What You'll Learn

Cells are the smallest units of life, and each one contains tiny structures called organelles that carry out specific jobs. The nucleus stores genetic information, the mitochondria release energy, and the cell membrane controls what enters and leaves the cell.

Key Words

Tap a word to see its definition.

Steps

Step 1 โ€” Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 โ€” Do

Step 3 โ€” Observe

Look for patterns in your observations.

Step 4 โ€” Record

Make a graph or chart showing your results.
