What is fermentation?
When microorganisms break down sugars into other products as they respire anaerobically
18 of 34
List some human uses of fermentation
Bread, Alcohol, Biogas

What is photosynthesis?
A series of chemical reactions that uses energy from sunlight to produce food (glucose)
20 of 34
In what organisms does photosynthesis take place in?
plants cells and some microorganisms (phytoplankton)
21 of 34
Why is chlorophyll essential for photosynthesis to happen?
Its a green substance which absorbs sunlight and allows energy to be used to convert carbon dioxide and water into glucose.
22 of 34
List three main ways that plants use glucose
Respiration, making chemicals for growth (for making cell walls, amino acids, chlorophyll), stored as starch
23 of 34
What are the three factors that can affect the rate of photosynthesis?
Amount of light, Amount of CO2, Temperature
24 of 34
If a plant has a light increase, why will the rate of photosynthesis only rise until a certain point?
Because light is no longer the limiting factor, you now need a carbon dioxide increase or temperature increase to keep increasing this rate.
25 of 34
What happens if the temperature gets to hot for a plant?
The enzymes needed for photosynthesis to work denature
26 of 34
What is a transect?
A way of investigating how something changes across an area
27 of 34
What is a light meter?
A sensor that accurately measures light level
28 of 34
How do you use a quadrat?
You estimate the percentage cover of a plant species on the ground by counting how much of the quadrat is covered by a species
29 of 34
What is an identification key?
A series of questions that is used to identify what plant species you're looking at

What is diffusion?
The passive overall movement of particles from a region of their high concentration to a region of their lower concentration
31 of 34
What is osmosis?
The overall movement of water molecules from a dilute to a more concentrated solution across a partially permeable membrane
32 of 34
What is active transport?
The overall movement of chemicals across a cell membrane from a region to lower concentration to a region of higher concentration using energy released by respiration
33 of 34
Give an example of active transport
Plants take in minerals (nitrates) by their roots through active transport. The concentration of minerals in the roots is usually higher then the soil surrounding them
