Plant cells Saturday, June 5, 2021
Learning objectives: • To understand the similarities and differences between plant and animal cells.
How are these different? (5 mins)
• 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
What is a cell? Animal and plant cells come in different shapes and sizes, but they all have three basic features. Plant cell animal plant cell nucleus cytoplasm cell membrane Plant cells also have some extra features that make them different to animal cells.
1. 2 a Plant or animal cell? Plant cell vacuole cytoplasm chloroplast nucleus cell wall cell membrane
The parts of a typical plant cell
Both types of cell have these: 1) Cytoplasm this is where the reactions happen 2) Nucleus – The “brain” of the cell 3) Cell Membrane – holds the cell together Only plant cells have these: 4) Cell wall – provides support 5) Chloroplasts – contain chlorophyll 6) Large Vacuole – contains sap

Collecting plant cell samples
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 1 a and 1 b.
