Write the word equation for photosynthesis.

Write the balanced symbol equation for photosynthesis.

Why are light and chlorophyll needed for photosynthesis?

Describe why photosynthesis is an endothermic reaction.

When and why do plants respire? Explain the relationship between photosynthesis and respiration in leaves.

State the 3 limiting factors for photosynthesis.

What other factors might limit the rate of photosynthesis between B and C.

What are the benefits and drawbacks of changing conditions inside a greenhouse?

Label the structure of the leaf. Explain how stomata open and close. Explain how the adaptations of the palisade mesophyll allow it to photosynthesise efficiently.

Define diffusion. Describe how we can increase the rate of diffusion.

Explain how materials pass in and out of cells. Use a diagram to help you.

What effect do you think increasing the concentration gradient will have on the speed of diffusion?

a. if you are investigating the effect of light intensity on the rate of photosynthesis what other variables must you control?b. draw a diagram to show how could measure the effect of light intensity on photosynthesis sing equipment you would find in a school laboratory. Show how you would set up the equipment and label each part.

Will diffusion ever stop completely? Explain your answer.

What is transpiration? Compare and contrast phloem and xylem.

Explain how the structure of a leaf is adapted to reduce water loss.

Describe an experiment to show that traspiration rate is affected by air movement.

Name 4 conditions that affect the rate of water movement in plants and explain the impact of one of them.

Predicit and draw graphs to describe and explain how trnspiration rate is affected by:a. cold condictionsb windy conditions.c. dull cloudy conditionsd. still, humid conditions.

What is translocation? List the ways plants use the products of photosynthesis.

Explain how the phloem cells are adapted to support their function.
