Question:
An isolated individual meristematic cell consists of the following cell wall layers
An isolated individual meristematic cell consists of the following cell wall layers
Show Hint
Meristematic cells are thin-walled, actively dividing cells with only a primary wall; secondary walls form in differentiated cells.
Updated On: Jun 19, 2026
- Middle lamellum and Primary wall
- Primary wall and Secondary wall
- Only Primary wall
- Middle lamellum, Primary and Secondary wall
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Characteristics of meristematic cells.
Meristematic cells are actively dividing, undifferentiated plant cells responsible for growth.
Step 2: Cell wall structure.
- Meristematic cells have only a primary wall that is thin and flexible.
- The primary wall is mainly composed of cellulose, hemicellulose, and pectin.
- Middle lamella is present between adjacent cells, not part of an individual isolated cell's wall.
- Secondary walls develop later in mature, differentiated cells for mechanical support.
Step 3: Conclusion.
Therefore, an isolated meristematic cell consists of only the primary wall.
Meristematic cells are actively dividing, undifferentiated plant cells responsible for growth.
Step 2: Cell wall structure.
- Meristematic cells have only a primary wall that is thin and flexible.
- The primary wall is mainly composed of cellulose, hemicellulose, and pectin.
- Middle lamella is present between adjacent cells, not part of an individual isolated cell's wall.
- Secondary walls develop later in mature, differentiated cells for mechanical support.
Step 3: Conclusion.
Therefore, an isolated meristematic cell consists of only the primary wall.
