Start Quiz
1.
Which structure is found in prokaryotes but not eukaryotes?
80S ribosomes
Peptidoglycan cell wall
Mitochondria
Nuclear envelope
2.
An image is 5 mm; actual size is 50 µm. The magnification is:
×10
×1000
×100
×0.1
3.
Which organelle modifies and packages proteins?
Golgi apparatus
Lysosome
SER
Nucleolus
4.
Why does TEM give better resolution than a light microscope?
It uses stained specimens
Specimens are alive
Electrons have a shorter wavelength
It gives 3D images
5.
A group of similar cells performing a function is:
An organ
A system
An organelle
A tissue
6.
Who contributed 'all cells come from pre-existing cells'?
Hooke
Mendel
Darwin
Virchow
7.
Which statement best describes Cell theory?
The ability to distinguish two points that are close together as separate.
A small circular loop of DNA found in many prokaryotes, separate from the main chromosome.
The principle that all living things are made of cells, cells are the basic unit of life, and new cells come from pre-existing cells.
How many times larger an image is than the real object.
8.
Which statement best describes Prokaryotic cell?
A cell lacking a nucleus and membrane-bound organelles, with circular DNA in the cytoplasm.
A membrane system with ribosomes on its surface that synthesises and transports proteins.
Stacks of flattened membrane sacs that modify, package and sort proteins into vesicles.
The ability to distinguish two points that are close together as separate.
9.
Which statement best describes Resolution?
The ability to distinguish two points that are close together as separate.
A group of similar cells working together to perform a specific function.
A small circular loop of DNA found in many prokaryotes, separate from the main chromosome.
A cell with a nucleus and membrane-bound organelles.
10.
Which statement best describes Golgi apparatus?
A group of similar cells working together to perform a specific function.
A specialised structure within a cell that carries out a particular function.
A cell with a nucleus and membrane-bound organelles.
Stacks of flattened membrane sacs that modify, package and sort proteins into vesicles.
11.
The chart shows sizes. Which structures cannot be resolved with a light microscope (limit about 0.2 µm)?
Dr Dabour Hub Academy - figure 1
Bacterium and animal cell
Ribosome and virus
Plant cell only
All of them can be resolved
12.
A student compares onion epidermis and elodea leaf cells under a microscope. Which structure will only be seen in elodea?

Nucleus
Ribosome
Chloroplast
Cell wall
14.

The resolution of a light microscope is approximately

200 nm
0.5 nm
2 nm
20 μm
