Root mucilage is made of plant-specific polysaccharides or long chains of sugar molecules. [1] [2] This polysaccharide secretion of root exudate forms a gelatinous substance that sticks to the caps of roots. [3] Root mucilage is known to play a role in forming relationships with soil-dwelling life forms.
Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage. [ 1 ]
Mucigel is a slimy substance that covers the root cap of the roots of plants. It is a highly hydrated polysaccharide, [1] most likely a pectin, which is secreted from the outermost (epidermal) cells of the rootcap. Mucigel is formed in the Golgi bodies of such cells, and is secreted through the process of exocytosis.
The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
Leaf size varies considerably, up to 100 mm (4 in) long, and 75 mm (3 in) wide. The leaves are arranged alternately along the stem, with no stipules, on petioles up to 45 mm (1.75 in). [6] [7] The inflorescences occur in the leaf axils and at the top of the stem and consist of panicles of 1-many flowers. The flowers are actinomorphic with 5 ...
The root cap protects the growing tip in plants. [1] It secretes mucilage to ease the movement of the root through soil, [1] and may also be involved in communication with the soil microbiota. [1] The purpose of the root cap is to enable downward growth of the root, with the root cap covering the sensitive tissue in the root. [2]
Mucilage secreting glands, as in the betel leaf; Glands secreting gum, resin, tannin, etc. Digestive glands secreting enzymes or digestive agents; Special water secreting glands at the tip of veins; External glands are commonly short hairs tipped by glands. They are water-secreting hairs or glands,
Two types of brace roots as shown in maize. Roots may develop from the embryo (contained in a seed) or post-embryonically (after germination). [1] In young plants, root functions such as anchorage and resource acquisition (finding and taking up water and nutrients) are carried out by embryonic roots.
