Read the following passage. This is an exercise in careful reading, so make sure to read the passage carefully.

Question

Plants perform photosynthesis in order to rearrange atoms from carbon dioxide and water to form glucose and oxygen gas. Because the glucose can be used as a food source for the plants, plants are known as autotrophs. The reaction that occurs in photosynthesis is represented by this equation: 6CO2 + 6H2O →C6H12O6 + 6O2. Photosynthesis occurs in specialized organelles, called chloroplasts, in the cells of green plants.

Here is the same passage, but it has the sentences numbered this time.

Sentences
tell us that plant cells take in
and
, which are the
used during photosynthesis.

Sentence
tells us that plants are
, which means they make their own food.​​​​​​​

Answer 1

To complete the sentences correctly, we can refer to the information provided in the passage.

1. The first part of the first sentence requires two things that plant cells take in for photosynthesis, which are carbon dioxide and water.
2. The second part of the first sentence implies that these components are the reactants used during photosynthesis.
3. The second sentence should identify what plants are known as, indicating that plants are autotrophs.

Using this information, the completed sentences would be:

Sentences 1 and 3 tell us that plant cells take in carbon dioxide and water, which are the reactants used during photosynthesis.

Sentence 2 tells us that plants are autotrophs, which means they make their own food.
