Hair are found in the inflorescences of Zea mays are the modification of:
- Style
- Stigma
- Spathe
- Filaments
The Correct Option is A
Solution and Explanation
Hair found in the inflorescences of Zea mays, commonly known as maize or corn, are a modification of filaments. These hair-like structures, often referred to as silk, emerge from the female flowers' ovules or kernels. They play a crucial role in the pollination process. Each filament is essentially a style that captures and guides pollen to the stigma, allowing fertilization to occur. This adaptation ensures the successful reproduction of the plant.
So, the correct option is (A): Style

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.
