1. | Both (A) and (R) are True and (R) correctly explains (A) |
2. | Both (A) and (R) are True but (R) does not correctly explain (A) |
3. | (A) is True but (R) is False |
4. | (A) is False but (R) is True |
A: | The eukaryotes include only multicellular organims. |
B: | Animal cells have centrioles which are absent in almost all plant cells; Spindle formation is seen in animal seen which is absent in all plant cells. |
C: | The isolated lysosomal vesicles have been found to be very rich in almost all types of oxidative enzymes. |
D: | Like chloroplasts, the mitochondria are also double membrane bound and easily observed under the microscope as they are large. |
E: | In case of acrocentric chromosome the centromere is situated close to its end forming one extremely short and one very long arm, whereas the telocentric chromosome has a terminal centromere. |
