Animal Cells and Plant cells Lesson Objectives 1) To be able to correctly label the main parts of animal and plant cells 2) To be able to describe their functions 3) Know some examples of cells Animal and plant cells Here is a picture of a plant cell and an animal cell. Cells are the smallest units of life. Some cells can exist on their own, whilst others are found in groups. Humans are a collection of many billions of cells, all working together. What is a cell? Label these Cells on your sheet. Nucleus Cell Membrane Cytoplasm Cell Wall Vacuole Chloroplast Plant Cell Animal Cell The Cell - a living factory! Role Check Do all cells look the same? We now know that most cells have three basic parts. These are the: Nucleus However, cells can be different shapes and sizes and also have different functions. This is because they are… Cytoplasm Cell Membrane Specialised This means that their shape is related to their function. Let us look at some animal cells These are common animal cells. Scraped from a person’s cheek. OWWW! Animal Cells Nucleus Animal Cells Cytoplasm Nucleus Animal Cells Cytoplasm Nucleus Membrane Plant Cells Plant Cells Notice the rigid shape from the cell wall. Plant Cells The black dots are the nuclei Plant Cells have something else too. Do you know what’s missing? Chloroplasts! These are the green bits Of course all of these cells add up to make a beautiful… Plant or flower! Plants have specialised cells too… Think about what plants need to survive: Water Sunlight CO2 Plants draw up the water from the soil… The root looks like this close up Plants also need Carbon Dioxide. These pictures you can see are special holes, called stomata. They are found on the underside of some leaves. Sunlight is turned into food Sunlight is absorbed by the chloroplasts in the leaves. Chloroplasts contain chlorophyll, which is green. Sunlight is absorbed by the chloroplasts Remember those green bits?
