- Cnucleus
5where do chemical reactions take place?
- Astomata
- Bchlroroplasts
- Cnucleus
6what happens if if too much simple sugar is dissolved into the cell sap of plants?
- Amake a very concentrated solution. And water would move into the cells by osmosis and cause the cells to swell up, making them have a very thick cell wall.
- Bnothing-.-
- Cmake a very concentrated solution. and the water would move out of the cells, making them wilt
7what are the requirements for photosynthesis?
- Alight, chlorophyll, oxygen, carbon dioxide
- Blight, chlorophyll, glucose, carbon dioxide

- B1. raw materials 2. provides energy 3. absorbs sunlight 4. raw material
9what are the products of photosynthesis?
- Aglucose and oxygen
- Bglucose and carbon dioxide
- Ccarbon dioxide and water
10what are the products of photosynthesis?
- Aglucose and oxygen
- Bglucose and carbon dioxide
- Ccarbon dioxide and water

14glucose is also converted into...
- Aproteins for growth and repaire
- Bproteins, for respiration
- Cchlorophyll, to absorb light
15glucose is also converted into...
- Aproteins for growth and repaire
- Bproteins, for respiration
- Cchlorophyll, to absorb light
16what else are proteins used for?
- Aphotosythesis
- Benzymes and hormones
- Cenergy
17glucose is also converted into...
- Achloroplasts
- Bsugars and oils, to store energy in seeds
- Cnothing else
18why is oxygen a by-product of respiration?
- Ait is not the main product, and is not used by the plant
- Bit is not the main product, but is used by the plant
- Cit is not needed
19what effect the rate of photosynthesis?
- Alight, carbon dioxide, water
- Blight, carbon dioxide, temperature
- Clight, carbon dioxide, water , temperature
20only one factor can limit the rate of photosynthesis at any one time
- ATrue
- BFalse
21why are crops grown in green houses?
- Athey can grown in places they dont usually grow
- Byou can make them grow earlier in the year
- Call of the above
22 temperature in a green house is controlled by sunlight, glass, heaters and ventilator flaps
- ATrue
- BFalse
23leaves have...
- Aa large surface area- to absorb light
- Ba small surface area- to make sure water vapor doesnt escape
- Ca thin shape- so that gasses can diffuse in and out easily
- Dmany chloroplasts- to absorb light
- Eveins- to absorb water
- Fveins- to support the leaf and carry water around
24what does the cuticle do?
- Aabsorb sunlight
- Bprevent water getting into the leaf and cuts down evaporation
25stomata are
- Asmall holes in the epidermis which allow gases to diffuse in and out
- Bsmall holes that absorb water
- Csmall holes that absorb sunlight
26stomata are usually in the..
- Aupper epidermis
- Blower epidermis
27ions are absorbed into the soil by active transport
- ATrue
- BFalse
28plants need nitrate ions to make
- Aenergy
- Bamino acids
29describe a magniesuim lack in plants
- Aused to make chlorophyll: the leaves look yellow and pale: this mineral is used for photosynthesis
- Bused for respiration: plant is yellow
30describe a lack of pottassium
- Aleaves are yellow: used for photosynthesis: must be present for respiration
- Bdc
31describe a lack of phosphate
- Aroots are small and leaves are purple: used for respiration and growth: component of DNA molecules
- Bsmall and leaves are yellow: used for building proteins and growth: animo acids are the building blocks of protein
32describe a lack of nitrate
- Asmall and leaves are yellow: used for building proteins and growth: animo acids are the building blocks of protein
- Bsmall roots and leaves are purple: used for respiration and growth: component of DNA
33NPK fertilisers contain
