Anthocyanins are water soluble pigments and appear red, purple depending on pH.
Mitochondria and choloroplast are :
I. semi-autonomous organelles.
II. formed by division of pre-existing organelles and they contain DNA but lack protein synthesizing machinery.
II is true but I is false
I is true but II is false
Both I and II are false
Both I and II are false
B.
I is true but II is false
Mitochondria and chloroplast have DNA and are capable of self-replication, thus they are semi-autonomous bodies
The organelles do synthesize some of protein and hence they have the protein synthesizing machinery. However, most of the proteins are derived from the nucleus.
