NAME: __________________________________________ PERIOD: _________________ Student Exploration: Cell Structure Vocabulary: Cytoplasm, Endoplasmic Reticulum, Ribosomes, Mitochondria, Vacuole, Nucleus, Cell Wall, Chloroplast. (There are other cell parts in this activity, but these will be our focus today) Structures of a Typical Animal Cell In this activity, you will examine the structure of a typical animal cell. Gizmo Warm-Up In the Gizmo, select View animal cell from the dropdown menu and click Sample. An animal cell moves to the stage. Drag the Zoom slider to the right until it reads 200x and briefly examine the cell. Drag the Zoom slider to the right once again, this time until it reads 500x. Use the sliders at the bottom and at the right to move the cell around. 1) From the dropdown menu at the left, select Cytoplasm. (A small red arrow is pointing at the plasma membrane to help you find it.) Read the information about the cytoplasm. An arrow will point to the cell part on the diagram. The cytoplasm is a ___________________________ substance composed mostly of _________________________________. What are found in the cytoplasm? ___________________________________ 2) Select Endoplasmic reticulum from the dropdown. Find the structure within the cell and read the description provided. What does ER do in the cell? ___________________________________________ What cell structures cover the rough ER? ___________________________________ Select Ribosomes and read the accompanying description. What function do the ribosomes serve? __________________________________. Select Mitochondrion and read the information. Find a mitochondrion in the viewing area. Which of the pictures to the right is a mitochondrion?_______ What is the function of the mitochondrion? _________________________________ Select Vacuole. What can be stored in the vacuole? _____________________________________________ Increase the magnification to 1000x and center the purple region (the nucleus) in the middle of the cell in the viewing area. Select Nucleus. Why is the nucleus referred to as the "brain" of the cell? ________________________ _______________________________________________________________________ What is contained in the nucleus? __________________________________ Structures of a Typical Plant Cell In this activity, you will examine the basic structures of a typical plant cell and compare and contrast them with those of an animal cell. Select View plant cell from the dropdown menu above the viewing area. Click Sample. Use the Zoom slider to magnify the cell 200x. Examine the plant cell. In general, how does a plant cell look different from an animal cell? ________________________________________________________________ Move the slider to increase the magnification to 500X Select Cell wall from the dropdown menu. Where is the cell wall? ___________________________________________________________________ What is the function of the cell wall? ___________________________________________________________________ Select Chloroplast. Would you expect to find chloroplasts in animal cells? Why or why not? ____________________________________________________________________ Match the cell part to the function: (you may want to use your notes too!) ____ Cytoplasm ____ Lysosome ____ Mitochondria ____ Endoplasmic reticulum ____ Vacuole ____ cell (plasma) membrane ____ Nucleus ____ Ribosome ____ Golgi apparatus (body) A. May contain food, water, or waste B. Surrounds and protects the cell and lets some things go through it. C. Sac where wastes are digested D. Structures that makes energy E. Passageways where chemicals are made. F. Jelly-like substance within the cell G. The ribosomes are located on this organelle H. Structure that contains DNA and directs the cell’s activities I. Makes protein Complete the 5 question quiz on the gizmo Question 4 is C (we have not studied this one yet
