Chlorophyll is present in specialised cells within plants and many algae‚ when sunlight is present‚ chlorophyll combines it with water and carbon dioxide and creates energy through photosynthesis‚ a bi-product of which is oxygen. Organism that can photosynthesise are called autotrophs or “self-feeders”. Chlorophyll in leaves enables plants to trap light energy; it traps sunlight energy for the plants and begins the process of photosynthesis. It gives plants the greenish colour

Another significant benefit of sun rays is that it makes bones stronger as sunlight gives the body Calcium necessary for enhancing bone structure. It can also get rid of bacteria and germs. It also makes the body system immune from diseases. Just some 15 minutes in the morning sunlight can give such health benefits. Spending time in the sun can also help prevent leukemia and also skin cancer. Vitamin D is essential to fight

As we age‚ our bodies make less Melatonin‚ but taking a walk in the sunlight can help to replete the supply and help an older person sleep better at night.

The goal of this lab is to determine the effects of different approaches of growing seedlings and to understand these effects. Hypothesis I believe that actual sunlight will benefit the plants in helping to make them grow. I also believe that the effect of having no light on growing seedlings will cause the plant

In the Alaskan Tundra‚ abiotic factors include wind‚ temperature‚ and sunlight. Abiotic factors are nonliving things that influence or affect the ecosystem and the organisms in it. Factors such as wind‚ temperature‚ and sunlight can have a lasting effect on an ecosystem such as an Arctic Tundra. In the Alaskan Tundra‚ strong and persistent winds rush through the air. These winds desiccate and abrade plant tissues‚ contributing to one of the many factors of why tundras aren’t able to grow trees.

The transparency of water is important to life because it allows organisms living in water to absorb the sunlight and carry out photosynthesis. If water was opaque‚ the sunlight wouldn’t be able to enter. Because they wouldn’t be able to conduct photosynthesis‚ plants would be unable to grow underwater.
