Meristematic tissues are found in the tips of roots and shoots, as well as in the cambium layer of woody plants. These cells are undifferentiated, meaning they don't have a specific function yet. They have the potential to develop into any type of plant cell, depending on the signals they receive. This ability is crucial for plant growth and development.
Here's a breakdown of why other parts of the plant contain specialized cells:
* ルーツ： Contain specialized cells for absorption of water and nutrients, as well as structural support.
* ステム： Contain specialized cells for transporting water and nutrients, as well as providing structural support.
* Leaves: Contain specialized cells for photosynthesis, gas exchange, and protection.
* 花： Contain specialized cells for reproduction, including pollen grains, ovules, and petals.
したがって、植物の他の部分には特殊な細胞がありますが、分裂組織は、専門の細胞を持つ唯一の領域であり、植物が必要とするあらゆる細胞タイプに分化する準備ができています。
