Question

multiple - choice question

1. does a plant need to be in the ground with roots to make oxygen?

b. no
a. yes
c. depends on the plant

Explanation:

Plants make oxygen through photosynthesis in their leaves. Roots are for absorbing water and nutrients, not for oxygen - making. Even if a plant is not in the ground (e.g., hydroponic plants), as long as it has leaves and can carry out photosynthesis (with light, carbon dioxide, and water available), it can make oxygen.

Answer:

B. No
