Plant cells

5. The middle layer of a leaf where all the food-making happens.
6. A plant with seeds in cones, not flowers or fruits.
7. A bunch of similar cells working together for one purpose.
8. Plants without those pipes, like moss.
12. Mesophyll: The lower layer of the leaf with big air pockets for gas exchange.
15. Plants that flower and keep their seeds inside a fruit.
16. A living thing that has to eat other stuff to get energy.
17. A waxy coat on leaves that keeps water from escaping.
18. Tiny pores, mostly under leaves, for breathing and sweating.
19. Epidermis: The bottom layer of the leaf, where you find all the stomata.
20. Mesophyll: The packed-together cells right under the leaf's skin that do a lot of the work.
22. The tiny transport tubes in a leaf for moving water and nutrients around.

1. That green stuff in plants that grabs energy from the sun.
2. Equation: The recipe for photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
3. Cells: Two cells that open and close the stomata, like a gatekeeper.
4. Plants use sunlight to make their own food from water and carbon dioxide.
9. A simple, nonvascular plant that uses spores instead of seeds.
10. The tiny green factories inside plant cells where photosynthesis happens.
11. An organism that makes its own grub, like a plant.
13. Plants with special pipes for moving water and food.
14. Epidermis: The top, clear skin of a leaf, it's just for protection.
21. Spaces: The gaps in a leaf's spongey layer for gas to float around.
