Lesson 12 ·Class 9 · Cell : The Unit of Life · Match Lab
Life Activities Are Cellular
Every body process traces back to a cell.
Match each activity of the whole body to the cell structure that actually performs it.

Free play — tap an item on the left, then its partner on the right; each link tells you why. Switch to when you're ready to test yourself.
Nothing the body does is separate from what its cells do — this is the point of the cell theory.
What this lesson covers
Challenges to clear
- Trace every activity to its structure.
- Connect getting rid of cell waste to the parts that handle it.
The task
Match each activity of the whole body to the cell structure that actually performs it.
What this lesson covers
- Releasing energy from food — Mitochondria (Every bit of usable energy in the body is made here.)
- Building the body's proteins — Ribosomes (Growth and repair are protein synthesis at the cell level.)
- Passing characters to offspring — Chromosomes in the nucleus (Inheritance is DNA being copied and passed on.)
- Making food from sunlight — Chloroplasts (All the food in every food chain starts here.)
- Getting rid of cell waste — Lysosomes and the cell membrane (Digestion of waste, then transport out across the membrane.)
- Controlling what enters and leaves — Cell membrane (Selective permeability is the cell deciding what to admit.)
Hint
Nothing the body does is separate from what its cells do — this is the point of the cell theory.
