D. Liliaceae

Answer 1

Hint: These are seen in ornamental plants like Tulipa and Gagea. Lilies and tulips in particular have symbolic and decorative value. They are colorful flowers. They are often bulbous geophytes. Perianth present has arranged in (3+3).

Complete answer:
- A tepal is one of the outermost parts of a flower (collectively called the perianth ). The perianth is the part of a flower which is situated outside the stamens and carpels. The non-reproductive part of the flower is called the perianth and it’s the structure that forms an envelope that surrounds the sexual organs.
- In monocotyledons, the two whorls are similar and often brightly colored. In dicotyledons, it consists of the calyx (sepals) and corolla (petals). Perianth occurs in the family Liliaceae, where there is no distinction between sepals and petals. Example onion, lily, etc.. Liliaceae, the perianth is 6 (3+3) which is arranged in two whorls of three each, and the perianth may be scarious or membranous.
- Solanaceae: The flowers are generally hermaphrodites. The flowers can be solitary ( existing alone ) or grouped into the terminal, cymose, or axillary inflorescences. The perianth is differentiated with a calyx and corolla (5+5). Examples: tomatoes, potatoes, eggplant, bell, and chili peppers.
- Fabaceae: The flowers are generally hermaphrodites. They have a short hypanthium, usually cup-shaped. The flowers often have five generally fused sepals and five petals that are free. Commonly called legume, pea, or bean family.
- Brassicaceae: This family of flowering plants is of economic importance and is generally referred to as the mustards, crucifers, or the cabbage family. Most are herbaceous plants. The flowers with four free sepals, four free alternating petals.
- Liliaceae: They are monocotyledons, perennial. Large flowers with parts arranged in threes: with six colored or patterned petaloid tepals. The perianth is undifferentiated.

So, the correct answer is option D.

Note:
A number of Liliaceae genera are popular cultivated plants in private and public places. Lilies and tulips appear frequently in paintings and the decorative arts. They are economically important products.
