Seeds turned into seedlings PPT, part 2: our thoughts

Think about the following questions and discuss them.

Seeds turn into seedlings PPT, part three: leaves provide "food" for plants

After years of research, scientists have discovered that most plants can produce their own "food" - nutrients to meet the needs of plant growth. These nutrients are produced by the plant's green leaves using carbon dioxide and water using energy provided by sunlight.

Collecting information about photosynthesis can help us further understand that the green leaves of plants create the "food" - nutrients needed for plant growth.

In 1771, British scientist Priestley discovered that green plants could renew the air. Later, experiments proved that this was the result of oxygen released by plant photosynthesis. Chloroplasts in green plants use light to convert carbon dioxide and water into nutrients and release oxygen.
