Living things and
photosynthesis
- Photosynthesis
- Light?
- Energy from the light drives photosynthesis, so
increasing the amount of light a plant receives
increases the rate of photosynthesis.
- The graph shows us that:
- At low light intensities, increasing
the amount of light increases the
rate of photosynthesis
- At a certain point increasing the
amount of light stops having an effect
on the rate of photosynthesis

- Factors that increase it:
- Light
- Carbon dioxide
- Water
- Chlorophyll
- A higher temperature to
speed up the reaction
- Light
- Limiting factors
- Cold weather
- Winter-Long
periods of
darkness
- Too much water
- Stomata close to prevent water diffusing out of
the leaves, and this also has the unavoidable
consequence of reducing carbon dioxide
diffusion into the leaf.

- Habitats of plants and their locations
- Woodland is a rich habitat for plants and animals.
Sunlight is absorbed by tall trees, which hold their
leaves up for maximum photosynthesis. Some light
gets through from breaks in the canopy and provide
sunlight for some plants. Most of the floor of the
woodland is in shade though so only shady plants
grow there. Each plant has to be specialised to survive
in different conditions.
- Quadrats
- A square grid which is used
to survey the plants in a
square meter.
- Plant growth is recorded as a percentage % and the area the
Quadrat is placed is random. This removes bias' and allows
reliable comparison with two areas. When samples are taken
along a straight line it is called a transect. This is useful to show a
change in environment from areas such as a wood to an open
field.

- Living things
- Made up of cells. Cell-The basic structural
and functional unit of all living things
- Some are single-celled
like bacteria.
- Others have billions of cells like
humans and mammals.
