Essential Questions 1 How are prokaryotic cells and eukaryotic cells similar and how are they different? 2 What do the structures in a cell do?

Explore Activity The Right Tools for the Job • Imagine that you are teaching someone to use some everyday objects. • They have never seen or heard of the objects that have been provided, so it is up to you to explain their use. • Illustrate or describe the function of these objects using only structure as your clues.

Cell Shape and Movement Recall that all living things are made up of one or more cells. As illustrated in the images provided, cells come in many shapes and sizes. The size and shape of a cell relates to its job or function.

Cell Types Recall that the use of microscopes enabled scientists to discover cells. With more advanced microscopes, scientists discovered that all cells can be grouped into two types—prokaryotic (proh kayr ee AH tihk) cells and eukaryotic (yew kayr ee AH tihk) cells.

Cell Organelles are eukaryotic cell structures with specific functions. Organelles enable cells to carry out different functions at the same time.

Mini-Assessment 4. Rosa uses a microscope to look at a group of cells, as shown above. She sees that the cells are joined together, so she knows that they are from one organism. She also sees that all of them have cell walls. Rosa could be looking at A bacterial cells C mouse cells B human cells D mushroom cells CORRECT

Mini-Assessment 5. Which structure creates energy for the cell in the form of ATP? A lysosome C endoplasmic reticulum B mitochondrion D Golgi apparatus CORRECT
