1

In a photosynthesis experiment, a plant is left in bright sunlight for several hours. A leaf is then removed from the plant and tested for starch, using iodine solution.

The diagram shows the leaf from the plant that was used in the experiment.

Which diagram shows the result of the experiment

1

Which substance, needed for protein synthesis, is carried into a leaf from the stem?

1

Which two substances are the products of photosynthesis?

1

Four test-tubes are set up as shown in the diagram and left in full sunlight.
After several hours, which test-tube contains the most dissolved oxygen?

1

Plants manufacture their own supplies of carbohydrate.
What are the raw materials and the waste product of this process?

1

A plant with variegated leaves has the starch removed from its leaves by placing it in a dark cupboard for 48 hours. Black paper is then fixed on one leaf as shown and the plant is exposed to light.

After 24 hours, which part of the leaf contains starch?

1

A plant with striped leaves similar to the one below was kept in bright light for six hours.
A leaf was taken from the plant and the chlorophyll removed. It was then tested for starch using iodine solution.
Which diagram shows the result of the test?

1

This apparatus was set up as shown.
Sodium hydroxide removes carbon dioxide from the air. Limewater goes cloudy if carbon dioxide is bubbled through it.
What happens to the limewater in flasks X and Y when the pump is switched on?

1

An experiment was done using the apparatus shown in the diagram.
The carbon dioxide content of the water in each tube was measured at the start and again three hours later.
In which tube would there be a decrease in carbon dioxide content?

1

What is formed first in a leaf as a result of photosynthesis?

1

From which part of a leaf does most water evaporate during transpiration?

1

Which product of photosynthesis moves out of a green leaf through its stomata?

1

Which two substances are needed for photosynthesis?

1

Which process does not release water?

1

The diagram shows a palisade cell.
In which region is starch stored?

1

The diagram shows the apparatus used in an investigation to measure the rate of oxygen production during photosynthesis.
The investigation was repeated several times and the average amount of gas collected was calculated.

Which two factors must be kept constant during this investigation?
