Cell Organelles

Complete each sentence or statement.

All cells are surrounded by a _____ ___________.

The _____ __________ acts as a barrier between the inside of the cell and the cell's environment.

The ____ ___________ controls the passage of materials in or out of the cell.

What structure allows cells to take in nutrients and dispose of waste.

_____________ are structures inside the cell that maintain the life of the cell.

A fluid known as _____________ surrounds the organelles of the cell.

Many organisms have cells that contain a large organelle, called a ___________, near the center of the cell.

Why is the nucleus referred to as the control center of the cell?

A cell's genetic information is contained within structures called _________________.

The nucleus is surrounded by a thin membrane called the _______ ____________.

Chemical reactions occur in the ________________ that transfer energy from organic compounds to ATP.

Small, round organelles called ________________ are where amino acids are linked together to form proteins.

The _______________ ________________ is a system of folds and channels that is responsible for transporting materials throughout the cell.

Some endoplasmic reticulum (ER) are covered by _________________.

The ____________ formed in the ribosomes pass into the ER, where they are transported for use elsewhere.

The _____ ____________ is responsible for transporting proteins and other materials.

The _________ _______________ modifies materials for different functions, encloses them in a piece of its membrane, and then pinches them off to form small compartments. The compartments then transport their contents to other parts of the cell or outside the cell.

_______________ are small sac-like organelles that contain enzymes. These enzymes might digest, or break down, proteins, carbohydrates, lipids, and nucleic acids. They might also destroy worn-out or damaged organelles, rid wastes, and protect the cell from foreign invaders.

_______ ______ are linked together at ribosomes.

Materials that enter into a cell must pass through the _____ ________________.

______________ are located in the nucleus.

Keeping in mind the information covered by the above questions, review the following diagram of a typical eukaryotic cell. How does this eukaryotic cell differ from a prokaryotic cell?

Look at the following diagram of a typical plant cell. How does it differ from the typical animal cell shown in the previous question?

The table below will help you remember the differences among prokaryotes, plant cells, and animal cells. Memorize this and you'll be in great shape.
