Cells!

2. Minute hairlike organelles, identical in structure to flagella, that line the surfaces of certain cells and beat in rhythmic waves
6. The process in cell division by which the nucleus divides
9. A cell organelle that makes other substances that the cell needs, such as lipids (fats) and carbohydrates (sugars)
11. The powerhouse of the cell
13. The nucleus and organelles bounded by a very flexible membrane
14. The organelle in cells that stores DNA and helps the cell make proteins
16. A thin biological layer that contains the cytoplasm and all organelles of the cell
18. The cell's digestive system
19. An organelle that modifies, packages and sorts proteins sent from the endoplasmic reticulum
20. The basic principle of modern biology
21. Makes ribosomes for the cell
22. Cells with membrane-bound organelles and a nucleus

1. An organelle in plant cells used to store food and water
3. The main food producer for plant cells
4. Cells without membrane-bound organelles or a nucleus
5. The nucleus and organelles bounded by a thick and rigid cell wall
7. The double membrane layer that separates the contents of the nucleus from the rest of the cell
8. The main protection barrier that surrounds a plant cell
10. Tiny molecules in cells that help the cell make proteins
12. A cell organelle that contains many ribosomes on its outer surface and makes proteins the cell needs
15. The material contained within the nucleus of a cell
17. The jelly-like liquid that fills the inside of a cell
