Morphology of Flowering Plants Test 42

Allium cepa, commonly known as bulb onion or common onion is a vegetable which is the most widely cultivated species belonging to family Liliaceae. Allium sativum, commonly known as garlic is the species of flowering plant belonging to family Liliaceae. Aloe vera is a succulent plant belonging to family Liliaceae. Allium cepa, Allium sativum and Aloe vera are familiar examples of family Liliaceae. So, the correct answer is 'Allium sativum, Allium cepa and Aloe vera'.

Zea mays, commonly known as corn or maize is a cereal grain belonging to the family Poaceae. In Zea mays, the inflorescence of female flowers is spadix of spikelets arising from the axil of a lower leaf. A large number of spikelets are arranged closely on the fleshy axis. It remains surrounded by a few large hyaline bracts called spathes. Each spikelet is two-flowered and has protective glumes. Of the two, usually the upper flower is fertile and the lower one aborts. Lodicules are absent.

Disciflorae is an artificial group of plants based on Bentham and Hooker classification. The group Disciflorae are polypetalous and dicotyledonous. It comprises flowers having prominent disc-shaped thalamus below the ovary. The ovary is superior. Fabaceae or Leguminosae is a large and economically important family of flowering plants. Fabaceae belongs to the series Disciflorae

Allium cepa, commonly known as the onion is the species of an economically important family of monocotyledonous flowering plant (Liliaceae). Helianthus annuus, commonly known as the sunflower is a dicot belonging to family Asteraceae. Brassica juncea is the species of flowering plants belonging to family Brassicaceae and it is also a dicot. Arachis hypogaea, commonly known as groundnut is a dicot and belongs to the family Fabaceae. Hence, Helianthus annuus, Brassica juncea and Arachis hypogea are dicotyledonous; whereas, Allium cepa is a monocot. So, the correct answer is 'Allium cepa'.

Fabaceae or Papilionaceae, commonly known as a legume, pea and bean family is an economically important family of flowering plants. In Fabaceae, the flowers are medianly zygomorphic (bilateral symmetry), bisexual. Ascending imbricate aestivation (posterior petal overlaps) is seen. Petals are five, polypetalous (flowers having distinct or separate petals).

Fabaceae or Leguminosae, commonly known as the legume, pea and bean family are a large and economically important family of flowering plants. It includes trees, perennial or annual herbaceous plants, shrubs which can be easily recognised by their fruit (legume) and their compound leaves. Stamens are 10, diadelphous (united by filaments into two groups i.e.,(9)+1. Posterior stamen is free and nine are fused at the filaments

Liliaceae or Lily family includes species of an economically important family of monocotyledonous flowering plants. In Liliaceae, the flower is pedicellate, actinomorphic (radial symmetry), bisexual, hypogynous (stamens and other floral parts are situated below carpels), trimerous (calyx, corolla and stamens are present in sets of 3). In Liliaceae, the gynoecium is Tricarpellary, syncarpous, ovary superior, trilocular or unilocular with two ovules, axile placentation, style simple; stigma trilobed.

Fabaceae or Leguminosae, commonly known as the legume, pea and bean family is a large and economically important family of flowering plants. It includes trees, shrubs and annual or perennial herbaceous plants which can be easily recognised by their fruit and compound leaves. In Fabaceae, the stamens are 10, diadelphous (stamens are united by their filaments to form two groups i.e.,(9)+1 ). Posterior stamen is free and filaments of nine are fused to form a sheath around the ovary

Liliaceae or Lily family is the species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. The Liliaceae are widely distributed, but mainly in the temperate regions of Northern hemisphere. The Liliaceae are ecologically diverse. Species of Liliaceae bloom at various times from spring to late summer.

Fabaceae or Papilionaceae is a large and economically important family of flowering plants containing papilionaceous corolla. In Fabaceae, the petals are 5 - the outermost posterior petal (vexillum or standard) is the largest petal and it encloses all the essential organs, two lateral petals (wings or alae) and the two anterior and innermost petals are united to form a boat-shaped structure known as the keel or carina.
