2.3.3 Identify the structures in 2.2.1 in electron micrographs of a liver cell

Identify the cell organelles and structures below.

Nucleus

Plasma membrane

Rough endoplasmic reticulum

2.3.3 Identify the structures in 2.2.1 in electron micrographs of a liver cell

Identify the cell organelles and structures below.

Golgi Apparatus

Lysosome

Mitochondrion

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 wallPlant cells – cellulose cell wall and plasma membraneAnimal cells – only plasma membrane

2. ChloroplastsPlant cells – present in

photosynthetic cells

Animal cells – do not have them

2.3.5 State three differences between plant and animal cells

3. VacuolePlant 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 storedPlant cells – carbohydrates are

stored as starch and plant oils

home.comcast.net 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 celluloseProvides support and strength for

the cell and tissues of the plantWhen 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
