Cell elongation in internodal regions of the green plants takes place...
Explanation:
Cell elongation in internodal regions of green plants takes place due to gibberellins.
Gibberellins are a group of plant hormones that promote stem elongation, germination, and flowering. They are produced in the apical meristem and young leaves of plants.
Mechanism of cell elongation:
1. Gibberellins stimulate the production of enzymes that break down the cell wall, specifically the hemicellulose and pectin components of the wall.
2. This allows the cells to expand and elongate.
3. Gibberellins also stimulate the production of new cell wall components, such as cellulose and lignin, which contribute to cell wall strength and stiffness.
Role of gibberellins in internodal elongation:
1. In internodal regions, gibberellins stimulate the growth and elongation of the cells.
2. This results in the elongation of the stem and the internodes, which contributes to the overall growth of the plant.
3. Gibberellins also promote cell division in the apical meristem, which provides a continuous source of new cells for elongation.
In conclusion, gibberellins play a crucial role in cell elongation and internodal growth in green plants.
