Question

During photosynthesis, different gases move in and out of plant cells. Which phrase best represents the net flow of

Answer 1

The last one because plants move oxygen out to the atmosphere while taking in C02

Answer 2

Answer:

$\boxed {\tt D. \ Carbon \ dioxide \ moves \ in \ and \ oxygen \ moves \ out}$

Explanation:

Remember, photosynthesis is a process certain organisms, like plants and algae, undergo to make glucose. The photosynthesis formula is:

6H₂O + 6CO₂ + energy ⇒ C₆H₁₂O₆ + 6O₂

Water, carbon dioxide, and light energy from the sun become glucose/sugar and oxygen.

The plant uses the carbon dioxide in the process, so that gas moves in. Oxygen isn't used by the organism and is considered a waste product. That gas moves out.

Therefore, the best answer is D. carbon dioxide moves in and oxygen moves out
