Question

Tricarpellary, syncarpous gynoecium is found in flowers of-
A. Liliaceae
B. Solanaceae
C. Fabaceae
D. Poaceae

Answer 1

Hint: This family is considered a typical monocot family and reflects the basic monocot stock that has originated from many families and is of polyphyletic origin. They also have cultivated garden plants that are popular.

Complete answer:
Option A is correct. The Liliaceae are a family of around 2500 species of herbaceous perennial monocots. It is also known as the 'family of lilies'. With axile placentation gynoecium, they have syncarpous, tricarpellary, trilocular, superior ovary. This family's plants are essential food and medicine sources, such as Aloe vera, Colchicine, etc.
Option B is incorrect. The genus Solanaceae is sometimes referred to as the potato family. They have gynoecium syncarpous, bicarpellary, bilocular, superior ovary, axile placentation. In various parts of the world, many solanaceous are major weeds. Their value lies in the fact that they can host plant-grown pathogens or diseases, so their existence increases the loss of yield or the quality of the product harvested.
Option C is incorrect. A Fabaceae family, comprising many economically important plants, is a large family within the plant kingdom. The family Fabaceae, as it belongs to the family of peas or legumes, is also known as Leguminosae or Papilionaceae. Superior ovary, monocarpellary, unilocular, single, short-style and flat, hairy-stigma gynoecium are usually present. The plants of this family are distinctive and have root nodules containing symbiotic bacteria that fix nitrogen, capable of turning atmospheric nitrogen into fixed nitrogen or ammonia.
Option D is incorrect. Grasses, a large and almost ubiquitous family of monocotyledonous flowering plants, are known as Poaceae or Gramineae. And encompasses the natural grassland of cereal grasses, bamboos and grasses and organisms grown in lawns and pastures. Typically, the above is commonly referred to as grass. They have monocarpellary carpels 3, according to some writers, of which 2 are abortive, superior ovary, single ovule unilocular, basal placental, short or absent style; feathery or papillate stigmas and branched gynoecium.

So, the correct answer is Option A.

Note: The majority of Liliaceae are valuable ornamental plants, which are widely cultivated for their attractive flowers and are primarily involved in cut flowers and dry bulb floriculture. When consumed, certain plants are toxic and can have adverse health effects on humans and domestic pets.
