Vocabulary


Nucleus- An internal compartment that houses the cell's DNA.

Mitochondria- Orgenelle that produces much of the ATP made by a eukaryotic cell.

Cell Membrane- Liquid bilayer with embedded protiens that enclose the cytoplasm essential to the cell's cytoplasm also called the plasm membrane.

Ribosome- Orgenelle on which protiens are made.

Golgi Apparatas- An orgenelle that packages and distributes molecules produced by a eukaryotic cell.

Endoplasmic Reticulumn- Cell membrane in the cytoplasm that transport substances made by the cell.

Liysosome- Orgenelle in a eukaryotic cell that contains digestive enzymes.

Vacuole- Membranebound cavity in plant cells used for storage.

Chloroplast- Organelle that uses light energy to make carbohydrates from carbon dioxide and water.

Catapult


I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. III. For every action there is an equal and opposite reaction.
