Photosynthesis Is The Process Where

The equation below shows the process of photosynthesis.

Carbon dioxide + Water → ? + Oxygen

What forms of energy are entering and exiting this process?

• Chemical energy is entering, and light energy is exiting.

• Wind energy is entering, and light energy is exiting.

• Light energy is entering, and chemical energy is exiting.

• Thermal energy is entering, and electrical energy is exiting.

he picture shows a leaf found on an autotrophic plant.

The cells in this leaf are making their own energy by the process of

• respiration, where oxygen and sunlight at Q and R are taken in and then converted into carbon dioxide and glucose at

  S and T.

• photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and

  oxygen at S and T

• photosynthesis, where glucose and oxygen at Q and R are taken in and then converted into water vapor and thermal

  energy at S and T.

• respiration, where carbon dioxide and oxygen at Q and R are taken in and then converted into thermal energy and

  methane gas at S and T.

Leaves of green plants contain openings known as stomata. These are opened and closed by specialized cells that allow

gases to be exchanged between the leaf and the outside environment.

Which of the following best describes the flow of gases into and out of a leaf through stomata on a sunny day?

• Carbon dioxide moves in; oxygen moves out.

• Carbon dioxide and oxygen move in; ozone moves out.

• Water vapor and ozone move in; carbon dioxide moves out.

• Oxygen moves in; nitrogen moves out.
