Q. No.Mark the correct statements with respect to living organisms
1. Growth and cellular organisation are considered as defining properties of living organisms
2. Reproduction can be an all-inclusive defining characteristic of living organisms
3. Living organisms are self replicating, self regulating and evolving interactive systems
4. Isolated metabolic reactions in vitro are living things
Choose the wrong statement with respect to distinguishing characteristics of living beings
| 1. | In majority of higher category/organisms, the growth and reproduction are mutually exclusive events |
| 2. | Degrowth will occur when catabolism exceeds anabolism |
| 3. | Isolated metabolic relations in-vitro are neither living things nor living reactions |
| 4. | Growth cannot be taken as a defining property of living organisms if we take increase in body mass as a criterion on growth |
Select incorrect statements with respect to living beings

What is correct with respect to Growth?
a. Increase in body mass is not a criterion for growth.
b. Increase in body mass is not observed in non-living things.
