Problem/ Question: How does sunlight affect the growth of plant?
Data & information:
Plants need sunlight. Houseplants lean toward the Sun, and if they do not get enough light they wither anddie. Plants use sunlight to make their food. This process is called photosynthesis.
Photosynthesis is a scientific word made up from Greek words. These words mean “putting things together usinglight.”
Inside plants’ leaves, light causes air and water to combine to make new chemicals. These chemicals are food for the plants.
In most plants, photosynthesis takes place mainly in the leaves. Likeother living things, plants are made up of tiny cells. The cells in a plant’s leaves contain even smaller, disc-shaped parts called chloroplasts. Chloroplasts are the food factories where photosynthesishappens. A leaf the size of your little fingernail contains more than 10 million of them.
Chloroplasts contain chemical called chlorophyll, which is bright green. Chlorophyll gives plants their greencolor and makes photosynthesis work.
For photosynthesis to work, the chloroplasts need to collect three ingredients: sunlight, air, and water. Sunlight shines on the leaf, and the green chlorophyllinside the chloroplasts soaks it up. Air enters the leaf through tiny holes in the leaf’s surface, called stomata. Water is sucked from the ground by the plant’s roots. It travels through tubes in thestem or trunk to the leaves.
When all three ingredients are present inside the chloroplasts, a chemical reaction takes place. The reaction takes place between a gas in air called carbon dioxide andhydrogen, a part of water. Sunlight causes these two to combine and make new chemicals called carbohydrates. Carbohydrates are plant food. Plants use these chemicals to live and grow.

Hypothesis: 1.Without the use of sunlight carbohydrates cannot be formed, thus, the reaction would not be complete and...
