2. Living things that have to eat other organisms for food and do not have cell walls
3. Very small, single-celled organisms that do not have a nucleus
6. The parts inside plant cells that trap light so the plant can make food
7. When a living thing changes its position or moves from one place to another
11. How living things notice and react to changes in the world around them
12. The tiny, thread-like structures that make up the body of a fungus
13. When a living thing gets bigger in size or increases its number of cells
15. Getting or making food to give the body energy and nutrients
17. A serious lung illness that can be caused by a type of bacteria called Pneumococcus
18. Keeping things inside the body steady, like keeping a constant body temperature
19. Getting rid of toxic waste products that the body has made
20. Living things that make their own food by photosynthesis and have cell walls made of cellulose
