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 .
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.
Monocot flowers occur with parts having multiples of three; usually there are three stamen, three petals and three sepals (six tepals), and usually just one stigma. [18] However stamens in twos can be found in Cypripedioideae while single fertile stamens can be found in Philydraceae , Zingiberaceae , and as gynostemium in Orchidacaea .
A floral diagram is a schematic cross-section through a young flower. [1] It may be also defined as “projection of the flower perpendicular to its axis”. [ 3 ] It usually shows the number of floral parts, [ Note 2 ] their sizes, relative positions and fusion.
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]
Typha / ˈ t aɪ f ə / is a genus of about 30 species of monocotyledonous flowering plants in the family Typhaceae.These plants have a variety of common names, in British English as bulrush [4] or (mainly historically) reedmace, [5] in American English as cattail, [6] or punks, in Australia as cumbungi or bulrush, in Canada as bulrush or cattail, and in New Zealand as raupō, bullrush, [7 ...
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.
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.
