in half.

What are the function of midrib and side veins in the leaf?
Midrib along with lateral veins forms leaf’s skeleton and provides mechanical support to leaf. It also helps to transport water, minerals to different cells of leaf. It transports synthesised food from leaf to stem where from it is carried to different parts of plant.
What is lamina and midrib?
1) The leaf blade (lamina) is also known as the epipodium, the wide and flat portion of the leaf where photosynthesis occurs. The midrib is the central prominent vein on the lamina that contributes to the transport of water, minerals, and various leaf cells.
