About this biology word search
- The cell is the basic unit of life, and scientists estimate the human body contains roughly 37 trillion of them.
- Mitochondria release energy from food for the cell, which is why they are often called the powerhouse of the cell.
- Plants make their own food through photosynthesis, using sunlight, water and carbon dioxide and releasing oxygen.
- Study tip: build a quick food chain from the puzzle words, starting with a producer and ending with a decomposer.
