Cause and effect: flowers


by Christina

This is a cause and effect paragraph essay on flowers, and their connection to the sun. when you study the flower while blocking the sun or any other light you can see the way the plant reacts without light, which could give a description of why the plant needs light.
If we started out with a tiny flower, and suppose a person came and accidentally dropped a pan over the flower without noticing, it would start the cause and effect. The flower would be blocked from the sun, but the water and the nutrients in the soil would still feed the flower. The plant will have healthy nutrients, too. But a flower cannot live by those alone.

The sun gives the plants chlorophyll, a chemical that keeps the plants green. The chemical is also a nutrient that the plants need, but not one that can be given through the soil. If the sun is blocked from reaching the flower, the plant gets no chlorophyll, the green starts to fade, and it gets sick. If a plant is sick for another reason, it will also lose chlorophyll, and become dry and yellow.

There are many bees that feed from the flower, and when it dies, a little of the bees food source dies down. But supposing it were a huge field of flowers that were blocked from light, it could cause some damage. However, the flower fades into compost, and when the pan is removed and new seeds are blown into the soil, the plants grow easier.

So ends our cause and effect. By the man dropping the pan over the flower, the sun couldn't reach the flower, and the flower got sick and died, and the flower turned into compost so when the pan was removed the seeds could be planted in the compost, and the compost would make the plant healthier. So it was actually for a good cause.
