Seeds can grow without soil but the plant doesn’t get the nutrients it needs from the soil.
No Sunlight
The no sunlight plant is unhealthy but it is growing really tall. If you are wondering why the plant is getting really tall? The answer is because it wants to get to find sunlight. If you want to compare the no sunlight to the controlled lima bean they are about the same height. The different part is that the no sunlight is not as healthy. To me I think the no sunlight plant is doing in the middle because it is getting carbon dioxide but it’s not getting the sunlight for photosynthesis.
No Air
My no air plant is not good at all. The no air didn’t grow because the plant needs carbon dioxide to breathe and it did not get carbon dioxide. If you were going to compare the no air to the controlled ,the controlled is better because it has leaves and the top of the plant is coming out of the bag. To me I think the no air is doing the worst because it’s not getting the carbon dioxide for photosynthesis, but it is still getting the sunlight it needs.
Controlled
My controlled plant is doing good. It’s getting the carbon dioxide and the sunlight the plant needs. It grew roots then root hairs then the stem then the leaves. To me the controlled plant is doing the best because it’s not unhealthy like the no sunlight or it’s not like the no air and it’s not getting carbon dioxide that’s why I think the controlled plant is doing the best.
Lifecycle
As the plant started to grow it changed first it grew roots then the root hairs then the stem and then it started to grow leaves and now it’s a plant. In other words it was a seed then a seedling then a young plant then the final stage a mature plant.
