What does the chlorophyll in the chloroplast of a plant do? |
They absorb the Suns light energy |
|
|
What is the equation of photosynthesis? |
Carbon dioxide+ water --(+light energy)--> |
|
|
What is the first step of photosynthesis? |
Carbon dioxide is taken up by the leaves and water is taken up by the roots |
|
|
What is the second step of photosynthesis? |
The chlorophyll traps the light energy needed for photo synthesis |

The chlorophyll traps the light energy needed for photo synthesis |
|
|
What is the third step of photosynthesis? |
The energy is used to convert the carbon dioxide and water into glucose |

|
What does variegated leaf mean? |
Patches of green (with clorophyll) and patches of white (without clorophyll) |
|
|
How can we test leaves for starch? |
By using an iodine solution |
|
|
What colour will a vagriegated leaf turn? |
The green patches will turn blue-black to show starch has begun made |
|
|
What would happen to the rate of photosynthesis with a lack of light? |
It would slow doen |
|
|
What would happen to the rate of photosynthesis with a lack of light? |
It would slow doen |
|
|
What happens to the enzymes if it is cold? |
They will not work effectively which will slow down photosynthesis |
|
|
What happens to the rate of photosynthesis when there is too little carbon dioxide? |
The rate if photosynthesis will slow doenn |
|
|
What happens to the rate of photosynthesis when there is too little carbon dioxide? |
The rate if photosynthesis will slow doenn |
|
|
Where may carbon dioxide be limited? |
In an enclosed space eg in a greenhouse |

In an enclosed space eg in a greenhouse |
|
|
What is a limiting factor? |
Anything that puts a cap on the rate of photosynthesis |
|
|
What do you need to know during photosynthesis experiments? |
Which factor is being changed and which factors must be controlled |
|
|
What is the independent variable? |
The one being tested |
|
|
What is the dependent variable? |
The one you measure |
|
|
What may the glucose produced by photosynthesis be used for? |
It may be converted into insoluble starch for storage, are used for respiration, converted into fats and oil For storage, are used to produce cellulose, will strengthen cell walls, used to produce proteins |
|
