Flashcards in Characteristics Of A Leaf Deck (6)
Apex's function of the leaf
The leaf apex is a protruding part of a leaf where water droplets accumulate, and droplet separation occurs during drainage.
Midrib's function of the leaf
A midrib provides strength throughout the leaf, keeping it upright and sturdy in the wind. Chlorophyll is the green pigment that absorbs sunlight. Veins transport water and glucose around the plant. The petiole attaches the leaf to the plant's stem.
Lamina's function of the leaf
The leaf blade, or lamina, consists of a central tissue, called the mesophyll, surrounded on either side by upper and lower epidermis. Patterns of the leaf veins are often characteristic of plant taxa and may include one main vein and various orders of smaller veins, the finest veinlets infiltrating
Margin's function of the leaf
The edge of the leaf is called the margin. Parts of a leaf: A leaf may seem simple in appearance, but it is a highly-efficient structure. Petioles, stipules, veins, and a midrib are all essential structures of a leaf. Within each leaf, the vascular tissue forms veins.
Vein's function of a leaf
Veins are composed of xylem and phloem cells embedded in parenchyma, sometimes sclerenchyma, and surrounded by bundle sheath cells. The vein xylem transports water from the petiole throughout the lamina mesophyll, and the phloem transports sugars out of the leaf to the rest of the plant.
