25
What factors affect the distribution of plants?5
``` Light intensity Water availability Temperature Nutrients Oxygen and carbon dioxide ```
26
How does water availability affect the distribution of animals and plants?
- low rainfall means it's difficult for photosynthesis to occur
27
How does a lack of light intensity affect the distribution of organisms?
Plants are less likely to grow because their ability to photosynthesise is impaired
28
How does a lack of temperature affect the distribution of organisms?
Because it limits the rate of photosynthesis
29
How does a lack of nutrients affect the distribution of organisms?
It restricts a plants growth and ability to make proteins because nutrients are found in minerals
30
How are leaves destarched?
By keeping plants in the dark for at least 24 hours
31
How can you see how much starch forms in different conditions?
By changing how much light can reach different parts of the leaves
32
What part of the plant is adapted for photosynthesis?
Chloroplasts
33
Why do leaves take oxygen in the dark?
Because oxygen is needed | To use for aerobic respiration
34
How do the two raw materials for photosynthesis get into the plant?2
- | -
35
Why would the rate of photosynthesis stay the same between two temperatures?2
- | -
36
Why would the rate of photosynthesis decrease after 40 degrees?1
-
37
Why would a part of leaf produce no sugar?2
- | -
38
What is photosynthesis?
The process by which plants make food using carbon dioxide, water and light
39
At night why would carbon dioxide be the limiting factor?
Because in the dark a plant respires instead of photosynthesising
40
How do plants use glucose?4
- for respiration - to convert into insoluble starch for storage - to produce fats or oil for storage - to produce fats proteins or cellulose for use in the cells and cell walls

47
Which part of the plant do mineral salts get in?
Roots
48
Why is water important when obtaining minerals?
Mineral salts are dissolved in water Water transports salts throughout the plant Or Water enables osmosis / diffusion to take place
49
Why would no starch be found in part of a leaf?

Absorbed by the chlorophyll in the chloroplasts This energy is then used to convert carbon dioxide from air plus water from soul into a simple sugar called glucose Produced oxygen as a by product
221
What does the iodine test for starch show?
Yellowy brown liquid It turns dark blue when it reacts with starch You can use this iodine test to show that photosynthesis has taken place
222
why does iodine shoe photosynthesis has taken place?
It shows starch | The glucose made is converted into insoluble starch and stored
223

247
Which part of the plant do mineral salts get in?
Roots
248
Why is water important when obtaining minerals?
Mineral salts are dissolved in water Water transports salts throughout the plant Or Water enables osmosis / diffusion to take place
249
Why would no starch be found in part of a leaf?
No light received so no photosynthesis
250
Why would a leaf not produce sugar?
No chlorophyll so no light can be absorbed
251

How do palisade cells assist photosynthesis?
Near the upper surface of the plant Containing many chloroplasts So contain the most chlorophyll
254
List the ways energy is lost?
Growth Movement Faeces Respiration
255
Why are most leaves broad?
It enables them to have a large surface area for light to fall on
256
Why do leaf contain chlorophyll?
Chlorophyll is contained in the chloroplasts to absorb the light energy
257
Why do leaf have veins?
They bring plenty of water to the cells of the leaves
258
Why do leaf have air spaces?
To allow carbon dioxide to get to the cells | Oxygen to leave them by diffusion

499
Why are algae aquatic?
They are adapted to photosynthesising in water | They can absorb carbon dioxide dissolved in the water around them
500
During photosynthesis how is light energy absorb?
Absorbed by the chlorophyll in the chloroplasts This energy is then used to convert carbon dioxide from air plus water from soul into a simple sugar called glucose Produced oxygen as a by product
501
What does the iodine test for starch show?
Yellowy brown liquid It turns dark blue when it reacts with starch You can use this iodine test to show that photosynthesis has taken place

738
Why do leaf have air spaces?
To allow carbon dioxide to get to the cells | Oxygen to leave them by diffusion
739
Why are algae aquatic?
They are adapted to photosynthesising in water | They can absorb carbon dioxide dissolved in the water around them
740
During photosynthesis how is light energy absorb?
Absorbed by the chlorophyll in the chloroplasts This energy is then used to convert carbon dioxide from air plus water from soul into a simple sugar called glucose Produced oxygen as a by product
741
What does the iodine test for starch show?
Yellowy brown liquid It turns dark blue when it reacts with starch You can use this iodine test to show that photosynthesis has taken place
742
why does iodine shoe photosynthesis has taken place?
It shows starch | The glucose made is converted into insoluble starch and stored
743
Limiting factors of photosynthesis?
Light | Temperature carbon dioxide
744
Why does photosynthesis fall after 40-50 degrees?
Enzymes are denatured once the temperature rises
745
What do plants need carbon dioxide for?
Making glucose
746
Why do plants respire more at night?
More carbon dioxide at night
747
How do plants make amino acids?
They do this by combining sugars with nitrate ions and other mineral ions These amino acids are then built up into proteins to be used in the cells This used energy from respiration
748
Why do plants need nitrate and mineral ions?
