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 http://botany.thismia.com/2010/02/24/plasmolysis/

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 bioweb.wku.edu 4. How food/energy (carbohydrates) is stored Plant 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 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) http://kscience.co.uk/animations/turgor.swf Provides a barrier against disease and other pathogens treehugger.com

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
