1. Plant cells
Monday, 04 February 2019

2. Learning objectives:
To understand the similarities and differences between plant and animal cells.

3. How are these different? (5 mins)

4. Circus of activities in the classroom.
Students should work in groups of 2–4 and spend approximately 10 minutes at each station.
A maximum of two groups should be working at each station at the same time.
At one station, three or four light microscopes with prepared slides containing onion cells. Students should use the microscopes to view the slides and draw what they see, adding the size of the cells using the skills they learnt in Lesson 1.
On another station, copy the diagram of the plant cell from page 14 of the Student’s Book and label the parts.
At the final station should be three or four model plant cells. Ask students to state what each part of the model represents in a plant cell. They can use the information on page 14 of the Student’s Book to help them

5. What is a cell? animal cell Plant cell plant cell nucleus cytoplasm
Animal and plant cells come in different shapes
and sizes, but they all have three basic features.
animal cell
Plant cell
plant cell
nucleus
cytoplasm
cell membrane
Plant cells also have some extra features that make them different to animal cells.

7. The parts of a typical plant cell

8. Only plant cells have these: Both types of cell have these:4) 1) 5) 6) 2) 3)
Cell wall – provides support
Cytoplasm - this is where the reactions happen
Nucleus – The “brain” of the cell
Chloroplasts – contain chlorophyll
Cell Membrane – holds the cell together
Large Vacuole – contains sap

9. Comparing cell structure

11. A typical plant cell

12. Collecting plant cell samples
Teacher notes
Cell Worksheet 1 accompanies this section. This worksheet has been designed to be used alongside a practical that involves the students collecting, preparing and studying onion and cheek cells in the lab. However, it could be used alongside the flash activity on slide 23 if the pupils do not have the opportunity to carry out the practical themselves.

13. Questions
Discuss the similarities and differences between plant and animal cells and how these link to what you discussed in the starter activity.
Summarise this by completing the Structured Questions ‘Cells’, questions 1a and 1b.
