Which among the following is not correct about different modifications...
Explanation:
The correct answer is option 'C': Stems in corn grow above the ground.
Explanation:
Stems are the main structural parts of plants that provide support, conduct water and nutrients, and serve as a site for photosynthesis. They can be modified in various ways to perform different functions. Let's discuss each option and understand why option 'C' is incorrect.
1. Weak stems are aerial stems that are further classified into trailers, creepers, and climbers:
- Weak stems are those that lack rigidity and cannot support the plant upright on their own.
- These stems need support from other structures, such as nearby plants or trellises.
- Weak stems are further classified into three types:
- Trailers: These are weak stems that grow horizontally along the ground without any specialized structures for support.
- Creepers: These are weak stems that grow horizontally along the ground and produce special structures called adventitious roots at nodes to anchor themselves.
- Climbers: These are weak stems that grow vertically and require some support to climb. They may use tendrils, hooks, or thorns to cling to supporting structures.
2. Stems in rhizome, tuber, and bulb grow under the ground:
- Rhizome: It is a modified stem that grows horizontally underground and gives rise to new shoots and roots.
- Tuber: It is a swollen underground stem that stores food and nutrients. Examples include potatoes and yams.
- Bulb: It is a modified underground stem that consists of fleshy storage leaves. It serves as a food reserve for the plant. Examples include onions and garlic.
3. Stems in corn grow above the ground:
- This statement is incorrect. Corn (Zea mays) is a monocot plant, and its stem, commonly known as the corn stalk, grows above the ground.
- The corn stalk is tall and robust, providing support to the plant and bearing the leaves, tassels, and ears of corn.
4. In some plants, stems are modified into thorns for defense:
- This statement is correct. Some plants have modified their stems into thorns as a defense mechanism against herbivores.
- Thorns are sharp, pointed structures that deter animals from feeding on the plant.
In conclusion, the correct answer is option 'C': Stems in corn grow above the ground. Corn stems grow above the ground and are not modified into any other specialized structures.
The correct answer is option 'C': Stems in corn grow above the ground.
