Pollen Analysis

Pollen Analysis

How is it measured?

  • Carbon 14 dating is used to establish the age of a particular peat
  • Pollen grains has distictive shapes, features and surface structures

- Pollens taken from its region

- The samples are taken into regular intervals e.g 10cm

- Pollen grains are separated

- Grains are stained

- Using an electron microscope

- To identify different species the plants come from.

Temperature

How is it measured?

  • Using an thermometer
  • 100 stations are put in place all over the globe to measure the average temperature
  • Long term data is recorded

Dendrochronology

Temperature

How is it measured ?

  • By seeing the thickness of the trees rings

~ The wider the rings - the hotter the climate

                                   - Sunny, rainy, moist

~ The narraw the rings - the cooler the climate

                                     - droughts, dry

Global Warming

Global warming

High concentration of greenhouse gasses getting trapped in the atmosphere results to enhanced greenhouse effect.

Light Dependent Reactions

Light Dependent ractions

Light gets absorbed by chlorophyll.

The excited electrons gets boosted up to a higher energy level

The electrons are accepted and passed along a chain of carriers

Enough energy is made to make photophosphorylate

ATP is made by ADP and Phosphate. Reducing NADP is made by NADP and the splitting of water (Photolysis) the H+ is attatch to the NADP they both help make a carbohydrate

Light Independant Reaction

RUBP-- RUBISCO

RUBISCO --- 3 hexose

3 hexose --- GAL

GAL -- GALP

2/12 GALP makes amino acid proteins lipids

10/12 makes
