Question

Pectic polysaccharides are present in

• A. Cytoskeleton
• B. Plasma membrane
• C. Primary cell wall
• D. Tertiary cell wall

Answer 1

The correct option is C Primary cell wall

• A cell wall is a tough and flexible structural layer that surrounds cell membrane in plants, algae and most prokaryotes.
  
• It consists of the following three layers- 1) primary cell wall, 2) secondary cell wall and 3) middle lamella.
• The primary cell wall is the first outermost thin, flexible and extensible layer.
• It is made up of the cellulose, hemicelluloses and pectin (polysaccharides).
• So, the correct answer is 'Primary cell wall'.
