Middle lamella is composed mainly of
A
Phosphoglycerides
B
Hemicellulose
C
Muramic acid
D
Calcium pectate
Detailed Solution
The middle lamella is the layer that holds or glues the neighbouring plant cells together.
It is formed first, at the cell plate, during cytokinesis, and it is made mainly of calcium pectate.
Hemicellulose is a component of the primary and secondary cell walls, phosphoglycerides are membrane lipids, and muramic acid is a component of the bacterial cell wall (peptidoglycan).
Hence the middle lamella is composed mainly of calcium pectate.
