What are the products of photosynthesis?
Carbon dioxide and water
Glucose and oxygen
Starch and carbon dioxide
Oxygen and water
22.
Why is ethanol used when testing a leaf for starch?
To kill the cells
To soften the leaf
To remove chlorophyll
To stain starch
23.
In bright light, hydrogencarbonate indicator around pondweed turns:
Yellow
Red
Orange
Purple
24.
A graph of rate against light intensity levels off. The best explanation is:
Chlorophyll is destroyed
Another factor, such as CO2, is now limiting
The plant is dead
Light is no longer absorbed
25.
Which statement best describes Variegated leaf?
Keeping a plant in darkness for about 48 hours so it uses up its starch stores before an experiment.
A green pigment in chloroplasts that transfers light energy into chemical energy for the synthesis of carbohydrates.
A leaf with green areas containing chlorophyll and white areas lacking it.
The process by which plants synthesise carbohydrates from raw materials using energy from light.
26.
Which statement best describes Chlorophyll?
A green pigment in chloroplasts that transfers light energy into chemical energy for the synthesis of carbohydrates.
A soluble sugar in which carbohydrate is transported through the phloem.
A leaf with green areas containing chlorophyll and white areas lacking it.
The process by which plants synthesise carbohydrates from raw materials using energy from light.
27.
Which statement best describes Hydrogencarbonate indicator?
The process by which plants synthesise carbohydrates from raw materials using energy from light.
Something present in the environment in such short supply that it restricts life processes.
An insoluble carbohydrate used by plants to store energy.
An indicator whose colour shows CO2 concentration: yellow (high), orange/red (atmospheric), purple (low).
