Cross-section of a monocot root. Note the lack of any pattern in the arrangement of the vascular bundles. For the background to this list, see List of the vascular plants of Britain and Ireland .
Floral diagram of Anagallis arvensis. [1]: 307 The dot represents the main axis, green structure below is the subtending bract.Calyx (green arcs) consists of five free sepals; corolla (red arcs) consists of five fused petals.
Allium crenulatum (Asparagales), an onion, with typical monocot perianth and parallel leaf venation Onion slice: the cross-sectional view shows the veins that run in parallel along the length of the bulb and stem. The monocots have, as the name implies, a single (mono-) cotyledon, or embryonic leaf, in their seeds.
Rhizomes are root-like stems which usually grow laterally underground or on the ground and sprout new individuals. Most plants that produce rhizomes are monocots (grasses, bamboo, ginger, galangal, turmeric, orchids, irises, lotus); these include the families: Poaceae, Zingiberaceae, Orchidaceae, Iridaceae, and Nelumbonaceae.
The cross-section of a barley root. Root morphology is divided into four zones: the root cap, the apical meristem, the elongation zone, and the hair. [5] The root cap of new roots helps the root penetrate the soil. These root caps are sloughed off as the root goes deeper creating a slimy surface that provides lubrication.
Cross-section of a flax plant stem: 1. Pith 2. Protoxylem 3. Xylem I 4. Phloem I 5. Sclerenchyma 6. Cortex 7. Epidermis. In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. [1]
Orchis comes from the Greek for "testicle", from the shape of the paired root tubers of many Mediterranean species. [1] [109] [110] 707 genera, worldwide, especially in the tropics [1] [111] Largely herbaceous plants that generally grow in soil or on other plants.
Acorus is a genus of monocot flowering plants.This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots.
