The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be sessile.
7 lut 2022 · Petioles are one of the most efficient structures in plants and represent an essential connection between the stem and the plant’s photosynthetic machinery, the leaf blade (Niinemets and Fleck, 2002; Faisal et al., 2010; Levionnois et al., 2020). The primary function of a petiole is to provide mechanical support to self-hold and adjust leaf ...
17 gru 2016 · Petiole Function. Since leaves are responsible for fueling plants through photosynthesis, the petiole serves to transport the energy made in the leaf to the rest of the plant. It also serves to transport nutrients and water that are absorbed by the roots and passed up through the xylem, to the leaf.
21 lis 2023 · A petiole is a stalk that attaches the blade of a leaf to the main stem of the plant. There are many functions of a petiole, and this lesson provides a brief overview of what a petiole is and...
Stipules and stipels may, in some cases, function to protect the young, developing leaf primordia. They often are small and fall off (are “caducous”) soon after leaf maturation. In some taxa, stipules or stipels may be highly modified into spines or glands.
The petiole is a stalk that connects the blade with the leaf base. The blade is the major photosynthetic surface of the plant and appears green and flattened in a plane perpendicular to the stem. Read More. study of fern leaves. In fern: Leaf stalk.
1 kwi 2021 · Petioles are important plant organs connecting stems with leaf blades and affecting light-harvesting leaf ability as well as transport of water, nutrient and biochemical signals.
