Lab Bio Ch. 3 Organelle Flashcard

Front

What are vacuoles?

Back

Vacuoles are storage units of cells that contain water, salts, carbohydrates, proteins, and other substances. Plants have very large vacuoles.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what can enter and exit the cell, maintaining the internal environment.

Front

What is the endoplasmic reticulum?

Back

The endoplasmic reticulum acts like a conveyor belt, moving proteins out of the cell. There are two types: rough (with ribosomes) and smooth (without ribosomes).

Front

What are lysosomes?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste products in the cell, functioning like a cleanup crew.

Front

What are cilia and flagella?

Back

Cilia and flagella are part of the cytoskeleton that assist in attachment and movement. They appear as tiny hairs or a long tail.

Front

What is the role of the nucleus in a cell?

Back

The nucleus is the control center of the cell, containing genetic material (DNA) and regulating cell activities.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis in the cell, translating messenger RNA into proteins.

Front

What is the golgi apparatus?

Back

The golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the cytoskeleton?

Back

The cytoskeleton is a network of fibers that provides structural support, shape, and facilitates movement within the cell.

Front

What are vesicles?

Back

Vesicles are small membrane-bound sacs that transport materials within the cell and to the cell membrane for secretion.
