Cell is the fundamental structural and functional unit of all living organisms. This statement can be best justified by the fact that:

1.	The cells contain nucleic acids that contain genetic information
2.	A large number of organelles present in the cell perform various functions
3.	Anything less than a complete structure of a cell does not ensure independent living
4.	All multi-cellular organisms begin their life as a single celled zygote

Who first saw and described a living cell?

Who concluded, based on his studies on plant tissues, that the presence of cell wall is a unique character of plant cells?

The famous aphorism ‘omniscellula-e-cellula’ was added to the cell theory in 1855 by

Ribosomes are non-membrane bound organelles found in:
1. All prokaryotic cells only
2. All eukaryotic cells only
3. All somatic cells in eukaryotic organisms only
4. All cells

A non-membrane bound organelle found in animal cells that helps in cell division would be:

A ‘comma’ shaped bacterium is known as a:

1. Bacillus
2. Coccus
3. Vibrios
4. Spirillum

The genomic DNA of a bacterial cell is:

1. circular and located on a single chromosome
2. circular and located on multiple chromosomes
3. linear and located on a single chromosome
4. linear and located on multiple chromosomes

Extra-chromosomal circular double stranded and autonomously replicating DNA found in many bacteria is known as:

A ‘slime layer’ or a ‘capsule’ is a modification of which of the following layers of the cell envelope of a prokaryotic cell?
