a. Poaceae
b. Liliaceae
c. Asteraceae
d. Fabaceae

Answer 1

Hint: Flowering plants also called angiosperms are a large group of terrestrial plants. Like all other plants and animals, they are classified into families based on their characteristics such as leaves shape, position and venation, inflorescence, number of anther, stigma and style, etc.

Complete answer:
The lily family, also known as ‘Liliaceae’, has approximately 250 genera and more than 4000 species of flowering plants in it. They are found all over the world, mainly distributed in the Northern Hemisphere. The plants in this family are monocotyledonous (seed has only one cotyledon) and perennial. They have large and colourful flowers having 6 stamens and one superior ovary, and are mostly pollinated by insects. The flowers can be arranged over the stem (inflorescence), or can be single or in clusters at the top of the stem. They have both characters of female (gynoecium) and male (androecium). Three fused carpels (syncarpous), one style, and one stigma (tri-lobed) are present.

The inflorescence can be cymose or umbellate. In cymose inflorescence, the first flower develops from the top of the stalk of the flower (growing region). In umbellate inflorescence, a large number of small flowers (pedicles) grow together but are separated from a common point. Both sepals and petals are of the same size and look like two separate whorls. The stamens are present in two groups having three stamens in each group. Usually, a single groove is present in the pollen.
It has contractile roots that help to withstand the plant intact in dry seasons as well.

The leaves of these family plants are linear, having parallel veins (parallel venation) to the edges. Leaves are single and are arranged on the stem alternatively. Sometimes they are also present in clusters in a rosette at the base of the flower.

Hence, the correct answer is option (B).

Note: The lily family is an important ornamental family, having a great economic importance, and is mainly grown for its large, colourful and attractive flowers, such as lilies and tulips. They are often used for decoration purposes. Some species of this family are poisonous and if eaten could have harmful effects on the health of humans and animals.
