Cell Biology: SQA National 5 Biology Area 1 quiz quiz

Cell membrane, cytoplasm and ribosomes

Cell wall, chloroplasts and vacuole

Nucleus, mitochondria and plasmids

Chloroplasts, plasmids and chitin

A plasmid (a small ring of DNA)

A true nucleus

A cellulose cell wall

A chloroplast

It allows some molecules to pass more easily than others

It allows all molecules to pass freely

It blocks every molecule from entering

It only allows water to pass

From a higher to a lower concentration, needing no energy

From a lower to a higher concentration, needing energy

Of water only, through a selectively permeable membrane

Against the concentration gradient using ATP

Water enters by osmosis and the cell may swell and burst

Water leaves by osmosis and the cell shrinks

The cell becomes turgid but does not burst

There is no net movement of water

It moves molecules against the gradient and needs energy from respiration

It moves molecules down the gradient and needs no energy

It moves only water molecules

It happens only in bacterial cells

Thymine

Cytosine

Guanine

Uracil

To carry a complementary copy of the code from the nucleus to the ribosome

To break down glucose in the mitochondria

To form the cell wall of plant cells

To pump ions across the membrane

Its active site has a shape complementary to that substrate

It is used up after one reaction

It works at any temperature and pH

It is made of glucose

Its active site changes shape and it is denatured

It works faster and faster with no limit

It turns into a substrate

It becomes a hormone

A plasmid

A ribosome

A chromosome

A mitochondrion

Cut out gene, open plasmid, insert gene, return plasmid, grow bacteria

Grow bacteria, cut out gene, open plasmid, insert gene, return plasmid

Open plasmid, grow bacteria, insert gene, cut out gene, return plasmid

Insert gene, cut out gene, grow bacteria, open plasmid, return plasmid

glucose + oxygen produces carbon dioxide + water + energy

carbon dioxide + water produces glucose + oxygen

glucose produces lactate + energy

glucose produces ethanol + carbon dioxide + energy

In the cytoplasm

In the mitochondria

In the nucleus

In the ribosome

Ethanol and carbon dioxide

Lactate only

Glucose and oxygen

Water and carbon dioxide

To transfer energy for processes such as muscle contraction and cell division

To store the genetic code

To form the cell membrane

To carry oxygen in the blood
