2. Cell biology

3. Cell Structure and Function
National 5 Cell Biology
Cell Structure and Function

4. We are learning to: Identify different cell types
Identify the parts of cells
State the function of the parts of the cells
Describe similarities and differences between different cell types

5. What I'm looking for:
Table showing the different functions of each part of the cells
Labelled diagrams of each cell type
A sentence to describe the similarities and differences between the different cell types

6. Animal and Plant Cells
Plant and Animal cells

7. Activity One Watch the video “What is a cell?” closely
You will use this information to complete a table

8. Activity One
Start Timer 7
Using information from the video and in your booklet- complete table in your booklet
3.5

9. Organelle
Cells present in
Function
Cell wall
Plant, fungal and bacterial
Provide shape and support to the cell
Mitochondria
Animal, plant and fungal
Site of aerobic respiration
Chloroplasts
Some plant cells
Site of photosynthesis
Cell membrane
All cells
Controls the movement of substances in and out of cells
Cytoplasm
Site of chemical reactions
Vacuole
Plant and fungal
Fluid filled sac containing water, sugars and salts
Nucleus
Controls cell activities and contains genetic information
Ribosome
Site of protein synthesis
Plasmids
Bacterial
Small circular DNA

10. Activity Two
Using the information provided, match the organelle function and picture with its name
Check with your teacher
Label diagrams in your summary booklet

14. Bacterial Cell

15. Activity Three Describe the similarities and differences between
Plant and animal cells
Plant and fungal cells (Hint! Mention the cell wall)
Fungal and bacterial cells (Hint! Think of organelles)

16. Plant and Animal Cells Similarities Differences Nucleus Cell membrane
Cytoplasm
Ribosome
Mitochondria
Plant cells also have a
cell wall
chloroplast
vacuole

17. Plant and Fungal Cells Similarities Differences Nucleus Cell membrane
Cytoplasm
Ribosome
Mitochondria
The cell wall of a plant cell is made of cellulose
Fungal cells do not have chloroplasts- cannot make their own food

18. Fungal and Bacterial Cells
Similarities
Differences
Ribosome
Cell membrane
Cytoplasm
Cell walls are structurally different
Fungal cells have mitochondria, nucleus and a vacuole
Bacterial cells do not have a nucleus, contain extra DNA plasmids

19. I can: Identify different cell types Identify the parts of cells
State the function of the parts of the cells
Describe similarities and differences between different cell types
