What is the Function and Structure of the Nucleus?
Structure: The Jelly-like material that is within the cell and is enclosed by the cell membrane.
Function: Converts light energy into chemical energy
Structure: A large, oval-shaped structure that is enclosed in a membrane.
Function: Contains the genetic material responsible for controlling the activities of the cell
What is the Function and Structure of the Vacuole?
Structure: Large, round sac that is filled with fluid
Function: Stores water, food, or waste materials for the cell
Structure: Bean- or peanut-shaped with internal membranes
Function: Gives support to the organelles within the cell
What is the Function and Structure of the Mitochondria?
Structure: Bean- or peanut-shaped with internal membranes.
Function: Breaks down sugars to release energy in a form usable by the cell; the powerhouse of the cell.
Structure: Green, oval-shaped structure that contains chlorophyll
Function: Regulates the passage of materials in and out of the cell, protects and gives some structure.
What is the Function and Structure of the Cell Membrane?
Structure: A porous, thin tissue that forms the outer surface of the cytoplasm.
Function: Converts light energy into chemical energy.
Structure: A porous, thin tissue that forms the outer surface of the cytoplasm.
Function: Regulates the passage of materials in and out of the cell, protects and gives some structure.
What is the Function and Structure of the Chloroplast?
Structure: Green, oval-shaped structure that contains chlorophyll
Function: Converts light energy into chemical energy.
Structure: Bean- or peanut-shaped with internal membranes.
Function: Contains the genetic material responsible for controlling the activities of the cell.
Which model is a Animal Cell?
Which model is a Plant Cell?
Check mark all that apply. How can you tell the difference between a Plant Cell and an Animal Cell? (Hint there's more than one right answer)
Plants Cells have Mitochondria and Animal Cells do not
Plant cells have a Cell Wall and Animals cells do not
Animal cells have many, small Vacuoles. Plant cells have one large Vacuole.
Animal cells do not have Chloroplast, but Plant cells do.
Plant cells have a square shape and Animal cells have a circle shape.
Which statement BEST describes all living things?

Vacuole
Nucleus
Mitochondria
Chloroplasts
The site of photosynthesis in a plant cell is the...
Cytoplasm
Chloroplast
Mitochondria
Cell wall
Which BEST describes the function of the nucleus of a cell?
The “powerhouse”; produces energy
The “gatekeeper” ; lets materials in and out
The “control center”; controls activities and stores genetic material
The “support structure” ; rigid, strong, stiff outer layer
This organelle is responsible for storing food, water, and waste.
Cytoplasm
