Students should understand that meiosis leads to non-identical cells
being formed while mitosis leads to identical cells being formed.
Sexual reproduction involves the joining (fusion) of male and female
gametes:
• sperm and egg cells in animals
• pollen and egg cells in flowering plants.
In sexual reproduction there is mixing of genetic information which leads
to variety in the offspring. The formation of gametes involves meiosis.
Asexual reproduction involves only one parent and no fusion of gametes.
There is no mixing of genetic information. This leads to genetically
identical offspring (clones). Only mitosis is involved.

Students should be able to explain that homeostasis is the regulation
of the internal conditions of a cell or organism to maintain optimum
conditions for function in response to internal and external changes.
Homeostasis maintains optimal conditions for enzyme action and all cell
functions.
In the human body, these include control of:
• blood glucose concentration
• body temperature
• water levels.
These automatic control systems may involve nervous responses or
chemical responses.
All control systems include:
• cells called receptors, which detect stimuli (changes in the
environment)
• coordination centres (such as the brain, spinal cord and pancreas)
that receive and process information from receptors
• effectors, muscles or glands, which bring about responses which
restore optimum levels.
Interactive Trivia. Useful For AFL or Revision
Students should be able to explain how the main sub-cellular structures,
including the nucleus, cell membranes, mitochondria, chloroplasts in
plant cells and plasmids in bacterial cells are related to their functions.
Most animal cells have the following parts:
• a nucleus
• cytoplasm
• a cell membrane
• mitochondria
• ribosomes.
In addition to the parts found in animal cells, plant cells often have:
• chloroplasts
• a permanent vacuole filled with cell sap.
Plant and algal cells also have a cell wall made of cellulose, which

Students should be able to describe cellular respiration as an
exothermic reaction which is continuously occurring in living cells.
The energy transferred supplies all the energy needed for living
processes.
Respiration in cells can take place aerobically (using oxygen) or
anaerobically (without oxygen), to transfer energy.
Organisms need energy for:
• chemical reactions to build larger molecules
• movement
• keeping warm.
Aerobic respiration is represented by the equation:
glucose + oxygen carbon dioxide + water
Students should recognise the chemical symbols:
C6
H12O6
, O2
, CO2
and H2O.

Students should be able to explain how the structures of plant tissues
are related to their functions.
Plant tissues include:
• epidermal tissues
• palisade mesophyll
• spongy mesophyll
• xylem and phloem
• meristem tissue found at the growing tips of shoots and roots.
The leaf is a plant organ. Knowledge limited to epidermis, palisade and
spongy mesophyll, xylem and phloem, and guard cells surrounding
stomata.

Based on AQA biology specification:
During exercise the human body reacts to the increased demand for
energy.
The heart rate, breathing rate and breath volume increase during
exercise to supply the muscles with more oxygenated blood.
If insufficient oxygen is supplied anaerobic respiration takes place in
muscles. The incomplete oxidation of glucose causes a build up of
lactic acid and creates an oxygen debt. During long periods of vigorous
activity muscles become fatigued and stop contracting efficiently.
(HT only) Blood flowing through the muscles transports the lactic acid
to the liver where it is converted back into glucose. Oxygen debt is the
amount of extra oxygen the body needs after exercise to react with the
accumulated lactic acid and remove it from the cells.

Anaerobic respiration in muscles is represented by the equation:
glucose lactic acid
As the oxidation of glucose is incomplete in anaerobic respiration much
less energy is transferred than in aerobic respiration.
Anaerobic respiration in plant and yeast cells is represented by the
equation:
glucose ethanol + carbon dioxide
Anaerobic respiration in yeast cells is called fermentation and has
economic importance in the manufacture of bread and alcoholic drinks
