8
What are the raw materials needed for photosynthesis?
Light + Carbon Dioxide
Water + Glucose
Carbon Dioxide + Water
Oxygen + Chlorophyll
9
Which does not occur during photosynthesis?
Absorption of light by chlorophyll
Splitting of water molecules using light energy
Reduction of carbon dioxide to a carbohydrate
Conversion of glucose to sucrose
10
Which adaptation ensures a good supply of carbon dioxide to the cells inside the leaf?
Many chloroplasts inside palisade mesophyl cells
Xylem and phloem in veins
Thin cuticle on the lower epidermis
Large internal air spaces
11
True or false: Sucrose is changed into starch and stored in the leaves for future use?
False
True
12
Which mineral deficiency does this plant have?
Nitrate
Magnesium
Phosphate
Potassium
13
Why, when testing for starch, do we place the leaf in ethanol?
To soften it
So chlorophyll is extracted
To destroy membranes
To make it easy to spread out
14
How are magnesium ions used in plants?
Growth
Make chlorophyll
Plant stability
Make proteins from amino acids

What is the part labelled 5?
Vein
Xylem
Phloem
Stomata

Weak
Stunted
Chlorosis
Variegated
17
What is the term for: A leaf which has some parts that are white due to absence of chlorophyll?
Limited
Variegated
Chlorosis
De-starched
