16
Q

What separating technique can be used to separate different pigments within a mixture?

A

Chromatography

17
Q

Why must the origin line be drawn in pencil?

A

To prevent it being carried up the paper

18
Q

What is the mobile phase?

A

The phase which moves - the solvent

19
Q

Name two examples of solvents

A

Water and an alcohol, e.g. ethanol

20
Q

What is the stationary phase?

A

The phase which does not move - the paper

21
Q

How do you calculate the Rf value of a pigment?

A

Distance moved by compound ÷ Distance moved by the solvent

22
Q

Where should the distance moved by the compound and solvent be measured from?

A

From the origin line

23
Q

What does it mean if a spot is left on the origin left after chromatogarphy is carried out?

A

The pigment is insoluble in the solvent

24
Q

State the reactants for photosynthesis

A

Carbon dioxide and water

25
Q

State the products of photosynthesis

A

Glucose and oxygen

26
Q

Where in the cell does photosynthesis occur?

A

Chloroplasts

27
Q

Which pigment in leaves absorbs the sunlight needed for photosynthesis?

A

Chlorophyll

28
Q

How do plants store glucose?

A

As starch

29
Q

State three factors which affect photosynthesis

A

Light intensity, temperature, carbon dioxide concentration

30
Q

What are stomata?

A

Holes in the leaf which allow gases to diffuse in and out of the leaf

31
Q

How are the stomata able to open and close?

A

Guard cells fill with water to open the stomata or close the stomata when water leaves the guard cells

32
Q

Name two plant diseases

A

Tobacco mosaic virus (TMV) and rose black spot

33
Q

Which type of pathogen causes TMV?

A

Virus

34
Q

Which type of pathogen causes rose black spot?

A

Fungus

35
Q

How is rose black spot spread between plants?

A

Fungal spores

36
Q

How can the spread of rose black spot be prevented?

A

Watering the plants at the base, not on the leaves; planting roses far apart to allow air movement; clearing up old leaves that have fallen off the plants; fungicides

37
Q

How can the spread of TMV be prevented?

A

Washing gardening tools and hands after touching infected plants; not using infected soil for 2 years

38
Q

Name the process by which water evaporates through stomata in the leaves.

A

transpiration

39
Q

What two products are produced when carbon dioxide and water combine in photosynthesis?

A

Glucose and oxygen
