Structure and physiology. The domesticated crop originated in the Americas and is one of the most widely distributed of the world’s food crops. Piliferous Layer or Epiblema. Primary structure of monocotyledonous root – Maize root The maize provides a structure for the beans to climb, eliminating the need for poles. The flowers are unisexual, containing either stamens or ovary but not both. Its fruit-wall and seed-coat are fused into a single layer. Structure of Maize Grain . The male inflorescences are on terminal branches and the female inflorescences are lower down, on lateral branches. The Maize grain can be taken as an example of monocotyledon seed. STUDIES ON THE STRUCTURE OF THE MAIZE PLANT HUGH C. CUTLER Chicago Natural History Museum AND MARIAN C. CUTLER There is a basic pattern for most grasses and this pattern is repeated through-out each plant, in reproductive as well as vegetative parts. This is best understood by studying their internal structure by cutting sections (transverse or longitudinal or both) of the part to be studied. The main axis of the maize plant bears leaves and buds on opposite sides of successive nodes. The maize grain is a small one-seeded fruit called the caryopsis.In maize grain the seed coat (testa) is fused with the fruit wall (pericarp).Externally, the maize grain is yellow in colour and somewhat triangular in shape. In different parts of the plants, the various tissues are distributed in characteristic patterns. The closer the spacing, the more plants there will be per unit area.

Photo name: Maize (Corn) Plant Diagram Picture category: Plants Image size: 66 KB Dimensions: 436 x 594 Photo description: This maize plant diagram shows both the male and female flowers of what is commonly known as corn. There is a small tube near the top of the grain. Unlike other plants in which FNR has been studied, maize is a C4 plant and therefore contains two differentiated photosynthetic cell types (Schuster et al., 1985). The maize plant is often 3 m (10 ft) in height, though some natural strains can grow 13 m (43 ft). Primary Structure of Monocot Root-maize Root . This The width of rows and the spacing of plants in the row determines the plant population. This page was last edited on 18 August 2020, at 20:09. The outermost layer of the root is known as piliferous layer. Find free pictures, photos, diagrams, images and information related to a wide range of different plants right here at Science Kids. Corn is used as livestock feed, as human food, as biofuel, and as raw material in industry. Back to Flower Structure: Maize Plant: Next Drawing > Maize (Zea mays). The transverse section of the monocot root (maize) shows the following plan of arrangement of tissues from the periphery to the centre. The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. Corn, (Zea mays), also called Indian corn or maize, cereal plant of the grass family and its edible grain. The stem is commonly composed of 20 internodes of 18 cm (7 in) length. In maize, mesophyll cells perform predominantly LET, while bundle sheath cells have very low photosystem II … All structured data from the file and property namespaces is available under the Creative Commons CC0 License; all unstructured text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply. Maize grain is not a seed , but a single-seed fruit. The beans provide the nitrogen to the soil that the other plants use, and the squash spreads along the ground, blocking the sunlight, helping prevent the establishment of weeds. A leaf, which grows from each node, is generally 9 cm (3 1 ⁄ 2 in) in width and 120 cm (3 ft 11 in) in length. The long, crowded inflorescences bear flowers of only one sex. Structure and Function of Maize and Bean Maize The External Structure . The grain is monocotyledonous and endospermic.
