2. The cell component where respiration takes place.
3. The cell component that controls which substances can move into and out of the cell.
11. A cell whose shape and structure enable it to perform a particular function.
12. The plant cell component where photosynthesis takes place.
14. When a unicellular organism splits itself into two identical cells.
16. The cell component that controls the cell and contains genetic material.
19. A unicellular organism.

7. Unicellular organism that performs photosynthesis.
8. Consisting of just one cell.
9. The structure and features of a cell that make it suited to carrying out a particular job.
10. An optical instrument used to magnify objects, so small details can be seen clearly.
13. Carefully looking at an object or process.
15. A tail-like structure that allows euglenas to move.
17. A cell containing male genetic material.
18. An animal cell that transmits electrical impulses around the body.
