Living organisms exhibit distinctive characteristics to differentiate from non-living objects. Which one of the following statements can be considered as defining property of living things?
1 Increase in body mass as a criterion for growth
2 Reproduction is synonymous with growth in unicellular organisms
3 Ability of living organisms to sense their surroundings
4 Metabolic sections that can be demonstrated outside the body in cell-free system only
Biologists have established certain procedures and techniques to store and preserve the information as well as specimens. Amongst these which one has collection of both preserved plant and animal specimens?
1 Zoological parks
2 Herbarium
3 Museum
4 Botanical gardens
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 all inclusive defining characteristic of living organisms
3 Living organisms are self replicating, self regulating and evolving interesting systems
4 isolated metabolic reactions in vitro are living things
Choose the wrong statements with respect to distinguishing characteristics of living beings
1 In majority of higher, 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
1 Growth cannot be taken as a defining property of living organisms
2 Growth can be easily observed in vitro culture
3 Metabolic reactions cannot be demonstrated outside the body in cell-free system
4 All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues
An attribute found in plants but not animals is
(1) Metabolism
(2) Sexual reproduction
(3) Autotrophy
(4) Asexual reproduction
Find out the wrong statement out-
1. | Increase in mass and increase in number of individuals are twin characteristics of growth. |
2. | Growth, reproduction and ability to respond are the only unique features of living organisms. |
3. | a and b both |
4. | Metabolism, ability to self-replicate and self-organise are the unique features of living organisms. |
In------------- of higher animals and plants-------- and ------- are mutually------ events.
a. All, cell division, replacement, dependent
b. Majority , growth, reproduction, exclusive
c. All, growth, cell division, dependent
d. Majority ,cell division, replacement, exclusive
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.
c. Accumulation or increase in mass from inside is the basis of growth in living beings.
d. Growth is considered as defining property of living beings.
Growth is not considered as a defining property of living beings because
a. It is difficult to observe or measure.
b. Not a single criterion for the measurement of growth.
c. Also observed in non-living
d. Cannot be tracked as growth is from inside
