The maize and Sorghum vulgare seed (grain) is a
(a) Monocot and albuminous
(b) Monocot and non-albuminous
(c) Dicot and non-albuminous
(d) Dicot and albuminous
Solution
Maize is commonly known as corn which is a cereal grain and gets domesticated by indigenous peoples in several areas of southern Mexico. It consists of a leaf stalk in the plant which helps in the production of pollen inflorescence. Sorghum is broom corn which is a species of grass that is cultivated for its grain.
Complete answer:
The maize and Sorghum vulgare seed is monocot and albuminous. The monocot seed has only one cotyledon and includes all the true grains which include wheat and rice. Albuminous seeds have special food storage tissue which is known as endosperm. The process of pollination that occurs in these flowers is known as geitonogamy. In geitonogamy, the flowers are actually on the same plant and the pollination takes place between them which is known as self-pollination. Pollen grain in maize starts germinating on the stigma and the other grains migrate from pollen grain into the style. The ovules enter the ovary of the inside pistil where the process of fertilization takes place. This transition is regulated by the reproductive stage in maize which is indeterminate.
Sorghum is composed of phenolic acids and other flavonoids which makes it one of the highest food sources. The plant has a defence mechanism towards ultraviolet radiation and diseases. It shows defences against herbivores and pests which are correlated with the activity of antioxidants. Some species are modified for heat tolerance and nitrogen efficiency which makes them the staple food for the rural and poor people.
So, the correct answer is 'Monocot and albuminous'.
Note:
Maize is a member of the grass family whose scientific name is Zea Mays. Maize was dispersed into lower Central America and was moved to the inter- Andean valleys of Columbia. The first maize grew 25 millimetres long in corn cobs.
