Leafs are flat parts of plants, which grow from stem, twig, branch, etc. They make food for the plant through a process named photosynthesis, by taking CO2 and releasing O2 to the atmosphere. You can study its structure by two ways, seeing its external parts and its internal structure (also its cells).
Externally: apex (or leaf point), upper epidermis) which protect the cells), margin (the outer edge), veins (they carry water, minerals and food to the plan), lower epidermis (covered by small holes known as stomata), midrib and the petiole (or stem).
Internally: cutin (a waxy surface), upper epidermis, palisade cell, chloroplast (contains chlorophyll for the photosynthesis), air space, spongy mesophyll cell (were the respiration takes place), lower epidermis, stoma (opens to allow gases in and out)
A stipule is a small, leaf-like structure found at the base of a leaf stalk. Its main function is to protect the leaf bud as it grows and to help regulate the flow of nutrients to the leaf.
A leaf has a flat, thin structure with an outer epidermis layer that protects the leaf. Inside the leaf, there are layers of cells known as mesophyll, which contain chloroplasts for photosynthesis. The veins of the leaf transport water and nutrients throughout the leaf.
Because the leaf structure do not have the ability to store the starch molecules
A compound leaf is a leaf structure where the leaf blade is divided into multiple leaflets attached to a single leaf stem, called a rachis. Each leaflet may resemble a small, individual leaf but is part of a larger compound leaf structure.
A new stem, leaf, flower, or branch may develop at the axil of a leaf.
The structure of a leaf is skeletal
the leaf like structure of a seed is embryo
draw internal leaf
The cuticular and the stomatal level of the leaf structure affects foliar fertilization.
