5 Questions
What is the role of plastids in meristematic cells?
They are undifferentiated, but present in rudimentary form (proplastids)
What is the function of meristematic cells in plants?
They provide new cells for expansion and differentiation of tissues
What is the main characteristic of meristematic cells?
They are totipotent and capable of continued cell division
Why are meristematic cells packed closely together without intercellular spaces?
To support rapid cell division and expansion of tissues

Carl Wilhelm von Nägeli
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.
History of the Term 'Meristem'
- The term 'meristem' was first used by Carl Wilhelm von Nägeli in 1858 to describe the undifferentiated cells responsible for plant growth.
