The plants grew in their cups for 10 days before they were measured. 
Plant growing condition
Height after 10 days (mm)
Normal
50mm 
Green cellophane
0 
Red cellophane
0
Overwater
50mm
The normal seedling was planted in normal potting mix and grew to a height of _________mm.
The green cellophane seedling was planted in normal potting mix, covered in green cellophane and watered. It grew to a height of ________mm. The red cellophane seedling was planted in normal potting mix............. to a height of ___________mm. The overwatered seedling was planted in normal potting mix, the water could not drain out the bottom of the pot and it grew to a height of ______mm
Conclusion:
From the pictures and evidence, we can conclude that:
The seedling height was:
1.
2.
3.
4.
The best growing conditions were:
1. normal
2.
3.
4.
therefore the seedling with _____________ conditions grew to a height of _________mm.
