The celery plant is characterized by enlarged, tender, edible petioles or leaf stalks. The petioles are broad, with sheathing bases, and consist mostly of parenchyma and collenchyma strands. These are associated with vascular bundles under the epidermis in the abaxial surface which is prominently ridged, whereas the adaxial surface is smooth.
The three parts of a typical foliage leaf are: (1) The Leaf-Base (Hypopodium) (2) The Petiole (Mesopodium) and (3) The Lamina (Epipodium). Foliage leaves are essential for the plant as leaf is the seat of several very important physiological processes like photosynthesis (which is related to the green colour), transpiration and respiration.
21 lis 2023 · A petiole is a structure of a plant that connects the stem of the plant to the blade of the leaf. An example of a petiole is the stem-like structure that is sometimes attached to leaves when...
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.
17 gru 2016 · The petiole is the stalk that supports a leaf in a plant and attaches it to the stem. Many people often call it a stem, which is incorrect. A stem is the part of the plant that serves as the main source of support and produces nodes and roots, and that’s not what we observe in petioles.
7 lut 2022 · Our results showed that leaf area has the strongest influence on petiole anatomical traits, more than temperature, precipitation and plant height, emphasizing the supportive and mechanical role of this part of the leaf. Petioles tend to be longer and have a circular outline in larger leaves.
Definition. A petiole is the stalk that connects a leaf blade to the stem of a plant. This structure is crucial for supporting the leaf, allowing it to effectively capture sunlight and engage in photosynthesis. The petiole also serves as a conduit for transporting water and nutrients between the leaf and the rest of the plant, playing a vital ...
