In the following questions, a statement of assertion (A) is followed by a statement of

reason (R). Mark the correct choice as:

(a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of

place the path of the beam becomes visible.

Reason: Light gets scattered by the colloidal particles.

12. Assertion: The endoplasmic reticulum which lacks ribosome is called smooth

endoplasmic reticulum (SER).

Reason: SER is mainly involved in protein synthesis.​

Answer 1

Answer:

11. Assertion is false and the reason is true,also the reason is correct explaination of assertion.

When a beam of light is passed through a colloidal solution placed in dark place the path of the beam is invisible bcz light gets scattered by the particles of colloidal solution.

12. Assertion is true but reason is false.

The SER lacks ribosome so they do not synthesis protein, they synthesis lipids.
