Pentamerous, actinomorphic flowers, bicarpellary ovary with oblique septa, and fruit a capsule or berry, are characteristic features of:
- Asteraceae
- Brassicaceae
- Solanaceae
- Liliaceae
The Correct Option is C
Solution and Explanation
Pentamerous Flowers: Solanaceae flowers typically have five petals, five sepals, and five stamens. This pentamerous arrangement is a common feature within the Solanaceae family.
Actinomorphic Flowers: Flowers in Solanaceae exhibit radial symmetry, which means you can divide the flower into equal halves in multiple ways, such as a wheel.
Bicarpellary Ovary with Oblique Septa: In the Solanaceae family, the ovary typically has two carpels, and these carpels have oblique septa, which are partitions or divisions within the ovary that are not parallel to its axis.
Fruit as a Capsule or Berry: The fruits produced by members of the Solanaceae family are often in the form of capsules or berries. For example, tomatoes and eggplants are both part of the Solanaceae family and produce berry-type fruits.
The other options:
Asteraceae: This family typically has composite flowers (multiple small flowers in a head), not pentamerous flowers.
Brassicaceae: Brassicaceae family members, such as mustard and cabbage, usually have four-petaled flowers, not pentamerous.
Liliaceae: Liliaceae family members often have trimerous (parts in threes) flowers and various fruit types (e.g., capsules or bulbs), which do not align with the description provided in the question.
Therefore, the combination of pentamerous, actinomorphic flowers, bicarpellary ovary with oblique septa, and fruit in the form of a capsule or berry is a characteristic feature of the Solanaceae family, making option (C) the correct answer.

Morphology of Flowering Plants
Morphology in flowering plants tells us that every plant has two systems such as a root system and a shoot system. The root system digs deep into the ground and structures a system of its own. On the other hand, the shoot system is the one that is above ground level and includes various plant parts.
Root System
The descending part of the plant grows under the soil roots. During the germination process, the radicle from the seed grows earthward and branches out. The branches along with the primary root are called the root system. Roots lack chlorophyll and therefore they are not green in color. Roots are positively geotropic and hydrotropic, that is, they grow downwards ground and water, and negatively phototropic, which is growing away from light.
There are three types of root systems found in plants are as follows:
- TapRoot System
- Fibrous Root System
- Adventitious Root System
Shoot System
The stem is also an essential element of the plant. It is the ascending portion of the plant axis that bears branches, flowers, leaves, and fruits, as well as aiding in water and mineral conduction. It is the plant's aerial portion, brought about from an embryo's plumule or germinating seeds. Young stems are ordinarily green, but they finally turn woody and brown.
