1 Cell Structure

2 Animal Cells Do not have a regular shape Some can alter their shape
eg. Phagocytes or amoeba Contain some different organelles than plants

3 Centrioles Associated with cell division Composed of microtubules
Anchor fibres to separate chromosomes during cell division

4 Vacuoles Smaller than those found in plant cells Not used for support
Storage of water, food or waste.

5 Animal Cell Specialisation
Draw a small sketch of the following examples on your handout. Cells have special features to enable them to carry out their function See handout

6 Sperm Cell Nerve cell

7 Epithelial cell Ciliated epithelium

8 Red Blood Cell White Blood Cell

9 Muscle Cell

10 Plant cells Hold a fixed shape Enclosed in a cellulose wall
Have parts animal cells don’t

11 Cell Wall Composed of cellulose Protects
Supports cell and maintains shape Limits cell volume preventing excessive water uptake

12 Large vacuole Filled with aqueous solution of ions Prominent Storage
Waste disposal Growth

13 Chloroplast Contain chlorophyll Used for photosynthesis

14 Plant Cell Specialisation
Draw a small sketch of the following examples on your handout. Cells have special features to enable them to carry out their function See handout

15 Root hair cell Palisade cell

16 Guard cell Pollen grain

17 Xylem and Phloem
