b. ⊕☿$P_{3+3}A_{3+3}G_{(\underline 3 )}$
c. ⊕☿$P_{2+2}A_6G_{(\underline 3 )}$
d. ⊕☿$P_3A_{3+3}G_{(\underline 3 )}$

Answer 1

Hint: The angiosperms that are flowering plants are classified into different families. This classification is solely on the basis of floral characters. The flowers consist of mainly four parts or regions namely petals, sepals, stamens and pistil. The stamens and pistil are the male and female reproductive organs of a flower respectively.

Complete answer:
The flowers of the family Liliaceae are actinomorphic, bisexual, perianths are six, stamens of the Liliaceae family are six, and they are polyandrous, the gynoecium of the Liliaceae family is tricarpellary, a syncarpous ovary, the stigma of the Liliaceae family is trilobed, placentation is axile.

Some features of the plants of this family are listed below :
• The lily family, Liliaceae, consists of about 254 genera.
• The Liliaceae consist of characters like the are monocotyledonous, perennial, herbaceous, bulbous flowering plants with simple trichomes (root hairs) and contractile root.
• The inflorescence of the Liliaceae family is generally indeterminate (lacking terminal flower).
• The flowers of the Liliaceae family are Hermaphroditic, actinomorphic (radially symmetric) or slightly zygomorphic (bilaterally symmetric),
• The androecium of the Liliaceae family consists of Six stamens in two trimerous whorls, with free filaments,
• The Gynoecium of the Liliaceae family consists of Superior ovary (hypogynous), syncarpous (with fused carpels), with three connate (fused) carpels, and is trilocular.

Hence, the correct answer is option (B).

Note: The flowers of family liliaceace have radial symmetry, bisexual i.e. having both male and female reproductive organs, they have six tepals in two whorls that are united (gamophyllous),they have six free stamens attached to tepals (epiphyllous), the gynoecium is tricarpellary, united (syncarpous) with a superior ovary.
