Which among the following statements is incorrect about monocotyledono...
Incorrect Statement: Buliform cells that help in the curling of leaves are absent in monocot leaf.
Explanation:
Monocotyledonous plants, also known as monocots, have certain unique characteristics that differentiate them from dicotyledonous plants. One of these characteristics is the presence of buliform cells in the leaves, which help in leaf rolling or curling under certain circumstances.
Function of Buliform Cells:
Buliform cells are specialized cells found in the upper layer of the leaf called the epidermis. These cells are responsible for leaf rolling, which helps in the conservation of water during dry conditions. When water availability is limited, the buliform cells lose turgidity and become flaccid. This causes the leaf to curl, reducing the exposure of the lower leaf surface to the environment, thereby minimizing water loss through transpiration.
Other Correct Statements:
1. Epidermis covers the entire plant and protects the plant from external damage:
The epidermis is the outermost layer of cells that covers the entire plant body, including the leaves, stems, and roots. It serves as a protective barrier against mechanical injury, pathogens, and excessive water loss.
2. Vascular bundles in monocot stem are neither radial nor conjoint:
In monocot stems, the vascular bundles are scattered throughout the ground tissue. They are arranged in a complex manner and are referred to as atactostele. Unlike dicot stems, where vascular bundles are arranged in a circular pattern and may be either radial or conjoint, monocot stems lack a definite arrangement of vascular bundles.
3. In a monocot stem, pericycle is absent:
The pericycle is a layer of cells present in the outermost region of the vascular cylinder of dicot stems. It gives rise to lateral roots and lateral meristems. However, in monocot stems, the pericycle is absent, and the formation of lateral roots occurs differently.
Therefore, option A is incorrect as buliform cells are indeed present in monocot leaves.
