Question

Assertion (A) In tissue culture, whole plant can be produced from any plant cell.
Reason (R) Plant cells possess totipotency which allow any viable plant cell to differentiate into somatic embryo that can give rise to different cells of plants.

• A. If both A and R are true and R is the correct explanation of A
• B. It both A and R are true, but R is not the correct explanation of A
• C. If A is true, but R is false
• D. If A is false, but R is true

Answer 1

Answer: (A)

Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
In tissue culture, somatic embryos or embryoids are non-zygotic embryo like structures that develop in vitro cultures from somatic cells of any type of tissue. Here ‘totipotency’ property of plants cells is used, which allow whole plant to be produced from any one plant cell.
