topic: Cells activity: Comparing plant and animal cells Students explore the differences between plants and animals at both a macroscopic and cellular level. Suggested time: 25 minutes Summary of Key Learning Points Students: - identify the similarities and differences between plants and animals at a macroscopic level - compare plants and animals at a cellular level - summarise the similarities and differences between plants and animals Comparing plant and animal cells 5 minutes Students start by looking at a mongoose in a natural setting, so both an animal and a plant are visible. They are prompted to think about how animals and plants differ in their behaviour. It would be good to get students to brainstorm their ideas about all the ways that animals and plants are similar and different. Hopefully they will recognise that both possess the seven characteristics of living things, but plants can photosynthesise and animals move a lot more. Some animals also need to maintain a constant body temperature. Answers: Animals: Rapid movement Both: Respiration, excrete waste, grow, reproduce Plants: Photosynthesis (Inquiry point 1) The next page shows an animal cell and a plant cell. Now, students compare the two cells and they can also think about other cells they might have seen under the microscope. Answers: Shape: Different Colour: Different Organelles: Some different (Inquiry point 2) Exploring plant cells © IntoScience 2013.

Answer: Chloroplasts (Inquiry point 3) Mitochondria (Inquiry point 4) The Science extra on photosynthesis shows the chemical equation for the process. Talking point: What do the numbers in the formulas mean? Also look at the Science extra on respiration. This looks like the direct opposite of photosynthesis, but is it? Comparing plant and animal cells 5 minutes Students then think about which organelle animal cells need more of. Emphasise to students that animals need far more energy than plants. Answers: Animal cell (needs more mitochondria) (Inquiry point 5) Exploring animal cells 5 min Looking at the animal cell close up allows students to complete a drag drop exercise. Answers (in order): a lot more, have no, large, have no (Inquiry point 6) Comparing plant and animal cells (3) 5 minutes Students finish the activity by looking at a venn diagram that summarises similarities and differences between plant and animal cells. After reading the diagram, students enter challenge mode and gradually reconstruct the diagram by making the correct choices. They can re-try the challenge as many times as they like. (Inquiry point 7) Suggested completion levels © IntoScience 2013. This sheet may be reproduced for classroom use Page 2/3 topic: Cells activity: Comparing plant and animal cells Basic - Inquiry point goal = 2 Students at this level will: identify one similarity and one difference between plants and animals at both the macroscopic and cellular levels. Core - Inquiry point goal = 5 Students at this level will: identify at least two similarities and two differences between plants and animals at both the macroscopic and cellular levels. Advanced - Inquiry point goal = 7 Achieve all inquiry points. Students at this level will: identify at least three similarities and three differences between plants and animals at both the macroscopic and cellular levels. © IntoScience 2013.
