A Cellular Adventure

Nov 18­8:52 PM

Cytoplasm• Jelly­like substance.

• Breaks down molecules to produce energy.

• Builds other molecules up.

Cytoplasm

Nov 18­8:53 PM

Lipid• Organic compounds like fats, oils, and waxes.

• Are used for structure and to store energy.

Nov 18­8:52 PM

Cell Membrane• Thin, outer layer of the cell.

• Holds organelles in place.

• Imports and exports nutrients.

• Passes waste and other materials to the outside of the cell.

• The “Gate Keeper”

of the cell.

Cytoplasm

Nov 18­8:53 PM

Ribosomes• Can synthesize, or make, proteins.

• Passes the proteins into the cytoplasm.

• Found on the outside of the rough endoplasmic reticulum and in the cytoplasm.

Nov 18­8:53 PM

Rough Endoplasmic Reticulum

• Makes large macromolecules like proteins, lipids, and carbohydrates.

• Separates molecules.

• Transports proteins inside the cell and to other parts of the body.

Smooth Endoplasmic Reticulum

• Not covered with ribosomes.

Can synthesize, or make, lipids (fats, oils, and waxes).

Nov 18­8:53 PM

Golgi Body• Collects, modifies, packages substances manufactured by the cell.

Nov 18­8:54 PM

Lysosome• Breaks down worn­out organelles, debris, and ingested particles.

• The “Trash Can” of the cell.

Nov 18­8:54 PM

Vacuole• Storage area for the cell.

• Keeps materials such as food, until the cell needs them.

• The “Suitcase” of the cell.

Nov 18­9:06 PM

Mitochondria• Uses sugars and fatty acids to generate energy for the cell.

• The “Powerhouse” of the cell.

Nov 18­9:06 PM

Nucleus• Directs all activities inside the cell.

• Manages cell division.

• The “Control Center” of the cell.

Nucleolus• Synthesizes, or makes, ribosomes.

Nov 18­9:06 PM

Nuclear Membrane• Separates the nucleus from the cytoplasm.

• Contains the DNA, chromosomes, and genes of the cell.

Nov 18­9:07 PM

Cell Wall• The rigid outer wall of a plant cell.

• Provides structure so the plant can stand up straight.

Nov 18­9:07 PM

Chloroplasts• Has chlorophyll inside that allows the plant to carry out photosynthesis.

• Photosynthesis combines carbon dioxide and water to make food for the cell.
