2.5.1 Cell Structure

Vocabulary: cell wall, centriole, chloroplast, cytoplasm, endoplasmic reticulum, Golgi apparatus, lysosome, mitochondria, nuclear envelope, nucleolus, nucleus, organelle, plasma membrane, plastid, ribosome, vacuole, vesicle

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. What are some of the structures inside a cell that help it to live and perform its role in an organism? ______Mitochondria, nucleus, ribosome’s. __________________________________________________________ _________________________________________________________________________

2. How do you think plant cells differ from animal cells? (Hint: What can plants do that animals cannot?) ___Plants can produce their own food through photosynthesis . _______________________________________________________________ _________________________________________________________________________

Gizmo Warm-up
The Cell Structure Gizmo™ allows you to look at typical animal and plant cells under a microscope. To start, click Sample to take a sample of an animal cell. Use the Zoom slider to see the cell at a magnification of 1000x (1000 times larger than normal).

1. Use the up/down and left/right sliders to manipulate the cell. Find the red arrow pointing to the centrioles. From the internet, find a new picture of a centriole and paste it here. Please include the web address you got it from.

2. Read the description of the centrioles. What is their function? _______They help organize the movement of chromosomes during cell division.

|Activity A: |Get the Gizmo ready: |[pic] | | |Check that an Animal cell is mounted on the microscope. | | |Animal cells |Set the Zoom to 500x. | |

Question: Organelles are specialized structures that perform various functions in the cell. What are the functions of the organelles in an animal cell?

1. Label: Locate each organelle in the animal cell. Insert text boxes to label the organelles in the diagram below.

2. Match: Read about each organelle. Then match each organelle to its function/description.

___H_ Cytoplasm

___K_ Lysosome

__F__ Mitochondria

I. Structure that manufactures ribosomes.

J. Structure that contains DNA and directs the cell.

K. Package created by the Golgi apparatus.

L. Small structure that synthesizes proteins.

M. Sac that stores water, nutrients, or waste products.

|Activity B: |Get the Gizmo ready: |[pic] | | |Select View plant cell, and click Sample. | | |Plant cells |Set the Zoom to 500x. | |

Question: What functions do the organelles in a plant cell perform?

1. Label: Locate each organelle in the plant cell. Insert text boxes to label the organelles in the diagram below.

2. Compare: What structures are present in an animal cell, but not in a plant cell? ____Lysosomes are present in animal cells______

_________________________________________________________________________

What structures are present in a plant cell, but not in an animal cell? ________Mitochondrion are in plant cell, Cell wall, Chloroplast, Plastids/__________

_________________________________________________________________________

3. Fill in: Name the organelle or organelles that perform each of the following functions.

A. _______Chloroplast______________ convert sunlight to chemical energy.

B. The __________Cell Wall___________ and the _______Plasma Membrane______________ help to support the plant cell and help it to maintain its shape. C. _________plastids____________ store food or pigments.

D. The __________Mitochondria___________ converts food into energy. It is found in both plant cells and animal cells. -----------------------
