Exercise Project

Watch this video of natural phenomenon: Aurora Borealis.

Photosynthesis occurs in green plants; to be specific it occurs in green leaves. The word photosynthesis means putting together with light. Green plants use energy from light to combine carbon dioxide and water to make sugar and other chemical compounds which is needed by the consumer. Animals and men are their consumers.

The light is absorbed by a green pigment called chlorophyll of the leaves. Each food-making cell in a leaf contains chlorophyll in small bodies called chloroplasts. In chloroplasts, light energy causes water to be drawn from the soil, to split into hydrogen and oxygen.

Photosynthesis

Afterwards, the hydrogen combines with carbon dioxide from the air, forming a simple sugar. Oxygen from the water molecules is given off in the process. From the sugar—together with nitrogen, sulphur, and phosphorus from the soil—green plants can make starch, fat, protein, vitamins and other complex compounds which are valuable for human life.

Character Building

Use Glass Whenever PossibleStoring your food in glass is an eco-friendly and healthier alternative to plastic. Plastics contain harmful chemicals which leach into our bodies, our water supplies, and the soil. There are huge islands of plastic floating around both the Pacific and Atlantic oceans. The Great Pacific Garbage Patch, composed of plastics, chemical sludge, and other debris has grown to be twice the size of Texas!
