Student Exploration: Cell Structure

Vocabulary​:​ cell membrane, cell wall, centriole, chloroplast, cytoplasm, endoplasmic reticulum, Golgi
apparatus, lysosome, mitochondria, nuclear membrane, nucleolus, nucleus, organelle, 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?

Organelles, mitochondria

2. How do you think plant cells differ from animal cells? (Hint: What can plants do that animals cannot?)

I think that plant cells are different from animal cells because they have chloroplasts
which allow them to photosynthesize.

Gizmo Warm-up
The ​Cell Structure ​Gizmo allows you to look at typical animal and plant cells
under a microscope. On the ANIMAL CELL tab, click ​Sample​ to take a
sample of an animal cell. Use the ​Zoom ​slider to see the cell at a
magnification of 2000x (2000 times larger than normal). On the dropdown
menu, select ​Centrioles​.

1. Use the up/down and left/right sliders to manipulate the cell. Find the
red arrow pointing to the ​centrioles​. ✏ Describe the structure of the
centrioles in the space below.

2. Read the description of the centrioles. What is their function?

They help to organize the movement of chromosomes during cell division.

 Get the Gizmo ready​:
Activity A:
● Check that an ​Animal cell​ is mounted on the
Animal cells microscope.
● Check that the ​Zoom​ is set to 2000x.

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. ✏Label the organelles in the diagram below. Edit using the
drawing tools.

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

H Cytoplasm A. Structure that organizes motion of chromosomes.

E Lysosome B. Stack of membranes that packages chemicals.

F Mitochondria C. Membrane that protects the nucleus.

A Centriole D. Membrane that surrounds and protects the cell.

G Endoplasmic reticulum E. Sac filled with digestive chemicals.

M Vacuole F. Structures that converts nutrients to energy.

D Cell membrane G. Passageways where chemicals are made.

J Nucleus H. Jelly-like substance within the cell membrane.

L Ribosome I. Structure that manufactures ribosomes.

C Nuclear membrane J. Structure that contains DNA and regulates genes.

B Golgi apparatus K. Package created by the Golgi apparatus.

K Vesicle L. Small structure that synthesizes proteins.

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

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

1. Label​: Locate each organelle in the plant cell. ✏Label the organelles in the diagram below.Either hand
draw in the space below or edit using the drawing tools.

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

Centrioles and lysosomes

What structures are present in a plant cell, but not in an animal cell?

Chloroplasts and Plastids

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

A. Chloroplasts convert sunlight to chemical energy.

B. The Vacuole and the Cytoplasm

C. Plastids store food or pigments.

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