Question

The plant of Triticum aestivum is
(a) Haploid
(b) Diploid
(c) Tetraploid
(d) Hexaploid

Answer 1

Hint: Triticum aestivum is characterized by having collated roots, with seminal and adventitious roots. The seminal roots are people who originate, in numbers from 3 to eight, directly from the embryo; these are thin, very rich in the root, and really branched hairs.

Complete answer:
The tribe Triticeae consists of 18 genera which are divided into two sub-groups, the Triticale and thus the Hordenine. The most general genera within the subgroup Triticina are Triticum, Aegilops, Secale, Agropyron, and Haynaldia. Plants of the Triticum are annuals with spring or winter forms.
T. aestivum L. is hexaploid (AABBDD) with an entire 42 chromosomes (2n=42) , sixfold seven chromosomes) . Similarly, the varied wheat species also contain some multiple of the essential haploid set of seven chromosomes. New wheat cultivars are either tetraploid (durum, (AABB) or hexaploid (common and club-types, (AABBDD) .

Additional Information: Other features:
The ears have a brittle or tough rachis. Generally, they're four-sided. The spikelets have two to five florets. They show the features such as short ligule and spikelets that are sometimes hairy, and a smooth, bald, usually hollow culm, 0.7-1.6 meter tall Pithy filling may be a smaller amount common than a hollow culm. Each floret can produce one grain (caryopsis) , i.e. is distichous. The glumes are keeled, on the highest as an example in T. aestivum, containing serrated lemmas, long and either bearded or unbearded. Grains are loosely enclosed (naked wheat) and are easily threshed. The rachilla has thin walls and doesn't disarticulate on maturity. In Spelta (spelled wheat) the grains are hulled by the spelt. For this reason, they can't be dropped during the tactic of threshing. In Triticeae the starch granules are distinctive from each other. The wheat meal could also be an important product.
So, the correct answer is 'Hexaploid'.

Note:
- The young stems are utilized in the treatment of biliousness and intoxication.
- The ash is employed to get rid of skin blemishes. The fruit is antipyretic and sedative.
- The sunshine grain is antihydrotic. it's utilized in the treatment of night sweats and spontaneous sweating.
-The seed is claimed to contain sex hormones and has been utilized in China to market female fertility.
- Of the cultivated wheat, common wheat, T. aestivum, is economically far and away from the foremost important.
