The first layer of cell wall which is formed is called?
Correct answer: C. Middle Lamella
- A. Primary Wall
- B. Secondary Wall
- C. Middle Lamella
- D. All of the above
Explanation
The correct answer is Middle Lamella. It is the first layer to form during cell wall development, serving as a pectin-rich adhesive between plant cells. The Primary Wall follows the middle lamella, facilitating cell growth and flexibility. The Secondary Wall develops after the primary wall, providing additional support and rigidity. Therefore, options A and B are incorrect as they pertain to layers formed after the middle lamella. Option D is also incorrect since not all listed layers are the first to form.
