Choose incorrect statement regarding cells

Which of the following cell organelle is closely associated with ER & helps in formation of plasma membrane during cytokinesis?

1.  Centrosome

2.  Sphaerosomes

3.  Golgi bodies

4.  Ribosomes 

The ability of proteins to move laterally within the overall bilayer lipid molecules of plasma membrane is measured as its

1.  Stability

2.  Thickness

3.  Degree of permeability

4.  Fluidity 

Neutral solutes directly pass through the lipid bilayer of plasma membrane because

1. Plasma membrane has special carrier for them

2. They are lipid soluble

3. They have specific hydrophilic areas for their passage

4. They consume ATP 

Find the incorrect statement

1.  Middle lamella is mainly made up of calcium and magnesium pectate

2.  Cell wall is formed on the inner side of the cell therefore secondary wall formed first

3.  Middle lamella glues the neighbouring cells together

4.  Cell wall helps in cell to cell interaction and provides barrier to undesirable macromolecules
