Axile placentation is observed in
Axile placentation is observed in
China rose, Beans and Lupin
Tomato, Dianthus and Pea
China rose, Petunia and Lemon
Mustard, Cucumber and Primrose
The Correct Option is C
Solution and Explanation
Axile placentation refers to the arrangement of ovules in the central column of a compound ovary. It is seen in plants where the ovary is divided into multiple chambers and the ovules are attached to a central axis. To identify which of the given sets of plants exhibit axile placentation, we need to understand the typical placentation types observed in these plants:
- China rose (Hibiscus): Exhibits axile placentation.
- Petunia: Exhibits axile placentation.
- Lemon (Citrus): Exhibits axile placentation.
Therefore, the correct set among the given options that exhibits axile placentation is China rose, Petunia and Lemon.

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

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.
