Root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

Bases, stems, and roots are the main components of words, just like cells, atoms, and protons are the main components of matter. In linguistics, the words "roots" is the core of the word. ... Hence a stem is a form to which affixes (prefixes or suffixes) have been added.

The Basic Structures of a Living Plant. Plants have a root system, a stem or trunk, branches, leaves, and reproductive structures (sometimes flowers, sometimes cones or spores, and so on). Most plants are vascular, which means they have a system of tubules inside them that carry nutrients around the plant.

The tissues are organized into specialized organs called roots, stems, and leaves. The internal vascular system, composed of xylem and phloem, is housed within these organs and connects the organs to one another.

Each plant contains a branched system of tubes called xylem, which is responsible for water transport from the roots (where it is taken up) to the leaves (where it is used in photosynthesis). Water flows up from the roots, through the trunk and branches, to the leaves, where it is used in photosynthesis.

A root hair, or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye and light microscope.

The root system consists of the roots, while the shoot system is made up of the stems and leaves. The shoot system conducts substances up and down the plant; the root system stores food and retrieves nutrients from soil. ... What is the difference between prop roots and stilt roots?

Root rot is a condition in which the roots of a plant begin to rot or decay. This condition can occur in both indoor and outdoor gardens, but is more common in indoor gardens, due to a combination of overwatering and poor drainage. When a plant's roots rot and the condition is left untreated, the plant will die.

Monocots have a root system that is composed of a network of fibrous roots as shown in the picture to the right. These roots all arose from the stem of the plant and are called adventitious roots. Also, woody trees that are not gymnosperms (pine, cedar, cypress, etc.) are dicots.

Plant organisation. Plant cells, tissues and organs are adapted to their functions. The stem, root and leaves form an organ system that transports substances into, around and out of a plant.

The difference between Origin and Root. When used as nouns, origin means the beginning of something, whereas root means the part of a plant, generally underground, that anchors and supports the plant body, absorbs and stores water and nutrients, and in some plants is able to perform vegetative reproduction.

Plant anatomy refers to the detailed structure of the plant: leaf, stem, roots, flowers, and fruits, while plant physiology is concerned with the processes that occur within the plant that account for it being alive and productive.

Why are roots essential for terrestrial plants? They absorb water and minerals needed for growth. ... All plant organs (such as leaves, roots, and stems) contain tissues from all three tissue systems.

Root vegetables grow underground at the base of a plant. ... Examples include bulbs (fennel, onions), corms (celery root, water chestnut), rhizomes (ginger, turmeric), tap roots (beets, carrots, parsnips), tuberous roots (sweet potatoes, yucca), and tubers (potatoes, yams).

Some roots, called adventitious roots, arise from an organ other than the root—usually a stem, sometimes a leaf. They are especially numerous on underground stems, such as rhizomes, corms, and tubers, and make it possible to vegetatively propagate many plants from stem or leaf cuttings. Certain adventitious roots,…

Background Maize (Zea mays) forms a complex root system comprising embryonic and post‐embryonic roots. The embryonically formed root system is made up of the primary root and a variable number of seminal roots.
