Question

Consider the following statements and state true(T) or false(F).
a) Dictyosomes are simpler units of golgi apparatus in animal cells.
b) Teichoic acid is absent in cell wall of gram negative bacteria.
c) Viruses are an exception to cell theory.

• A. a(T), b(F), c(F)
• B. a(T), b(T), c(F)
• C. a(F), b(T), c(T)
• D. a(F), b(F), c(T)

Answer 1

The correct option is C a(F), b(T), c(T)

Dictyosomes are a stack of cisternae which form Golgi bodies and are present in plants. Therefore statement "a" is False.

Teichoic acids are covalently linked to peptidoglycan layers of Gram-positive bacteria and are absent in gram-negative bacteria and therefore, the statement "b" is True.

Cell theory states that all living cells are made of cells which act as a fundamental unit but viruses depend on host systems to replicate their DNA or RNA and hence they are not made of true cells but still considered as living organisms. therefore they are an exception for Cell theory. Therefore the statement "c" is True.

Therefore the right option is option C, a(F), b(T), c(T).
