Question

Chloride cells in Fresh water fishes.

• A. Secretes salts
• B. Absorbs salts
• C. Neither secretes nor absorbs salts
• D. Absorbs and secretes salts

Answer 1

Answer: (B)

Absorbs salts

Chloride cells are cells in the gills of teleost fishes which pump excessive sodium and chloride ions out into the sea against a concentration gradient in marine fish. Alternatively, in the gills of freshwater teleost fish, they pump sodium and chloride ions into the fish, also against a concentration gradient.

So, the correct option is 'Absorbs salts'.
