Tag the questions with any skills you have. Your dashboard will track each student's mastery of each skill.
The process of photosynthesis takes in energy from the surroundings (in the form of light energy).
Is this type of reaction endothermic or exothermic?
What is the limiting factor at 'point b' on the graph?
What is the limiting factor at 'point a' on the graph?
Which tissue transports water to the leaves?
How do plants obtain the CO2 needed for photosynthesis?
What is the name for the loss of water from the leaf by evaporation?
Name the gas released as bubbles from an aquatic plant that is photosynthesising
What is the name for the movement of water through the plant (from root to leaf)
In an experiment to see the effect of light intensity on the rate of photosynthesis, what is the Independent Variable?
In an experiment to see the effect of light intensity on the rate of photosynthesis, what is the Dependent Variable?
In an experiment to see the effect of light intensity on the rate of photosynthesis, which factors are Control Variables?
Plants make glucose during photosynthesis. Some of the glucose is changed into insoluble starch. What happens to this starch?
What happens to the light intensity (and therefore the rate of photosynthesis) if the distance between the lamp and the plant is doubled?
A plant is growing 50cm from a light source. The light intensity at the plants leaves is 10 arbitrary units.
If the plant is moved to a distance 100cm the new light intensity will be ...
Some plants can be grown with their roots in water instead of soil.
Why is this useful in agriculture?
Plants need to take in nitrates from the soil in order to make amino acids (the plant also needs glucose made during photosynthesis for this)
Plants use some of the glucose they make to build new cell walls.
What are plant cell walls made of? (name the carbohydrate)
Plants need to take in nitrates from the soil in order to make amino acids (the plant also needs glucose made during photosynthesis for this).
Which type of biological molecule is made from long chains of amino acids
Some of the glucose plants make during photosynthesis is used for respiration.
What is respiration?
Some of the glucose plants make during photosynthesis is used to make lipids (fats and oils).
What are lipids made from (building blocks)?
Plants make glucose during photosynthesis. Some of the glucose is changed into insoluble starch.
What is the test for starch?
The picture shows an experiment to see the effect of light intensity on the rate of photosynthesis by counting the number of bubbles released in 1 minute.
Why is this not an accurate way of measuring the rate of photosynthesis?
The picture shows an experiment to see the effect of light intensity on the rate of photosynthesis by counting the number of bubbles released in 1 minute.
How could the rate of photosynthesis be measured more accurately?
The picture shows an experiment to see the effect of light intensity on the rate of photosynthesis by counting the number of bubbles released in 1 minute.
Name the gas released in the bubbles
The picture shows an experiment to see the effect of light intensity on the rate of photosynthesis by counting the number of bubbles released in 1 minute.
How could the student control the temperature?
