Read the passage below and then indicate whether the following statements are true or false.

Photosynthesis: The Process of Making Food

Photosynthesis is a critical process that occurs in the chloroplasts of plant cells. It involves the conversion of light energy into chemical energy, which is stored as glucose (a type of sugar). The process requires several key components: light, carbon dioxide, water, and chlorophyll. Chlorophyll, the green pigment in plants, captures light energy from the sun. This energy is then used to convert carbon dioxide, absorbed from the air, and water, absorbed from the soil, into glucose. Oxygen is released as a byproduct and is essential for the survival of most living organisms.

True False
In photosynthesis, carbon dioxide and water are converted into oxygen.

Oxygen is the gas used by plants as a reactant during photosynthesis.

During photosynthesis, oxygen is released as a byproduct.

The primary purpose of photosynthesis is to produce glucose.

Chlorophyll absorbs light energy from the sun.

Oxygen is the byproduct of photosynthesis that is essential for human survival.

1 answer

Here are the answers to whether the statements are true or false based on the passage provided:

  1. In photosynthesis, carbon dioxide and water are converted into oxygen.
    False (While oxygen is released, carbon dioxide and water are primarily converted into glucose. Oxygen is a byproduct.)

  2. Oxygen is the gas used by plants as a reactant during photosynthesis.
    False (Oxygen is not used in photosynthesis; it is produced as a byproduct. The reactants are carbon dioxide and water.)

  3. During photosynthesis, oxygen is released as a byproduct.
    True (The passage states that oxygen is released as a byproduct of the process.)

  4. The primary purpose of photosynthesis is to produce glucose.
    True (The passage mentions that photosynthesis involves converting light energy into chemical energy stored as glucose.)

  5. Chlorophyll absorbs light energy from the sun.
    True (The passage clearly states that chlorophyll captures light energy from the sun.)

  6. Oxygen is the byproduct of photosynthesis that is essential for human survival.
    True (The passage indicates that oxygen is essential for the survival of most living organisms, including humans.)

Question 2

Without a diagram provided, I cannot label the diagram of photosynthesis. However, you can categorize the components as follows:

  • Drop Target 1: Reactants - Carbon Dioxide (CO2) and Water (H2O)
  • Drop Target 2: Products - Glucose (C6H12O6) and Oxygen (O2)
  • Drop Target 3: Location - Chloroplasts (where photosynthesis occurs)
  • Drop Target 4: Light Energy from the Sun (which is used in the process)
  • Drop Target 5: Chlorophyll (the pigment that captures light energy)

Question 3

Here is the general equation for photosynthesis along with the chemical names:

  • Drop Target 1: 6CO2 (Carbon Dioxide)
  • Drop Target 2: 6H2O (Water)
  • Drop Target 3: C6H12O6 (Glucose)
  • Drop Target 4: 6O2 (Oxygen)

Feel free to update these with your specific diagram and labels if needed!
