Consider the following two statements:

I. In the single-celled organisms, we are not very clear about the usage of the two terms – growth and reproduction.

II. When it comes to unicellular organisms like bacteria, unicellular algae or amoeba, reproduction is synonymous with growth, i.e., increase in number of cells.

1. Both I and II are true and II explains I

2. Both I and II are true but II does not explain I

3. I is true but II is false

4. Both I and II are false

Which one of the following is common to multicellular fungi, filamentous algae and protonema of mosses?

(1) Diplontic life cycle

(2) Members of kingdom-Plantae

(3) Mode of nutrition

(4) Multiplication by fragmentation

Which one of the following is common to multicellular fungi, filamentous algae and protonema of mosses?
1. Diplontic life cycle
2. Members of kingdom-Plantae
3. Mode of nutrition
4. Multiplication by fragmentation

Living organisms can be unexceptionally distinguished from non-living things on the basis of their ability for:

In how many organisms present below in the box in which reproduction is synonymous with growth?

Amoeba, Yeast, Diatom, Mules, Spirogyra, Mangifera, Panthera, Datura and Gonyaulax

1. 7
2. 5
3. 4
4. 6

What is incorrect statements-

1. Organisms that can respond to stimuli are with a well developed nervous system..

2. Generally growth and reproduction are mutually exclusive events in higher organism.

3. Mules and sterile worker bees do not reproduce.

4. Metabolic reactions may take place in isolated cell-free systems

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-
a. Increase in mass and increase in number of individuals are twin characteristics of growth.
b. Growth, reproduction and ability to respond are the only unique features of living organisms.
c. a and b both
d. Metabolism, ability to self-replicate and self-organise are the unique features of living organisms.

d. (p-2); (q-2); (r-3); (s-3); (t-1); (u-1)

Increase in number can be-
a. Growth
b. Reproduction
c. Both a and b
d. Accumulation
