Art of anatomy of dicotyledon leaf

Dicotyledon leaf. Illustration showing the anatomy and cell structure of a dicotyledon leaf. The lower surface of the leaf is seen at top. Stomata (brown, pores) are present on the lower epidermis through which gaseous exchange occurs. Under the one- cell thick epidermis, two layers of mesophyll cells are found. Spongy mesophyll (green) consists of loosely packed cells; a palisade layer (yellow) contains cells important in photosynthesis. At centre left, a leaf vein (vascular bundle) is surrounded by a bundle sheath (orange); within the sheath are xylem (pink) and phloem (white) cells which transport water and nutrients

Dicot Dicotyledon Epidermis Stoma Vascular Bundle

EDITORS COMMENTS
This print showcases the intricate artistry of a dicotyledon leaf's anatomy. The illustration provides a detailed glimpse into the cellular structure and composition of this botanical wonder. As we observe, the lower surface of the leaf is presented at the top, revealing an array of stomata or tiny brown pores on its lower epidermis. These stomata play a crucial role in facilitating gaseous exchange within the leaf. Beneath the delicate one-cell thick epidermis lies two layers of mesophyll cells. The spongy mesophyll, depicted in vibrant green hues, consists of loosely packed cells that contribute to various physiological processes within the leaf. Adjacent to it is a palisade layer represented by yellow shades, which houses cells essential for photosynthesis - nature's own solar panels. At center-left, our attention is drawn towards a prominent leaf vein or vascular bundle enveloped by an orange bundle sheath. This protective sheath encloses xylem and phloem cells responsible for transporting water and nutrients throughout the plant. Through this stunning artwork capturing both scientific precision and artistic beauty, Science Photo Library invites us to marvel at nature's ingenuity as we delve into the fascinating world of leaves and plants.
