Let's check your sentences carefully and make sure they are clear and correct.
Your original sentences are: "Long roots help plants find water and pointy needles are better at saving water than leaves."
These sentences are mostly correct, but it is better to add a comma to separate the two ideas for clarity:
"Long roots help plants find water, and pointy needles are better at saving water than leaves."
Here’s why:
- The comma before and shows that there are two separate ideas.
- It helps readers understand that there are two facts: first about roots, and second about needles.
Great job! Your sentences are now both grammatically correct and easy to understand.
