Morphology of Flowering Plants Test 41

Asparagus officinalis, commonly known as Asparagus or Garden Asparagus is a herbaceous, perennial flowering plant genus belonging to family Liliaceae. It is native to Europe and western temperate Asia It is widely cultivated as a vegetable crop. Young asparagus shoots are commonly edible. So, the correct answer is 'Liliaceae'.

Smilax is a genus of flowering plants belonging to family Liliaceae. In most of the plants belonging to family Liliaceae, the leaves are exstipulate (stipules are inconspicuous or entirely absent) and the venation is usually parallel (the veins present within the leaves are parallel to each other). But in Smilax, the leaves are stipulate i.e stipules are present. Stipules are outgrowths present on either side of the base of a petiole. In smilax, the venation is reticulate (veins are interconnected and forms web-like structure). So, the correct answer is 'Smilax'.

The inflorescence is the process of arrangement of flowers in a plant. In Allium cepa, commonly known as onion is a species of plant belonging to family Liliaceae. The inflorescence of onion is Umbellate cyme which is a type of mixed inflorescence. In this inflorescence, the central flower is subtended by umbellate branching (  it consists of a number of short flower stalks which spread from a common point) and initial monochasial cyme (terminal flower with one flower below) to dichasial cyme (simple cyme)

Oryza sativa, commonly known as Asian rice or rice is the plant species belonging to family Poaceae. It has been cultivated since ancient times. It is one of the most important grains since it is consumed by half of the world population. The oil deriving from rice, namely rice bran oil (RBO), is one of the most commonly used cooking oils in Asia, and the major by-product of the rice milling industry. So, the correct answer is 'Poaceae'.

Cicer arietinum, commonly known as chickpea, gram or Bengal gram is an annual legume belonging to family Fabaceae or Papilionaceae. The chickpea seeds are rich in protein. It is one of the earliest cultivated legumes and it is native to Middle East countries. It is used for human consumption and it is also used as animal fodder because it is rich in protein content. So, the correct answer is 'Papilionaceae'.

The Fabaceae or Leguminosae, commonly known as pea, bean or legume family are a large and economically important family of flowering plants. It includes trees, shrubs, perennial or annual herbaceous plants which can be easily recognised by fruits (legume). It includes a variety of pulses such as chickpea, garden pea and important agricultural and food plants such as soya bean, beans, alfalfa, peanut etc.

Hydrophytes, in which root system is rooted in the soil and their leaves float on the surface of water. In these leaves, stomata are present on the upper epidermis or surface. Such leaves are called Epistomatous leaves. Eg:Nelumbo, Nympheae.

So, the correct option is ‘Upper surface’.

In grasses and many monocots, the leaf base (petiole) is broad and surrounds the stem as an envelope. Such a leaf base is known as sheathing leaf base. In grasses such as wheat, maize and grass, the sheathing leaf base protects the intercalary meristem. Hence, the plants belonging to family Poaceae have sheathing leaf base.
