Plant cells

1. The top, clear skin of a leaf, it's just for protection.
5. Plants with special pipes for moving water and food.
7. Plants that flower and keep their seeds inside a fruit.
8. A bunch of similar cells working together for one purpose.
10. The packed-together cells right under the leaf's skin that do a lot of the work.
11. A waxy coat on leaves that keeps water from escaping.
12. The bottom layer of the leaf, where you find all the stomata.
15. That green stuff in plants that grabs energy from the sun.
16. A plant with seeds in cones, not flowers or fruits.
17. Plants use sunlight to make their own food from water and carbon dioxide. Pretty cool, right?
19. The gaps in a leaf's spongey layer for gas to float around.
21. Plants without those pipes, like moss.

2. A simple, nonvascular plant that uses spores instead of seeds.
3. Tiny pores, mostly under leaves, for breathing and sweating.
4. Two cells that open and close the stomata, like a gatekeeper.
5. The tiny transport tubes in a leaf for moving water and nutrients around.
6. An organism that makes its own grub, like a plant.
9. A living thing that has to eat other stuff to get energy.
13. The lower layer of the leaf with big air pockets for gas exchange.
14. Equation: The recipe for photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
18. The middle layer of a leaf where all the food-making happens.
20. The tiny green factories inside plant cells where photosynthesis happens.
