Front

What is a vacuole?

Back

A vacuole is a storage organelle in a cell that holds nutrients, water, and waste.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them in a vesicle.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles that fuse with the cell membrane.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions.

Front

What is the function of the Golgi body?

Back

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