Differentiate between the following pairs of terms based on the clues given in parentheses: (i) Cell membrane and cell wall (permeability) (ii) RER and SER (structure) (iii) Chloroplasts and chromoplasts (pigments)

Answer
Each pair differs in permeability, structure or pigment.

Explanation

Pair (clue) First term Second term
Membrane vs wall (permeability) Selectively permeable. Permeable (lets water and minerals through).
RER vs SER (structure) Has ribosomes on its surface. No ribosomes; looks smooth.
Chloroplast vs chromoplast (pigments) Green pigment (chlorophyll). Yellow, orange or red pigments.
Permeability, ribosomes and pigments are the key differences.
