Name: Kayla Eustaquio, Brianna Cortes, Brianna Monticello Date: 11/10/
Student Exploration: Cell Structure
Vocabulary: cell membrane, cell wall, capsule, centriole, chloroplast, cytoplasm, cytoskeleton, endoplasmic reticulum, flagellum, Golgi apparatus, lysosome, mitochondria, nucleoid, nuclear membrane, nucleolus, nucleus, organelle, pilus, plasmid, plastid, ribosome, vacuole, vesicle
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
- What do you think are some of the structures inside a cell that help it to live and perform its
role in an organism? Ribosomes, Nucleus and Chloroplast
- How do you think plant cells differ from animal cells? (Hint: What can plants do that animals
cannot?) Animal cells don't have a cell wall while plant cells do
_____________________________
Gizmo Warm-up The Cell Structure Gizmo allows you to look at typical animal, plant, and bacterial cells under a microscope. On the ANIMAL CELL tab, click Sample to take a sample of an animal cell. On the dropdown menu, select Centriole.
Find the centrioles (Highlighted in green). Make a sketch of the centrioles in the space below.
Read the description of the centrioles. What is their function? Centrioles organize and package proteins
Activity A:
Animal cells
Get the Gizmo ready: Check that an Animal cell is mounted on the microscope.
Question: Organelles are specialized structures that perform various functions in the cell. What are the functions of the organelles in an animal cell?
Label: Locate each organelle in the animal cell. You can choose organelles from the dropdown menu or click on them directly. Label the organelles in the diagram below.
Match: Read about each organelle. Then match each organelle to its function/description.
H Cytoplasm
E Lysosome F Mitochondria A Centriole G Endoplasmic reticulum M Vacuole D Cell membrane J Nucleus N Cytoskeleton L Ribosome C Nuclear membrane B Golgi apparatus K Vesicle I Nucleolus
A. Structure that organizes motion of chromosomes. B. Stack of membranes that packages chemicals. C. Membrane that surrounds and protects the nucleus. D. Membrane that surrounds and protects the cell. E. Sac filled with digestive chemicals. F. Structures that convert nutrients to energy. G. Passageways where chemicals are made. H. Jelly-like substance within the cell membrane. I. Structure that manufactures ribosomes. J. Structure that contains DNA and regulates genes. K. Package created by the Golgi apparatus. L. Small structure that synthesizes proteins. M. Sac that stores water, nutrients, or waste products. N. Tubules and filaments that give the cell its shape.

Activity B:

Get the Gizmo ready: Select the PLANT CELL tab, and click Sample.
Question: What functions do the organelles in a plant cell perform?
Label: Locate each organelle in the plant cell. Label the organelles in the diagram below.
Compare: What structures are present in an animal cell, but not in a plant cell? Animal cells have centrioles and lysosomes, plant cells do not
What structures are present in a plant cell, but not in an animal cell? Plant cells have cell walls and animal cells don’t.
- Fill in: Name the organelle or organelles that perform each of the following functions.
A. Photosynthesis convert sunlight to chemical energy.
B. The cell wall, the cell membrane, and the Cytoskeleton support the plant cell and
help it to maintain its shape.
C. Vacuoles store food or pigments.
D. Mitochondrion convert food into energy. They are found in plant and animal cells.

Question: How are bacterial cells different from plant and animal cells?
Label: Locate each organelle in the bacterial cell. Label the organelles in the diagram below.
Match: Read about each organelle. Then match each organelle to its function/description.
D Capsule
C Nucleoid
E Plasmid
A Flagellum
B Pilus
A. Hair-like structure that the cell uses for movement. B. Hair-like structure that attaches the cell to a surface and can transfer genetic material from one cell to another. C. Region inside cell that contains genetic material but is not surrounded by a nuclear membrane. D. Outermost layer of the cell that provides protection. E. Circular piece of genetic material.
- Compare: What structures are present in a bacterial cell, but not in a plant or animal cell?
Flagellum, Pilus, Capsule, Plasmid, and Nucleoids
What structures are present in plant and animal cells, but not in a bacterial cell?
