B7.1 Living organisms are interdependent.

1. understand that all organisms are ultimately dependent on energy from

the Sun;

2. recall that plants absorb a small percentage of this energy for the

process of photosynthesis;

3. recall that this energy is stored in the chemicals which make up…

B7.2 Photosynthesis.

1. recall the equation for photosynthesis:

light energy

carbon dioxide + water Æ glucose + oxygen

2. recall the main stages of photosynthesis:

a. light energy absorbed by the green chemical chlorophyll;

b. energy used to rearrange the atoms of carbon dioxide and water to

produce glucose…

3. recall the equation for aerobic respiration:

glucose + oxygen Æ carbon dioxide + water (+ energy released)

4. understand that energy released during respiration is used to

synthesise a chemical called ATP;

5. understand that ATP can be referred to as the "energy currency" of

living things;

6. recall…

1. recall the components of blood and their functions:

a. red blood cells ­ transporting oxygen;

b. white blood cells ­ fighting infection;

c. platelets ­ blood clotting at injury sites;

2. recall that the ABO blood type system describes:

a. antigens on the surface of red blood cells;

3. understand that muscles can only move bones at a joint by contraction,

and thus operate in antagonistic pairs;

4. recall the outline structure of a joint to include:

a. smooth layer of cartilage to prevent the bones rubbing together;

b. synovial fluid which is oily and helps joint movement;…
