Cell Functions
Grade 6 · Science · Cells and Organisms · South Carolina, USA
Lesson Summary
Each part of a cell has a specific job, from the nucleus that controls activities to the mitochondria that produce energy.
Explanation
The nucleus is the control center of the cell, containing DNA that directs the cell's activities. The cell membrane controls what enters and leaves the cell. Mitochondria are the powerhouses that convert food into energy the cell can use. The endoplasmic reticulum and ribosomes work together to build proteins. Vacuoles store water, nutrients, and waste. Each organelle plays a specific role, and together they keep the cell alive and functioning, much like the different parts of a factory working together.
