Which structure is found in prokaryotic cells?
Nucleus
Mitochondrion
70S ribosome
Golgi apparatus
2.
Which statement best describes Eukaryotic cell?
A specialised structure within a cell with a particular function.
A double-membraned plant organelle containing thylakoids and stroma, the site of photosynthesis.
A system of membranes studded with ribosomes that makes and transports proteins.
A cell with a nucleus enclosed by a nuclear envelope and membrane-bound organelles.
3.
Prokaryotic cells differ from eukaryotic cells because prokaryotes
lack ribosomes
lack DNA
lack a cell membrane
lack a membrane-bound nucleus
4.

synthesise lipids only
store DNA
7.
An image is 30 mm; the object is 6 μm. The magnification is
×50
×500
×50 000
×5000
8.
Why can an electron microscope resolve more detail?
It uses coloured stains
Electrons have a shorter wavelength than light
Specimens are alive
It magnifies less

chitin
peptidoglycan
phospholipid
10.

11.
Which statement best describes Rough endoplasmic reticulum?
A specialised structure within a cell with a particular function.
The organelle containing chromosomes (DNA with histones), surrounded by a double membrane with pores.
A system of membranes studded with ribosomes that makes and transports proteins.
A double-membraned plant organelle containing thylakoids and stroma, the site of photosynthesis.
12.
Which statement best describes Mitochondrion?
A double-membraned organelle with folded cristae, the site of aerobic respiration and ATP production.
The organelle containing chromosomes (DNA with histones), surrounded by a double membrane with pores.
A small circular loop of DNA in prokaryotes, often carrying genes such as antibiotic resistance.
Stacks of flattened membrane sacs that modify, package and sort proteins and lipids into vesicles.
13.

Which of the following does not occur during RNA processing in the nucleus of eukaryotes?
The removal of introns from the RNA molecule
The addition of a string of adenine nucleotides to the 3 end
The addition of a guanine cap to the 5 end
The ligation of exons of the RNA molecule
The addition of methyl groups to certain nucleotides of the RNA molecules