By combining sugars with nitrate ions and mineral ions To make amino acids To be built up into proteins
749
How do plants use photosynthesis to build fats and oils?
Used in cells as an energy store Used in cell walls to make them stronger Used in seeds as energy store (to provide lots of energy for the new plant as it germinates)
750
Difference between glucose and starch?
Glucose is soluble in water | Starch is insoluble
751
How is a plant's 'food' moved around the plant?
By the phloem y
752
What would happen if glucose was not converted to starch in a plant?
It would effect the movement of water in the cells

Chlorophyll is contained in the chloroplasts to absorb the light energy
2681
Why do leaf have veins?
They bring plenty of water to the cells of the leaves
2682
Why do leaf have air spaces?
To allow carbon dioxide to get to the cells | Oxygen to leave them by diffusion
2683
Why are algae aquatic?
They are adapted to photosynthesising in water | They can absorb carbon dioxide dissolved in the water around them
2684

3151
Why are algae aquatic?
They are adapted to photosynthesising in water | They can absorb carbon dioxide dissolved in the water around them
3152
During photosynthesis how is light energy absorb?
Absorbed by the chlorophyll in the chloroplasts This energy is then used to convert carbon dioxide from air plus water from soul into a simple sugar called glucose Produced oxygen as a by product
3153
What does the iodine test for starch show?
Yellowy brown liquid It turns dark blue when it reacts with starch You can use this iodine test to show that photosynthesis has taken place
3154

3155
Limiting factors of photosynthesis?
Light | Temperature carbon dioxide
3156
Why does photosynthesis fall after 40-50 degrees?
Enzymes are denatured once the temperature rises
3157

Making glucose
3158
Why do plants respire more at night?
More carbon dioxide at night
3159
How do plants make amino acids?
They do this by combining sugars with nitrate ions and other mineral ions These amino acids are then built up into proteins to be used in the cells This used energy from respiration
3160
Why do plants need nitrate and mineral ions?
By combining sugars with nitrate ions and mineral ions To make amino acids To be built up into proteins
3161
How do plants use photosynthesis to build fats and oils?
Used in cells as an energy store Used in cell walls to make them stronger Used in seeds as energy store (to provide lots of energy for the new plant as it germinates)
3162
Difference between glucose and starch?
Glucose is soluble in water | Starch is insoluble
3163
How is a plant's 'food' moved around the plant?
By the phloem y
3164
What would happen if glucose was not converted to starch in a plant?
It would effect the movement of water in the cells
3165
Why is glucose converted to starch?
Starch has no effect on the water balance of the plant | So plants can store large amounts of starch in their cells

3372
What happens to the glucose in photosynthesis?
Stored as fructose Stored as starch Stored as lipid or oil Moved or transported in phloem Changed to starch Changed to oil or lipid Changed to cellulose
3373
Which part of the plant do mineral salts get in?
Roots
3374
Why is water important when obtaining minerals?
Mineral salts are dissolved in water Water transports salts throughout the plant Or Water enables osmosis / diffusion to take place
3375
Why would no starch be found in part of a leaf?
No light received so no photosynthesis
3376
Why would a leaf not produce sugar?
No chlorophyll so no light can be absorbed
3377
What is needed for photosynthesis?

Chlorophyll is contained in the chloroplasts to absorb the light energy
3383
Why do leaf have veins?
They bring plenty of water to the cells of the leaves
3384
Why do leaf have air spaces?
To allow carbon dioxide to get to the cells | Oxygen to leave them by diffusion
3385
Why are algae aquatic?
They are adapted to photosynthesising in water | They can absorb carbon dioxide dissolved in the water around them
3386
During photosynthesis how is light energy absorb?
Absorbed by the chlorophyll in the chloroplasts This energy is then used to convert carbon dioxide from air plus water from soul into a simple sugar called glucose Produced oxygen as a by product

3401
How can you obtain quantitive data on the distribution of organisms?
Random sampling with quadratic | Sampling along a transept
3402
How do you use a transept?
Stretch a tape between two points Sample at regular intervals using a quadratic This shows how the distribution of organisms changes along a line
3403
Why would you use quantitive sampling?
To compare the distribution of the same organism on different habitats The variety of organisms in a number of different habitats The size of a population of eg plants or slow moving animals
3404
How can a quadrat be used?
Take a number of random readings Find mean number of organism per m2 This is known as quantitive sampling
3405
How can you create a valid investigation?
Appropriate method of sampling You should be able to replicate your method every time Works regardless of who is collecting the data Appropriate size of data
3406

Chlorophyll is contained in the chloroplasts to absorb the light energy
3641
Why do leaf have veins?
They bring plenty of water to the cells of the leaves
3642
Why do leaf have air spaces?
To allow carbon dioxide to get to the cells | Oxygen to leave them by diffusion
3643
Why are algae aquatic?
They are adapted to photosynthesising in water | They can absorb carbon dioxide dissolved in the water around them
3644
During photosynthesis how is light energy absorb?
Absorbed by the chlorophyll in the chloroplasts This energy is then used to convert carbon dioxide from air plus water from soul into a simple sugar called glucose Produced oxygen as a by product
