Starter What do I need to live a healthy life?
Learning Outcomes
Photosynthesis
ALL Write out the equation for photosynthesis
MOST Describe how the leaf is designed for photosynthesis
SOME Explain why photosynthesis is needed
Summarise the animationFill in the word gaps on page 1
Photosynthesis
Chloroplasts
Filled with a green pigment called Chlorophyll
Carbon dioxide + Water Glucose + Oxygen
Sunlight
Chlorophyll
Study the diagram on page 2 and
answer the questions
Leaf Structure
Activity - Bioviewers
Using the bioviewer, choose 3 different
types of plant cell to draw.
For each cell type
1. Describe the cells function (job)
2. Describe any adaptations it has to perform this job
Complete the questions on page 3 & 4 using the diagram and the knowledge you have gained.
Use the text book to help if needed.
CARD SORT ACTIVITY
Sort the cards to match the diagram.
Once you have sorted the cards ask the teacher to check they are correct before writing on your
worksheet.
How would we measure how fast photosynthesis
happens?
sunlight
Light level
(in lux)
Number of
bubbles in 1
minute
123456
Rate of photosynthesisPlants make oxygen
when they photosynthesis…
An experiment was carried out to see how different light intensities effected the rate
of photosynthesis
On a sunny day there is more light!
… we can measure how much oxygen is made in
one minute
The more oxygen is made the faster
photosynthesis MUST be happening!
