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!
