Cross Section Of Leaf Xylem And Phloem Vascular bundles (veins) like the stem, the leaf contains vascular bundles composed of xylem and phloem (figure 3.4.2.6 − 7 3.4.2. 6 − 7). when a typical stem vascular bundle (which has xylem internal to the phloem) enters the leaf, xylem usually faces upwards, whereas phloem faces downwards. the conducting cells of the xylem (tracheids and. Xylem and phloem form the vascular system of a plant. xylem transports water and minerals, while phloem transports food. the vascular system of plants consists of the xylem and phloem. they are somewhat like blood vessels in animals, but plants transport materials using two tissues rather than one. here is a look at what xylem and phloem are.
Cross Section Of Leaf Xylem And Phloem Lower epidermis: a protective layer of cells. the lower epidermis produces a waxy cuticle too in some plant species. the lower epidermis contains pores called stomata that allow carbon dioxide and oxygen to move in and out of the plant respectively. stomata: tiny pores (small holes) surrounded by a pair of sausage shaped guard cells. To identify xylem and phloem under a microscope, here’s what you need to do: step 1: take a thin cross section of the stem or leaf that you want to examine. step 2: stain the section with a suitable stain. safranin is a commonly used stain for xylem, while phloem stains are typically a combination of toluidine blue and basic fuschin. The xylem is transporting water and dissolved minerals from the roots up to the leaf, while the phloem is transporting sugars made in the leaf to other regions of the plant. draw a cross section of a mesophytic leaf, labeling each structure or tissue with its name and function. consider simplifying the image to use as an easy reference. The xylem consists of tracheids and vessels, which transport water and minerals to the leaves. the phloem transports the photosynthetic products from the leaf to the other parts of the plant. a single vascular bundle, no matter how large or small, always contains both xylem and phloem tissues. figure \(\pageindex{1}\): xylem and phloem: this.

They also contain vascular structures that transport water from the roots into the cells that carry out photosynthesis. 1. the plant’s vascular tissues—xylem and phloem—transport water to the leaves and carry glucose away from the leaves. anyone who cares for plants could probably tell you that pouring water directly onto the leaves isn. In the root, the xylem forms a cross like structure in the centre which is surrounded by phloem vessels. this arrangement adds strength to the root as it pushed through the soil. within the leaf, the xylem vessels are found towards the top of the vascular bundle with the phloem vessels found underneath.
