What tissue is responsible for producing undifferentiated cells at stem tips, buds, and cambium layers?
The tissue that produces undifferentiated cells at stem tips, buds, and cambium layers is the meristematic tissue (a). The tissue responsible for producing undifferentiated cells at stem tips, buds, and cambium layers is the meristematic tissue. This type of tissue consists of actively dividing cells that contribute to plant growth. The cells in this tissue are mainly undifferentiated and can specialize to become any other type of cell. There are three types of meristematic tissue: apical (found at the tips of roots and shoots), lateral (found in the cambium layer), and intercalary (found at the base of leaves or internodes). Each of these plays a crucial role in helping the plant grow in different ways. The correct answer is Option A.
Meristematic Tissue
Meristematic tissue is responsible for the production of undifferentiated cells at various locations in plants. These tissues are essential for plant growth and development. The meristematic tissue is characterized by its ability to continuously divide and differentiate into different types of cells, contributing to the overall structure and function of the plant.
Types of Meristematic Tissue
There are three main types of meristematic tissue:
1. Apical Meristem: This type of meristematic tissue is located at the tips of roots and shoots. It helps in the elongation of the plant by producing new cells.
2. Lateral Meristem: Found in the cambium layer, this tissue plays a crucial role in the growth of the plant's vascular system.
3. Intercalary Meristem: Located at the base of leaves or internodes, this tissue helps in the growth of these plant parts.
Function of Meristematic Tissue
The primary function of meristematic tissue is cell division and growth. These tissues are responsible for producing new cells that differentiate into various specialized cell types in different parts of the plant. They are vital for the formation of new tissues and organs, allowing the plant to adapt to its environment and continue to grow.
In conclusion, meristematic tissue is crucial for plant growth and development as it produces undifferentiated cells that can differentiate into specialized cells needed for various plant functions. Understanding the role of meristematic tissue helps in comprehending the dynamic nature of plant growth and adaptation to environmental conditions.
