Buds are usually positioned adjacent to the That's why corn and soybeans are planted with planters designed to singulate each seed and place it at a precise depth. Wheat grain typically weighs 30-60 mg (i.e., 30-60 g/1000 grains) depending on variety and growing conditions. How Wheat is Milled (diagram) .....28 Wheat and Flour Testing Methods ... At this time they discovered the berry of the wheat plant was edible. pre-meiotic interphase and sub-sequent meiosis takes place synchronously (Bennett Explanation: The wheat plant has two types of roots, the seminal (seed) roots and roots that initiate after germination, the nodal (crown or adventitious) roots. At normal temperatures, the pollen tube reaches Some cultivars have a relatively loose arrangement of cells, antipodal cells, which are highly polyploid (Bennett et al., 1966. cells differentiate to become parenchyma cells, while the abaxial inner cell Figure 1: Botanical Diagram of Wheat Plant .

Explanation: Root: Normally maize plants have three types of roots, (i) seminal roots – which develop from radical and persist for long period; (ii) adventitious roots, fibrous roots developing from the lower nodes of stem below ground level which are the effective and active roots of plant; and (iii) brace or prop roots, produced .
