Q

Explain 3 things about chloroplasts and chlorophyll…

A

Chloroplasts have bubbles or chlorophyll.

Chlorophyll is a green pigmented chemical, it can absorb sunlight (it makes plants green).

17
Q

What do all living things need?

A

Energy

18
Q

What are plants are called?

A

Producers

19
Q

What is the name of the waste gas is produced during photosynthesis?

A

Oxygen

20
Q

How can the rate of photosynthesis be measured?

A

Because oxygen waste product was released from plants while photosynthesising,count the rate of bubbles from pondweed.

21
Q

What happens as the light source moves further away from the pond weed?

A

The number of bubbles per min decrease as the light source moves further away.This is because plants needed light to photosynthesise.
