Study Notes
Differentiation of Cells
- Meristematic tissue produces cells that are undifferentiated.
- Differentiation is the process where these cells take on a permanent role, size, and shape.
- This process is crucial for developing specialized tissues and organs in plants.
- Undifferentiated cells are typically small, with a thin cell wall, and active metabolism.
- Differentiated cells have distinct structures and functions tailored to their specific roles. Examples include xylem cells for water transport or phloem cells for nutrient transport.
- Specialized cells have a large vacuole.
- Specialized cells have thicker cell walls, which provides structure and support.
- The process of differentiation in plants is complex and regulated by various factors, including environmental cues and internal signals.
- Differentiation involves changes in gene expression, leading to the production of specific proteins that dictate cell structure and function.
- Differentiated cells are often tightly connected or organized to form functional tissues, such as the epidermis, vascular tissues (xylem and phloem), or supporting tissues.
- The process of cell differentiation is irreversible.
- Differentiation is not uniform across the entire tissue. Different specialized cells form distinct regions within a developing tissue.
- Factors influencing differentiation include light exposure, nutritional availability, and environmental stress.
- Once a cell differentiates it typically does not undergo further division.
- Differentiation involves modifications in cellular structure and function to suit the specialized task.
