The cell contains structures called organelles that perform all of the tasks needed to keep an organism alive. These tasks include processing information, providing energy, transporting materials, and getting rid of waste.

As you tour the animal cell, you will see many of the organelles and learn about what they do. A Gelatin-like material called cytoplasm fills the cell; organelles float around in the cytoplasm. Chemicals in the cytoplasm also break down large molecules for other parts of the cell to use.

The nucleus contains all the genetic material for the cell; it is the cell's command center, directing all of the cell's activities.

Mitochondria provide energy for the cell; they use oxygen to release energy from food taken in by the cell.

Endoplasmic reticulum is a system of winding membranes that packages and transports materials; it also manufactures parts of the cell membrane.

Ribosomes are found in the cytoplasm and on the endoplasmic reticulum. Ribosomes build proteins by connecting amino acids into long chains.

The Golgi apparatus takes simple materials, made in the endoplasmic reticulum, and processes them into more complex materials. Once the Golgi apparatus has processed these materials, they are either stored or sent out of the cell.

Vesicles are small packages that store and transport materials. Some vesicles are formed when parts of the endoplasmic reticulum break off; these vesicles carry materials to the Golgi apparatus. Other vesicles are formed when parts of the Golgi apparatus break off; these vesicles help to transport materials out of the cell.

Lysosomes are a type of vesicle made by the Golgi apparatus. Lysosomes contain chemicals that break down materials such as food and old cell parts.

The cell membrane is a protective covering that separates the inside of a cell from its environment. Any material coming into or out of the cell must pass through this cell membrane.

Answer 3

All cells must:

1. Obtain energy - either by creating it themselves (autotrophs) or finding a source of energy in nature (heterotrophs)
2. Reproduce - sexually or asexually
3. Grow and develop
4. Respond to stimuli
5. Move - plants do "move" - they grow in response to tropisms and other stimuli
6. Respiration - the main ATP producer of living things - either aerobic or anaerobic
7. Excretion - the removal of toxic wastes from the cell

Answer 4

- take in food (photosynthesis)

-reproduce (DNA)

-protection

-dispose waste

-make parts of yourself

Answer 5
