: Read the paragraphs below and complete the flow chart with the statement or statements that correspond to the steps of scientific investigation. Refer to the given illustration.
How does sunlight affect the growth of a plant? In most plants, photosynthesis takes place mainly in the leaves. For photosynthesis to work, the chloroplast needs a source of energy like sunlight and ingredients such as carbon dioxide and water. When light energy, carbon dioxide, and water are present, a chemical reaction takes place.
Two different set-ups were prepared, Plant A and Plant B. Plant A was placed inside the box, hence, there is no air and sunlight. Plant B was placed outside the house with enough sunlight. After a week, the effect of sunlight on the growth and development of the plants was observed. Plant A, which is placed inside the box withered and died. While plant B with enough sunlight grew healthy.
Therefore, it only proves that sunlight and a gas in the air has a great effect on the growth of a plant. Without sunlight and a gas from the air, plants can’t live nor grow to the fullest.
