C
A
B
D
3
Which of the following are the correct reactants for the process of photosynthesis?
Carbon dioxide + Glucose
Water + Glucose
Water + Carbon dioxide
Glucose + Oxygen
4
The leaf is a plant organ. Which of the tissues below are NOT present within a leaf?
Palisade mesophyll tissue
Meristem tissue
Epidermal tissue
Xylem and phloem tissue
5
How are xylem cells adapted for their function?
thick cell walls and with holes in them to form sieve plates
The cells are dead and hollow
contain no lignin to make them fully permeable to water
hairs to increase their surface area for water absorption
6
What is the name of the structures labelled C?
Guard cells
Stomata
Air space
Lower epidermis
7
What is the rate of transpiration for cool moving air to 2 significant figures?
90 mm/s
0.67 mm/s
40 mm/s
0.025 mm/s
8
Photosynthesis is a type of...
Endothermic reaction
Exothermic reaction
9
If the temperature is decreased the rate of photosynthesis will
stay the same
increase
decrease
10
How could the student measure the rate of photosynthesis more accurately?
Measure the change in mass of the pondweed in 30 seconds
Count the number of bubbles produced in 1 minute
Place the pondweed further from the light source
Use water instead of sodium hydrogencarbonate solution
11
Energy is absorbed by a green pigment called
chlorophyll
chloride
chloroplast
12
Which of these is NOT an adaptation of the leaves for efficient photosynthesis
Palisade mesophyll cells contain many chloroplasts
Leaves are broad and very thin
The upper epidermis is transparent
Stomata on the upper epidermis allow carbon dioxide to enter
13
Which graph below show a graph of transpiration rate against increasing light intensity
D
C
A
B
14
The energy needed for photosynthesis comes from
osmosis
respiration
light
15
What is the role of phloem?
Transports water from the roots to the leaves
Transports starch around the plant
Absorb sugar from the soil into the roots
Transports sugars around the plant
16
To test the presence of starch in a leaf, which of the following chemicals should be used?
Benedicts Solution
Ethanol
Biurets reagent
Iodine
17
Some of the food made by plants is stored as insoluble
starch
chlorophyll
glucose
18
What is transpiration?
The movements of sugars through plants through the phloem
Movement of water from roots to the leaves through the xylem
Evaporation of water from the leaves of a plant
Evaporation of water from the roots of a plant
19
At which light intensity was light a limiting factor for photosynthesis?
1 arbitrary unit
10 arbitrary unit
4 arbitrary unit
20
During translocation
Dissolved sugars move from leaves to the rest of the plant
Water and minerals move from roots to the rest of the plant
Water and minerals move from leaves to the rest of the plant
Dissolved sugars move from roots to the rest of the plant
