Name three substances that can diffuse through cell membranes?
Oxygen, Amino acids, Glucose, Water.
6 of 24
Name two substances that can't diffuse through cell membranes?
Starch, Proteins.

What is the equation for photosynthesis?
Carbon dioxide + water. -->. Glucose + Oxygen
16 of 24
What is the green substance in leaves that absorbs sunlight?
Chlorophyll.
17 of 24
Name the three factors that can limit photosynthesis.
Light, Temperature, Carbon dioxide.
18 of 24
Explain why it is important that aplant doesn't get too hot.
If the plant gets too hot, the enzymes it needs for photosynthesis and its other reactions willbe damaged.

Describe three thongs a gardener could do to make sure they grow a good crop of tomatoes in their greenhouse.
At winter, use a heater so the plants can still photosynthise. Use artifical light at night so plants can still photosynthise. Add fertilisers to the soil to provide the minerals plants need for a healthy growth.

Why is glucose turned into starch when plants need to store it for later?
Starch is insoluble which makes it better for storing then glucose.
21 of 24
What are the five ways that plants can use the glucose produced by photosynthesis
For respiration, Making cell walls, Making proteins, Stored in seed, Stored as starch.
22 of 24
What is a habitat?
A habitat is aplace where an organism lives.
23 of 24
What are five ways that can affect the distribution of organisms?
Temperature, Availability of water, Availability of oxygen and carbon dioxide, Availability of nutrients, Amount of light.
