In the fridge
On their heads
Where do plants make their own food?
In the leaves
In the kitchen
At the bakery
In shop
What happens to plants at night?
They rest
They dance
They sing
They run around
Which plants grow very quickly towards the sun?
Beans
Stone
Shoes
Toys
Why do leaves turn yellow and red in autumn?
As chlorophyll disappears
Because they get more water
Because the sun shines brighter
Because there is more carbon dioxide
What is the Dutch name for photosynthesis?
Carbon assimilation
Plant breathing
Leaf growth
Light recording
What kind of organisms is algae?
Aquatic plants doing photosynthesis
Animals living in water
Stones that are green
Fish without fins
What's the best thing about photosynthesis?
That plants feed themselves and give us oxygen
That plants are green
That plants can grow big
That plants make flowers
Why are house plants important in the home?
They make the air cleaner by producing oxygen
They make the house warmer
They make noise
They give light
Why do plants struggle to grow in dark spaces?
They don't get enough light for photosynthesis
They have too much water
The air is too hot
There is too much oxygen
Where does the water that plants use usually come from?
From the soil via the roots
From the air via the leaves
From the sun via the stem
Out of the wind through the branches
Why are trees so big and strong?
Through years of photosynthesis, they make a lot of food
They eat other plants
They get food from animals
They grow without food
What happens to oxygen during photosynthesis?
It is made and released by the plant
It is absorbed by the plant from the air
It is converted into carbon dioxide
It is stored in the roots
What happens to excess glucose in plants?
It is converted into starch for storage
It will be discarded
It is used directly for growth
It is converted into water
Can plants perform photosynthesis in artificial light?
Yes, if the artificial light is strong enough
No, only in sunlight
Only with LED lamps
Only with incandescent lamps
What happens to photosynthesis at night?
Photosynthesis stops
Photosynthesis continues
Photosynthesis goes faster
Only oxygen is made
What happens when a plant gets too little carbon dioxide?
Photosynthesis slows down
Photosynthesis stops altogether
Plant makes more oxygen
The plant grows faster
Which season is best for the growth of most plants?
Spring and summer
Winter only
Autumn only
It does not matter
Which aquatic plants can photosynthesise underwater?
Seaweed and duckweed
Waterfront trees only
No aquatic plants
Flowers only
What makes leaves yellow and red in autumn?
The chlorophyll breaks down
More chlorophyll is added
Leaves make new dyes
Sunlight will be different
C4 plants have an advantage in high temperatures because they:
CO₂ concentrate around RuBisCO
Using less water for photosynthesis
Contain more chlorophyll
Growing faster in the shade
Stomatal conduction is mainly regulated by:
Locking cells
Epidermis cells
Mesophyll cells
Vascular bundles
Which factor most limits photosynthesis at low light intensity?
Light
CO₂ concentration
Temperature
Water
Which substance accumulates when the Calvin cycle is inhibited?
RuBP
3-phosphoglycerate
Glucose
Sucrose
Which substance activates RuBisCO in the morning?
Light-induced pH increase
High CO₂ concentration
Temperature rise
Water availability
Which enzyme catalyses the binding of CO₂ to RuBP in the Calvin cycle?
RuBisCO
PEP carboxylase
ATP synthase
NADPH reductase
What is the approximate pH of the thylakoid lumen during active photosynthesis?
pH 5
pH 7
pH 8
pH 9
Photorespiration uses how much ATP per fixed CO₂?
More than normal photosynthesis
Exactly the same
No ATP at all
Less than normal photosynthesis
What is the difference between cyclic and non-cyclic photophosphorylation?
Cyclic produces ATP only, non-cyclic produces ATP and NADPH
Cyclic uses both photosystems, non-cyclic uses one
Cyclic splits water, non-cyclic does not
Cyclic takes place in the dark, non-cyclic in the light
What happens to glucose after photosynthesis in plants?
It is converted into starch for storage
It is excreted immediately
It is converted into oxygen
It is used to make water
Which substance is used as a carbon source in photosynthesis?
Carbon dioxide
Carbon monoxide
Methane
Ethanol
What is the consequence of photorespiration?
Loss of fixed carbon and energy
Increased glucose production
Better water absorption
Faster growth
What is the function of the antennal complex in photosynthesis?
Collect and transmit light energy to reaction centres
Fixing CO2 into organic compounds
Producing ATP via chemiosmosis
Splitting water into oxygen
Which wavelength of light is least used for photosynthesis?
Green (500-600 nm)
Red (650-700 nm)
Blue (400-500 nm)
Violet (380-450 nm)
In which cells of C4 plants is CO2 concentrated?
Bundle sheath cells
Mesophyll cells
Epidermis cells
Shutter cells
What is the end product of the light reactions used in the Calvin cycle?
ATP and NADPH
Glucose and oxygen
ADP and NADP+
CO2 and H2O
