2.3.3 Identify the structures in 2.2.1 in electron micrographs of a
liver cell
Identify the cell organelles and structures below.
Mitochondrion
Golgi Apparatus

2.3.4 Compare prokaryotic and eukaryotic cells
2.3.4 Compare prokaryotic and eukaryotic cells
2.3.5 State three differences between plant and animal cells
1. Cell wall
Plant cells – cellulose cell wall and
plasma membrane
Animal cells – only plasma membrane
2. Chloroplasts
Plant cells – present in
photosynthetic cells
Animal cells – do not have them
2.3.5 State three differences between plant and animal cells
3. Vacuole
Plant cells – have a large permanent vacuole that is filled
with cell sap
Animals cells – have
small and temporary
vacuoles

4. How food/energy (carbohydrates) is stored
Plant cells – carbohydrates are stored
as starch and plant oils

Animal cells - carbohydrates are
stored as glycogen and animal fat
2.3.6 Outline two roles of extracellular components
Extracellular component – a non-living secretion of a cell (for example cellulose and
cartilage)
Role of cellulose
Provides support and strength for
the cell and tissues of the plant
When the plant cell takes in
water, it limits how much water
can be taken in, and also
prevents the cell from bursting.
This also gives the cell strength
and support (called turgor)

Provides a barrier against disease
and other pathogens

2.3.6 Outline two roles of extracellular components
Roles of cartilage
Gives cushion and lubricates
the joints between bones
Also provides structure to features like the
ears and nose
