Assertion (A): Some bacteria can synthesize their own food.
Reason (R): These bacteria have green matter called chloroplasts.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Incorrect AnswerBoth (A) and (R) are true but (R) is not the correct explanation of (A).
Incorrect Answer(A) is true but (R) is false.
Correct Answer(A) is false but (R) is true.
Incorrect AnswerExplanation:
Bacteria are a type of biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust. Some bacteria can synthesize their own food due to presence of chlorophyll. Unlike in multicellular organisms, increases in cell size (cell growth) and reproduction by cell division are tightly linked in unicellular organisms. Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction.
