C) Trimerous, actinomorphic, polyandrous, superior ovary, axile placentation
D) Bisexual, Zygomorphic, gamophyllous, inferior ovary, marginal placentation
E) Unisexual, actinomorphic. trilocular, inferior ovary, axile placentation

Answer 1

Hint: Liliaceae are the lily family that has flowers with 3 sepals and 3 petals fused and epipetalous with 6 stamens and axile placentation. The ovary is superior and polyandrous. They include lilies and tulips.

Step by step answer: The Liliaceae is a family under order Liliales. It includes plants that are angiosperms and monocots. They are ornamental plants that are grown for their attractive flowers.
The flower has both sexes. They are bisexual and are trimerous as they have three petals. They are actinomorphic, meaning regularly symmetrical and can be divided by any plane. They are polyandrous, meaning all stamens on the flower are free. A superior ovary is the position of ovary present at the tip of the thalamus from where the remaining floral whorls arise from the base of the ovary. Placentation is the arrangement of the ovules or placentae inside the ovary. The axile placentation occurs in bi or multilocular ovary. Carpels are fused along with sides and margins and thus chambers or lobes are formed. The number of chambers corresponds to the number of carpels in the flower. Ovules are attached to the central axis where the septa of all carpels meet.
Hence, the correct answer is option C.

Note: Epiphyllous condition means filaments are fused with six sepals. The sepals and petals are identical in size and colour and thus, considered as 6 tepals. There are six stamens ideally but some species lack anthers on some stamens.
