2. Investigating cells

3. Today we are going to..
We will do this by..
Look at specialised cells in both plants and in animals
Looking at photos
Having class discussions
Answering questions

4. Multicellular Organisms
Plants and Animals have a huge variety of specialised cells which have adapted to perform certain jobs within the organism

5. Specialised cells in HUMANS

6. Red Blood Cells What is their job? What do they look like?
How does that help them do their job better?
Do you know what is unusual about a RBC?

7. White blood cells What is their job? What do they look like?
How does that help them do their job better?

8. Cilliated epithelium What do the “cilia” look like?
What do you think this specialised cell’s job is?

9. Goblet Cell Cup shaped cells which make STICKY mucus
What do you think the job of the mucus is?

10. Motor Neurone Motor neurones carry nerve impulses quickly
What do they look like?
How does that help it with its function?

11. Smooth Muscle Cell
Long and CONTRACTILE
Used in movement

12. Specialised cells in PLANTS

13. Guard cell
Mesophyll
Controls the size of stoma (pore) which allows gas to be exchanged in a plant
Large cells with many chloroplasts at the top of leaves- why?

14. Root Hair epidermal cell
Job is to absorb water from the soil
What features help it carry out this job?
