Study Notes

Meristematic Cells in Plants

Plastids in meristematic cells are small, undifferentiated, and lack pigments, allowing them to differentiate into various types of plastids later in development.
Meristematic cells are responsible for plant growth and development, producing new tissues and organs through cell division and differentiation.
The main characteristic of meristematic cells is their ability to divide and differentiate into various cell types, making them capable of continuous growth and development.

Structure and Organization

Meristematic cells are packed closely together without intercellular spaces, allowing for efficient cell-to-cell communication and coordination of growth and development.
