organism? Mitochondria - makes ATP,
Lysosome - digest bad things,
Nucleus - contains DNA
Ribosomes - synthesize proteins
1. How do you think plant cells differ from animal cells? (Hint: What can plants do that animals
cannot?) Plant cell have chloroplasts that allow them to get their energy from
photosynthesis. Animal cells cannot do so as they receive their energy
from cellular respiration in the mitochondria.
Which organelle is labeled a plant cell?
Which Labelled organelles helped a student to conclude that it is a plant cell * 1 point?
What is the order of organelles from smallest to largest?

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

What are some of the structures inside a cell that help it to live and perform its role in an

organism? Mitochondria - makes ATP,

Lysosome - digest bad things,

Nucleus - contains DNA

Ribosomes - synthesize proteins

1. How do you think plant cells differ from animal cells? (Hint: What can plants do that animals

cannot?) Plant cell have chloroplasts that allow them to get their energy from

photosynthesis. Animal cells cannot do so as they receive their energy

from cellular respiration in the mitochondria.

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.

Use the up/down and left/right sliders to manipulate the cell. Find the red arrow pointing to the centrioles. Make a sketch of the centrioles in the space below.

Read the description of the centrioles. What is their function? Organize the movement of chromosomes during cell division

Activity A: Animal cells

Get the Gizmo ready:  Check that an Animal cell is mounted on the 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?

Label : Locate each organelle in the animal cell. 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 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 protects the nucleus. D. Membrane that surrounds and protects the cell. E. Sac filled with digestive chemicals. F. Structures that converts nutrients to energy. G. Passageways where chemicals are made. H. Jelly-like substance within the plasma membrane. 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.

Prior Knowledge Questions(Do these BEFORE using theGizmo.)

1.What are some of the structures inside a cell that help it to live and perform its role in an organism?

Ribosomes, Nucleus, Chloroplast, etc.

2.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

TheCell StructureGizmo allows you to look at typicalanimal, plant,

and bacterial cells under a microscope. On the ANIMAL CELL tab,

clickSampleto take a sample of an animal cell. On the dropdown

menu, selectCentriole.

3.Find thecentrioles(Highlighted in green).

✏

Makea sketch of the

centrioles in the space below. Either hand draw in the space below or

edit using the drawing tools.

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

Centrioles organize and package proteins

Which organelle is labeled a plant cell?

Plant cells can be distinguished from most other cells by the presence of chloroplasts, which are also found in certain algae.

Which Labelled organelles helped a student to conclude that it is a plant cell * 1 point?

The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.

What is the order of organelles from smallest to largest?

In order from smallest to largest, the answer is atoms, proteins, ribosomes, viruses, mitochondria, a eukaryotic cell.

How can you tell by just looking at a cell if it is a plant or animal cell?

Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
