Leaf of dicotyledonous plants
The leaf of dicotyledonous plants is characterized by netted venation and a variety of shapes, often with a petiole and a complex margin.
01
Trichomes
Small hairs on the surface of the leaf that can perform protective functions.
02
Palisade mesophyll
The upper layer of mesophyll cells containing many chloroplasts, actively participating in photosynthesis.
03
Vascular bundle
A complex of tissues including xylem and phloem, responsible for the transport of substances.
04
Guard cells
Cells surrounding the stomata, controlling their opening and closing to regulate gas exchange.
05
Stoma
Openings through which gas exchange occurs.
06
Cuticle
A waxy layer that reduces water loss.
07
Upper epidermis
The outer protective layer of cells on the upper surface of the leaf.
08
Spongy mesophyll
The lower layer of mesophyll cells containing intercellular spaces for gas exchange.
09
Xylem
Conductive tissue that transports water and minerals.
10
Phloem
Conductive tissue that transports organic substances.
11
Bundle sheath
A layer of cells surrounding the vascular bundle.
12
Lower epidermis
The outer protective layer of cells on the lower surface of the leaf.
13
Collenchyma
Tissue that provides flexibility and support to the leaf.
