Sofia is studying how different conditions affect photosynthesis in plants. In one experiment, she placed a plant in a dark closet and left it there for a week. Over time, the leaves turned yellow and began to wilt. Eventually, the plant died. What most likely caused the plant to die?

• The plant lacked the sunlight it needed for photosynthesis.

• The plant could not absorb minerals through its leaves.

• The plant's roots stopped producing chlorophyll (green pigment).

• The plant produced too much oxygen during photosynthesis.

Isabella wanted to see what would happen if a plant could not get air. In her experiment, she covered the entire plant tightly with clear plastic wrap, sealing it around the pot so no air could get in. After several days, the leaves turned brown and the plant died. What most likely caused the plant to die?

• The plant could not soak up enough sunlight needed for photosynthesis.

• The plant could not get the oxygen it needed for photosynthesis.

• The plant’s roots stopped taking in water from the soil.

• The plant made too much sugar and could not use it all.
