What is the word equation for photosynthesis
Carbon dioxide + water = glucose + oxygen
1 of 19
How do green plants absorb light energy?
The chlorophyll in their leaves
2 of 19
What happens during photosynthesis?
Light energy is abosrbed by the cholorophyll which is found in the cholorplasts this energy is used by converting carbon dioxide and water into glucose
3 of 19
What factors effect Photosynthesis?
Light intensity, Carbon dioxide concentration and temperature
4 of 19
How does temperature effect photosynthesis?
It if gets to cold the rate of photosynthesis decreases and plants cant respire if it gets too hot
5 of 19
Why do plants store glucose?
At night plants cant respire because there is no light so they store it so they can use it later
6 of 19
What do plants store glucose as?
Starch, fats and oils
7 of 19
What are the uses of glucose in plants?
To produce cellulose which strengthens the cell wall and produce protiens such as enzymes and chlorophyll
8 of 19
What are the physical factors that affect organisms?
Temperature, amount of light and avaliability of water, nutrients, carbon dioxide and oxygen
9 of 19
Define: Environment
All the conditions that surround a living organism
10 of 19
Define: Habitat
A place where an organism lives
11 of 19
Define: Population
All the members of a single species that live in a habitat
12 of 19
Define: Community
All the populations of different organisms that live together in a habitat
13 of 19
Define: Ecosystem
A community and the habitat in which it lives
14 of 19
What equiptment can you use to collect quantative data?
Transects and Quadrats
15 of 19
What is a transect and how does it collect data?
A transect is a line across a habitat, the number of organisms of each species can be obcerved and recorded along the transect
16 of 19
What is a quadrat and how does it collect data?
It is a square that contains smaller squares usually 5x5 The organisms underneath the square can be identified and then counted
17 of 19
How do you keep the results from using a quadrat fair?
Placing it randomly, the validity and reproducability of the results increases as the results from more quadrats are analysed
18 of 19
How do you analyse the results from quadrats and transects?
Mean, median and mode
