The region of attachment of the leaf with the stem is called the -----...
Since leaf has three parts
1) leaf apex
2) lamina
3) leaf base
petiole is stalk of leaf .in question it is asked region den answer will be leaf base which is more accurate as compared to petiole bcoz in ques parts is not asked .

The region of attachment of the leaf with the stem is called the Petiole.
Explanation:
The attachment of a leaf with the stem is an important structural feature of plants. It is the region where the leaf is connected to the stem, allowing the leaf to receive water, nutrients, and other essential substances from the stem. This region is known as the petiole.
- The Petiole:
The petiole is a slender stalk-like structure that connects the leaf blade (lamina) to the stem. It is responsible for supporting the leaf and positioning it correctly to receive sunlight for photosynthesis. The petiole varies in length, depending on the plant species, and can be long or short. Some plants have no petioles, and their leaves are directly attached to the stem.
- Function of the Petiole:
1. Support: The petiole provides support to the leaf, holding it in the proper position to maximize exposure to sunlight.
2. Transportation: The petiole contains vascular tissues, such as xylem and phloem, which transport water, minerals, and sugars between the leaf and the stem.
3. Flexibility: The petiole allows the leaf to move and adjust its position in response to environmental conditions, such as wind or light intensity.
4. Protection: In some plants, the petiole may have thorns or other defensive structures to deter herbivores from feeding on the leaf.
- Other Leaf Parts:
1. Lamina: The leaf blade or lamina is the broad, flat, expanded part of the leaf. It is the main site of photosynthesis and gas exchange.
2. Leaf Margin: The leaf margin refers to the edge or boundary of the leaf blade. It can be smooth, toothed, lobed, or have other specific shapes.
3. Leaf Base: The leaf base is the part of the leaf where it attaches to the petiole or directly to the stem. It may be rounded, tapered, or have a specific shape.
In conclusion, the petiole is the region of attachment between the leaf and the stem. It has various functions, including support, transportation, flexibility, and protection.
