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

Consider the following two statements:

I. Cellular organization of the body is the defining feature of life forms.

II. Metabolic reactions cannot be demonstrated outside the body in cell-free systems.

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

The most obvious & complicated feature of all living organisms is:

(1) The ability to sense their surroundings or environment and respond to these environmental stimuli.

(2) Reproduction - sexual or asexual - for production of progeny of own kind.

(3) The ability to growth in size due to cell division.

(4) Presence of complex organs systems such as digestive and nervous system.

What is meant by the "species problem"?

(1) The exact definition of species is still controversial.

(2) The exact mechanisms of speciation is not known.

(3) The number of species present is much more than identified species.

(4) The extinction of species is taking place at an alarming rate.
