It is the organ that lies below the surface of the soil. Roots can also be aerial i.e. growing above the surface of the ground or aeratedwhich meansfloating over the surface of the water. Roots are responsible for providing the stems and the leaves with adequate water and nutrients for their growth. Related: Can roots strangle a tree? Root Functions Roots form a major Anchor and Support The root system of the plant provides physical support by anchoring the plant body to the soil. Many plants can stand erect for hundreds of years because their roots grow deep into the soil and hold the plants strongly in place. Absorption and Conduction Roots have root hairs through which roots absorb water and nutrients from the soil which are essential for the plant growth. Roots have a capability of absorbing inorganic nutrients against the concentration gradient. After the water and nutrients are absorbed, they are moved upwards to stem and leaves. In deserts, roots grow deep into the permanent water...

32.11: Asexual Reproduction

\( \newcommand\) • • • • Asexual Reproduction Many plants are able to propagate themselves using asexual reproduction. This method does not require the investment required to produce a flower, attract pollinators, or find a means of seed dispersal. Asexual reproduction produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place. Traditionally, these plants survive well under stable environmental conditions when compared with plants produced from sexual reproduction because they carry genes identical to those of their parents. Plants have two main types of asexual reproduction: vegetative reproduction and apomixis. Vegetative reproduction results in new plant individuals without the production of seeds or spores. Many different types of roots exhibit vegetative reproduction. The corm is used by gladiolus and garlic. Bulbs, such as a scaly bulb in lilies and a tunicate bulb in daffodils, are other common examples of this type of reproduction. A potato is a stem tuber, while parsnip propagates from a taproot. Ginger and iris produce rhizomes, while ivy uses an adventitious root (a root arising from a plant part other than the main or primary root), and the strawberry plant has a stolon, which is also called a runner. Figure \(\PageIndex\): Roots: Different types of stems allow for asexual reproduction. (a) The corm of a garlic plant looks similar to (b) a tulip bulb, but the corm is solid tissue, while the bulb c...

30.11: Plant Development

\( \newcommand\) • • • • • Learning Objectives • Discuss the attributes of meristem tissue and its role in plant development and growth The adult body of vascular plants is the result of meristematic activity. Plant meristems are centers of mitotic cell division, and are composed of a group of undifferentiated self-renewing stem cells from which most plant structures arise. Meristematic cells are also responsible for keeping the plant growing. The Shoot Apical Meristem (SAM) gives rise to organs like the leaves and flowers, while the Root Apical Meristem (RAM) provides the meristematic cells for the future root growth. The cells of the shoot and root apical meristems divide rapidly and are considered to be indeterminate, which means that they do not possess any defined end fate. In that sense, the meristematic cells are frequently compared to the stem cells in animals, which have an analogous behavior and function. Meristem tissue and plant development Meristematic tissues are cells or group of cells that have the ability to divide. These tissues in a plant consist of small, densely packed cells that can keep dividing to form new cells. Meristematic tissue is characterized by small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces. Meristematic tissues are found in many locations, including near the tips of roots and stems (apical meristems), in the buds and nodes of stems, in the cambium between the xylem and phloem in dicoty...

What are plant roots? Function & types

• Biology • Plant Biology • Plant Root Plant Root Have you ever heard the expression “putting down your roots”? Well, although you may not have physical roots, it means that you are establishing yourself in one place, as a plant would do by putting down roots! Roots are important plant organs that help them stay put and carry out a number of other functions as well.

Secondary growth

In many lateral meristems, secondary growth increases the width of the plant root or stem, rather than its length. As long as the lateral meristems continue to produce new cells, the stem or root will continue to grow in diameter. In Because this growth usually ruptures the In nonwoody plants [ ] Secondary growth also occurs in many nonwoody plants, e.g. Abnormal secondary growth [ ] • Thompson, N.P. and Heimsch, C. 1964.

Plant embryonic development

Plant [ ] Following fertilization, the zygote and endosperm are present within the ovule, as seen in stage I of the illustration on this page. Then the zygote undergoes an asymmetric transverse apical cell The small apical cell is on the top and contains most of the hypocotyl, shoot apical meristem, and cotyledons. basal cell The large basal cell is on the bottom and consists of a large hypophysis suspensor. Eight cell stage [ ] After two rounds of longitudinal division and one round of transverse division, an eight-celled embryo is the result. apical embryo domain, gives rise to the shoot apical meristem and cotyledons. The second domain, the central embryo domain, gives rise to the hypocotyl, root apical meristem, and parts of the cotyledons. The third domain, the basal embryo domain, contains the hypophysis. The hypophysis will later give rise to the radicle and the root cap. The last domain, the suspensor, is the region at the very bottom, which connects the embryo to the endosperm for nutritional purposes. Sixteen cell stage [ ] Additional cell divisions occur, which leads to the sixteen cell stage. The four domains are still present, but they are more defined with the presence of more cells. The important aspect of this stage is the introduction of the protoderm, which is meristematic tissue that will give rise to the epidermis. Globular stage [ ] The name of this stage is indicative of the embryo's appearance at this point in embryogenesis; it is spherical or globul...
