Total questions: 20
Worksheet time: 10mins
Which statement was NOT included in cell theory?
All living things are composed of cells.
Living cells come only from other living cells.
Each cell contains a cell membrane, cytoplasm, nucleus, mitochondria, and endoplasmic reticulum.
Cells are the smallest structure of living things that can perform the functions necessary for life.
A plant cell is
Eukaryotic
Prokaryotic
I am a single-stranded RNA molecule. I don't have information to code for any protein, hence I am naked. Yet, I am a pathogen can I can replicate using host transcription machinery. Who am I?
Virion
Virus
Viroids
Virusoids
Prions
Virusoids are
pathogenic DNA
pathogenic RNA
satellite subviral particle that needs the help of Helper viruses
autonomously replicating subviral particle
synthesis proteins
Virion is
a subviral RNA particle molecule that can replicate themselves
a subviral RNA particle molecule that cannot replicate themselves
inactivate viral particle
the infectious extracellular phase of virus
the infectious intracellular phase of virus

A- Pilus, B- Plasmid, C- Nucleiod, D- Flagella, E-Cell wall, F- Plasma membrane, G- Fimbriae
The outer layer which is made up of proteins and carbohydrates in a cell which helps in cell adhesion is called
Cell Wall
Capsule
slime layer
Glycocalyx
Axial Filaments
are seen in Spirochaetes
are exoflagella,
are endoflagella
are structures that help in attachment
Fimbriae are
are short fibres on the surface of some bacteria. Seen on both gram-positive and gram-negative bacteria.
Made up of fibrillin protein. Shorter than pili and flagella
Evenly distributed throughout the cell surface
The main function is surface attachment.
The independently replicating extra-chromosomal DNA in bacteria that transmit genes encoding drug resistance, bacteriocins, toxins is called
Mesosome
Plasmid
Nucleoid
Episome
PPLO
is also called Prions
is also called Mycoplasma
Mycoplasma
lacks cell wall
can attain different shapes
smallest bacteria
commensal bacteria found widely in association with mucous membranes of all mammalian species.
also called pleuro pneumonia like organism
Naked Viruses
Lacks Capsid
has capsid
Lacks envelope
has envelope
Vesicular membrane structures are formed by an invagination of the plasma membrane in prokaryotes which are more prominent in Gram-positive organisms.
Mesosomes
Plasmids
Episomes
