[Audio] Photosynthesis second grade lesson How Plants make their own food? Photosynthesis Second Grade lesson.

[Audio] You may have heard, it's said that plants produce their own food, but have you ever wondered how?.

[Audio] The answer is the process is called photosynthesis. The word photosynthesis is comprised of two parts: photo, meaning light, and synthesis, meaning put together. ..

[Audio] Through photosynthesis, plants convert energy from sunlight into chemical energy. Plants utilize chemical energy to fuel activities such as growth and seed production..

[Audio] In order to perform photosynthesis plants require three basic elements : sunlight, water and carbon dioxide. Plants convert these components into starches and sugars, releasing oxygen..

[Audio] Now that you are familiar with the concept of photosynthesis, let's examine the process in greater detail. The plant absorbs sunlight and water. The process occurs in the leaves and other green parts of the plant, and it is facilitated by specialized structures known as chloroplasts. Chloroplasts contain Chlorophyll. The chlorophyll absorbs the energy from the sunlight and give the plant the green color..

[Audio] Plants also takes in carbon dioxide from the air: plants need fresh air to grow. They rely on carbon dioxide..

[Audio] Finally, the plant takes in the water and other nutrients from the soil typically through its roots: this water travels up the stem of the plant to the leaves where it's used in photosynthesis..
