Conjoint and closed vascular bundles are found in

Vascular bundles (VB) are the components of vascular tissue system in plants. They are also called as ‘fascicle’. They are the part of TRANSPORT system in plants. It is one of the PRIMARY tissue systems in plants. More than that is a perfect example for a COMPLEX tissue system in plants. (Complex tissue = composed of more than one type of cells). The present articles discribes the types of vascular bundles in plants. Components of vascular bundles Vascular bundle consists of TWO main parts. @. Xylem: the water conducting tissue @. Phloem: the food conducting tissue Xylem and phloem are complex tissues, i.e., they contain different types of tissues. Components of xylem: Tracheids, Vessels, Xylem fibres and Xylem parenchyma. Components of phloem: Sieve cells/Sieve tubes, Companion cells, Phloem parenchyma, Phloem fibres (bast fibres). How vascular bundles originate in plants? The elements of xylem and phloem are always organized in groups called VASCULAR BUNDLES. The vascular tissue system develops from the pro-cambium of apical meristem (pro-meristem). During apical growth, the pro-cambium produce a layer of longitudinally elongated cells which are slender and with dense cytoplasm. These strands during the course of time differentiate into xylem and phloem and organize into vascular bundles. You may also like NOTES in...

Introduction A leaf is the principal component of the plant, which is found above the ground. One of the essential characteristics of a leaf is that it is generally green in colour. Leaves are the structure responsible for photosynthesis, and leaf anatomy plays an essential role in this process. This article deals with Leaf anatomy, i.e. the internal structure of a leaf, parts and functions. Leaf anatomy, i.e., the internal structure of a leaf, comprises the epidermal tissue, the mesophyll tissue and the vascular tissue. The epidermis is the outermost layer; mesophyll is the middle layer, and vascular bundles are scattered. Leaf The leaf is known as the kitchen of the plant. They are the primary organ responsible for photosynthesis, which is how the plant obtains its energy or food. The presence of chlorophyll gives them their green hue. Function of Leaf • Photosynthesis: The most crucial function of a leaf is photosynthesis. They include chloroplasts that help in photosynthesis. Phloem tissue transports the prepared food to other sections of the plant • Help plants to breathe- The epidermis of the leaf contains guard cells that manage and regulate the microscopic holes under the surface of the leaves, allowing the plant to breathe. Stomata are the name for these pores. Stomata control the flow of water into and out of the cell. It is also in charge of the gas exchange throughout the epidermis • Food storage: The leaves of several plants have been adapted to store food. Su...

Vascular bundles are long, fluid channels of vascular tissues found in the stems, Xylem is the dead, permanent tissue occupying the center of the vascular bundle. In contrast, the phloem is the living, permanent tissue surrounding the xylem. In addition to the xylem and phloem, vascular tissues called Thus, vascular bundles typically represent the organization of xylem and phloem and their association with other accessory transporting tissues. The vascular bundle arrangement differs in monocot and dicot plants. Arrangement of Vascular Bundle In Stems Vascular bundles are arranged differently in monocot and dicot plants. In monocots, they are randomly scattered, with most of them near the outer edge just below the epidermis. The bundles are surrounded by large In Roots They have a radial vascular bundle. In monocot In Leaves Like stems and roots, the leaf also contains vascular bundles composed of xylem and phloem. When the vascular bundle of the Functions of Vascular Bundle Xylem • Transport water with minerals from roots to other • Transport hormones such as abscisic acid and cytokinin Phloem • Transport food and other organic nutrients from leaves to all other plant parts. They are commonly called the ‘eating’ tubes in plants. • Provide the path for the translocation of peptides, proteins, and mRNAs involved in Both xylem and phloem form specialized vascular cell types such as tracheary elements in the xylem and sieve elements in the phloem. In addition, they together pr...

In monocot stem vascular bundles are found irregularly scattered in the ground tissue. Towards the periphery, the bundles are smaller in size, while towards the centre, they are larger in size. The smaller bundles are younger, while the larger ones are older. Hence, the arrangement is described as centrifugal.
