The growing portion at the apex of the shoot is the terminal bud of the plant, and by the continued development of this bud and its adjacent tissues, the stem increases in height. Lateral buds and leaves grow out of the stem at intervals called nodes; the intervals on the stem between the nodes are called internodes.

What supports the stem of a plant?
Ground tissue helps support the stem and is called pith when it is located towards the middle of the stem and called the cortex when it is between the vascular tissue and the epidermis.
Which part of plant supports plant?
The stem is the part that stays above the ground. A stem usually bears leaves, fruits plus flowers. It distributes the nutrients and minerals all the way from the plant to the leaves. Furthermore, the stem is the support system of the plant.
Which part of the flower provides support to the stem?
6. Receptacle. The receptacle is where the stem connects to the rest of the flower. It provides support to the rest of the flower.
What tissue supports the stem?
Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.
What protects the stem of a tree?
Bark is the outermost layers of stems and roots of woody plants.
What are the parts of stem?
The stem is divided into two parts; nodes and internodes. Nodes are where buds grow into leaves, stems, or flowers and internodes are the parts of the stem in between the nodes (see Figure 8). In most plants, stems are found above the ground, but for some plants, such as potatoes, stems are also found below the ground.
What gives support to the plant?
The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider (our skeleton is on the inside of our body, rather than on the outside like insects or spiders). The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin.
Which part of the plant provides support to upper part of plant?
► Roots anchor the plants in the soil and absorb nutrients and water that are needed by the rest of the plant. ► Stems support the upper part of the plant and act as a transport system for nutrients, water, sugar, and starches.
What is the node of a plant stem?
A node is an area on a stem where buds are located (figure 6). It is a site of great cellular activity and growth. It is here that small buds develop into leaves, stems or flowers. When pruning, it is important to locate a plant’s nodes.
What is the pith of a plant?
Pith, or medulla, is a tissue in the stems of vascular plants. Pith is composed of soft, spongy parenchyma cells, which in some cases can store starch. In eudicotyledons, pith is located in the center of the stem. In monocotyledons, it extends also into flowering stems and roots.
What does the xylem do?
Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water-conducting function of xylem is one of the major distinguishing features of vascular plants.
What is cortex in plants?
cortex, in plants, tissue of unspecialized cells lying between the epidermis (surface cells) and the vascular, or conducting, tissues of stems and roots. Cortical cells may contain stored carbohydrates or other substances such as resins, latex, essential oils, and tannins.
What is cortex and pith?
Ground Tissue: The ground tissue of a stem is divided into two regions, the cortex and the pith. The cortex is located to the outside and/or around the vascular bundles, while the pith is locate in the center of the stem. Both the cortex and pith are composed mainly of parenchyma cells.
How does the cortex support plant?
The cortex forms layers of cells that constitute cork. It is responsible for the transportation of materials into the central cylinder of the root through diffusion and may also be used for food storage in the form of starch. The innermost layer of the cortex is the endodermis.
What is mesophyll in plant?
Mesophyll is the internal ground tissue located between the two epidermal cell layers of the leaf; and is composed of two kinds of tissues: the palisade parenchyma, an upper layer of elongated chlorenchyma cells containing large amounts of chloroplasts; and the spongy parenchyma, a lower layer of spherical or ovoid …
What is the role of phloem?
While the main role of the phloem tissue is to transport carbohydrates from sources to sinks through the sieve elements, phloem is also composed of parenchyma cells, which play a key role in the storage of water, non-structural carbohydrates and storage proteins (Rosell 2016).
What is Kranz anatomy?
Kranz anatomy can be described as two distinct concentric layers of chlorenchyma cells, formed by a bundle sheath containing most of the chloroplasts, surrounded by an outer layer consisting of a small number of mesophyll cells.
What are phloem tubes?
Phloem is the vascular tissue in charge of transport and distribution of the organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body. It is typically composed of three cell types: sieve elements, parenchyma, and sclerenchyma.
What are xylem tubes?
The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels. Vessels: Lose their end walls so the xylem forms a continuous, hollow tube.
What transports xylem?
The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root.
Does phloem provide support?
Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. Provide mechanical support. Does not provide mechanical support. Xylem is the dead tissue at maturity, but no cell contents.
Which would provide mechanical support to stem?
Xylem is primarily instrumental in the conduction of water and solutes, and also for mechanical support.

What is between xylem and phloem?
The total amount of xylem tissue is more. The total amount of phloem tissue is less. It consists of tracheids, vessel elements, xylem parenchyma, xylem sclerenchyma and xylem fibres. It consists of four elements: companion cells, sieve tubes, bast fibres, phloem fibres, intermediary cells and the phloem parenchyma.
What is found between xylem and phloem in the stem?
So, the correct option is ‘Conjunctive parenchyma‘.
What transports phloem?
Phloem transports carbohydrates, produced by photosynthesis and hydrolysis of reserve compounds, to sink tissues for growth, respiration and storage. At photosynthetic tissues, carbohydrates are loaded into phloem (Rennie and Turgeon 2009), a process that raises the solute concentration.
