Hello!
Let's go over the meanings of each term in the chart:
- A nodule is a lump or notable bump.
- Roots are used by plants to absorb nutrients from the soil.
- Plants with Rhizobium are typically larger in size.
I wish I could help you more, but I don't really have any more information on the sheet than what you provided. I didn't work on it myself, so I don't even know what it's truly for.
I hope I helped! :)
