The cells are held together by a Ca-pectate layer are called as:
Correct answer: C. Middle lamella
- A. Primary cell wall
- B. Secondary cell wall
- C. Middle lamella
- D. Tertiary cell wall
Explanation
The plant cell is surrounded by cellulosic cell walls. The cell walls of two adjacent cells are separated by middle lamella which literally means middle plate or middle membrane. Middle lamella is actually the cementing layer between two plant cells. It is absent on the outer surface. It ruptures to create intercellular spaces wherever required. It is formed of calcium and magnesium pectate.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
