3. You will needA pen and paper.A digital device.
4. Learning intentionTo identify and understand the function of the parts of cells, known as organelles, and be able to recognise and compare animal and plant cells.
5. Lesson 2: challenge answer Why are cells different sizes in living things?The shape and size of a cell is determined by its function.Cells are shaped to meet their function. Depending on the job of the cell, it will have a shape and size that best suits its job.
6. Cell organelles seen with a light microscopeWatch the video on cell organelles as seen under the light microscope.Write down the function of the following organelles:nucleuscytoplasmcell membranecell wallchloroplastsvacuoles.Source: Parts of the Cell on YouTube (Revision Monkey, 2019)For your safety, watch this video in the slideshow without accessing YouTube
7. Cell organelles in an animal and plant cell Watch the video and take notes on which organelles are found in plant cells and which are found in animal cells or both:nucleuscytoplasmcell membranecell wallchloroplastsvacuoles.Source: Animal and Plant Cells on YouTube (Mark Drollinger, 2014)For your safety, watch this video in the slideshow without accessing YouTube
8. Compare a plant cell to an animal cellAnimal and plant cells have structures in common. However, the differences are veryimportant. Draw a Venn diagram as shown below. Place the following words in the corresponding sections of the Venn diagram to show which structures are common to both types of cells, which are found only in plant cells, and which are found only in animal cells.NucleusCytoplasmCell membraneCell wallChloroplastsVacuolesBelong to both animal and plant cell

11. ReviewCells are made up of organelles as seen under a light microscope.Both animal and plant cells have a nucleus, cytoplasm, vacuoles and cell membrane.Plant cells have a cell wall and chloroplasts.*The answers to the task on cell organelles in an animal and plant cell are written here in points 2 and 3.
12. ChallengeWhat would happen if the nucleus of an animal or plant cell was destroyed?How does the cell wall affect the shape of a plant cell?
