8D Quick quiz

1

Two kingdoms that contain many unicellular microorganisms are:

viruses and bacteria.

animals and plants.

yeast and fungi.

prokaryotes and prototists.

1

One feature of all prokaryotes is that they:

have chloroplasts.

do not have nuclei.

do not respire.

do not have cytoplasm.

1

Bacerial cells contain:

a strand of genes and a protein coat.

a cellulose wall

a strand of fats and a gene coat.

a peptidoglycan cell wall

1

Multicellular organisms need transport systems to carry materials to their cells because:

diffusion is not fast enough to do this.

diffraction is not fast enough to do this.

dissolving is not fast enough to do this.

dispersion is not fast enough to do this.

1

Which of these is a food often made using yeast?

chips

cheese

bread

yoghurt

1

Which of these shows the correct word equation for anaerobic respiration in yeast?

oxygen + glucose → carbon dioxide + water

carbon dioxide + water → oxygen + glucose

glucose → carbon dioxide + ethanol

glucose + carbon dioxide → oxygen + water

1

Three resources needed by all bacteria for growth are:

warmth, food and moisture.

light, carbon dioxide and glucose.

oxygen, nitrogen and mould.

darkness, moisture and nitrogen.

1

A product of fermentation of milk by bacteria is:

ethanol.

oxygen.

glucose.

lactic acid.

1

The drawing shows a bacterium.
What is the part labelled X called?

tail

chromosome

cilium

flagellum

1

Yeast reproduce by:

binary fission

binary fusion

fermentation

budding

1

The graph shows the growth of a population of yeast.
At point P the graph becomes level. One reason for this might be that:

the yeast cells can only grow to a certain size.

the food for the yeast has started to run out.

it has got dark and there is not enough light for the yeast to grow.

the carbon dioxide for the yeast has started to run out.

1

What process is shown in the diagram?

globulisation

globalisation

binary fission

glandibular separatisation

1

Three resources needed by algae are:

carbon dioxide, darkness, food.

water, warmth, light.

nitrogen, salt, water.

oxygen, glucose, darkness.

1

In total, the organisms that contain the most energy in a food web are the:

producers.

secondary consumers.

primary consumers.

top predators.

1

The drawing shows an Amoeba.
What does it use the parts labelled Y for?

photosynthesis

moving substances in and out of the cell

controlling the cell

storage

1

Why is light important for photosynthesis?

It transfers energy from the Sun.

It lets the organisms see.

It warms up the ground.

It contains chlorophyll.

1

A decomposer is:

an organism that spends a lot of its time asleep.

an organism that is used to remove poisons from contaminated soils.

an organism that breaks down dead organisms and animal wastes.

an organism that has ten legs.

1

Examples of organic compounds include:

sodium chloride, magnesium oxide and ammonium nitrate.

fish, meat and eggs.

water, oxygen and carbon dioxide.

glucose, proteins and fats.

1

Decomposers are important because they:

allow recycling of compounds

do not produce very much carbon dioxide.

can move very fast and escape from predators.

produce oxygen.

1

Which pair of processes both release the same products?

fermentation and photosynthesis

photosynthesis and aerobic respiration

photosynthesis and combustion

aerobic respiration and combustion

4
