Leaf is an external organ of the plant
The external structures/parts of the flower are: 1. Dermal tissue 2. Cuticle 3. Ground tissue 4. Air spaces 5. Guard cell 6. Stomata
at the external layer is the lamina which is the flat leaf. there is also the network of veins which provides the minerals.furthermore is the petiole which holds the leaf the the main branch.lastly is the cuticle which prevents excessive loss of water of the plant. this is the internal structure of the leaf courtesy from www.wikipedia.org HI
The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.

the internal make up of a leaf isn't really complex the chloroplast is the main component in photosynthesis because it captures sunlight.
The structure of a leaf is skeletal
To draw a transverse section of a leaf, first obtain a small, thin slice of the leaf using a sharp blade or razor. Place this slice on a slide and add a drop of water or mounting medium. Then cover with a coverslip and observe under a microscope, adjusting the focus to view the internal structures of the leaf like epidermis, mesophyll, and vascular bundles. Sketch what you see, labeling the key structures.
The colorful, leaf-like structures of flowers are called petals.
A transverse section of a leaf is a cut made perpendicular to the leaf's long axis, revealing its internal structures such as the epidermis, mesophyll layers, and vascular tissues. This section allows for the observation of the arrangement and organization of different cell types within the leaf.

A lobe of a leaf is a division or section that extends outward from the main part of the leaf blade. Lobes can vary in shape and size depending on the plant species, and they are common in leaves with palmate or lobed structures.
