Q:

What do plants eat?

A:

Plants make their own food through a process known as photosynthesis, which involves creating energy from sunlight, water, carbon dioxide and other nutrients. The substance in plants that makes the energy is known as chlorophyll, which is located in the leaves and is what gives plants their green color.

Chlorophyll is responsible for turning the necessary ingredients into carbohydrates that the plant can then consume for energy. This process takes place within a structure known as a chloroplast. The necessary carbon dioxide is taken in through small holes on the leaf known as stomata, which also release oxygen during the process.

For photosynthesis to happen, six molecules of carbon dioxide and six molecules of water join together in a chemical reaction when stimulated by light energy. The reaction of the two compounds results in the formation of C6H12O6, a complex sugar, and six molecules of 02 or oxygen gas. This resulting oxygen gas is the primary source of oxygen that humans and other animals breathe, meaning animal life could not exist without plants producing oxygen through photosynthesis.

The sugar that is formed through photosynthesis is stored in a chemical known as adenosine triphosphate or ATP, which has a very similar chemical makeup to the DNA found in animals.

  • Q:

    What is photosynthesis?

    A:

    Photosynthesis is the process by which green plants manufacture their own food. The process takes place in small structures within the plant’s cells called chloroplasts. Photosynthesis evolved about 3 billion years ago, yet it remains the most important method for harvesting the sun’s energy on the planet.

    How do plants make oxygen?

    A:

    Plants make oxygen by using light energy to convert water and carbon dioxide into sugar and oxygen molecules. This occurs during the process of photosynthesis.

    How do you revive a dead plant?

    A:

    To revive a dead plant, cut the stems back, and reduce the sunlight and water intake of the plant. Wait between three weeks to two months for new leaves or stems to appear.

  • Q:

    How does sunlight affect plant growth?

    A:

    Plants are dependent upon sunlight to fuel their organic activities; insufficient sunlight stunts or prevents plant growth, while overexposure to sunlight is harmful. Plants react to changing daylight patterns to prepare themselves for seasonal changes. Many plants flower in response to specific durations of sunlight and darkness.
