Cells and Microscopes.

2. Storage space in plant cells.
4. The basic unit of all life. All organisms are made of cells.
7. Small parts in the cytoplasm of all cells, where respiration occurs.
11. The object you look at using a microscope.
13. A process in which organisms make more organisms like themselves. All organisms reproduce.
17. Tough wall around plant cells. Helps to support the cell.
21. Cell surface that controls what goes into and out of a cell.
22. The ‘control centre’ of a cell.
23. Part of a microscope. You put a slide on it.
24. How much bigger a microscope makes something appear.
25. A process in which substances release energy for an organism to use. All organisms respire. There are, however, different forms of respiration.

1. Green substance found inside chloroplasts.
3. A living thing.
5. Getting rid of waste. All organisms excrete.
6. To make an image clear and sharp. If an image is ‘in focus’ it is clear and sharp.
7. Going from place to place. All organisms can move themselves or parts of themselves.
8. Green discs containing chlorophyll. Found in plant cells. Where the plant makes food using photosynthesis.
9. Focusing wheel on a microscope that moves parts of the microscope a small amount to bring the image into focus.
10. Part of the microscope you look down.
12. Substances that help organisms respire and grow.All organisms need nutrition.
14. Focusing wheel on a microscope that moves parts of the microscope a large amount to get the image into focus.
15. Thin piece of glass used to hold a specimen in place on a slide. It also keeps the specimen flat and stops it drying out.
16. The ability to detect things in the surroundings.All organisms can sense certain changes in their surroundings.
18. Watery jelly inside a cell where the cell’s activitiestake place.
19. Glass sheet that a specimen is put on.
20. Increase in size. All organisms grow.
