What unique abilities does thyme have? Thyme is a powerful antiseptic and it destroys fungal infections. Some Scottish people use it in tea to prevent nightmares and gain courage and strength.

Parts of the plant. Thyme (thymus vulgaris) Photosynthesis happens in the chloroplasts. Flower Stem Leaves

About Thyme 1.The organic compounds are thymol and carvacrol and they work as insecticides. 2.This helps the plant survive by keeping off bugs 3.This is an adaptation because other plants are eaten by these pests and die but thyme isn’t. Thyme was used by the Romans in bathes to give themselves vigor. Now thyme is used in cooking as an herb to give more flavor, and the leaves, when dried and crumbled, are used in incense.

General Plant Information Three factors that affect plant growth are sunlight, water, and carbon dioxide.

General Plant Information 1.Photosynthesis takes carbon dioxide, sunlight, and water and turns them into plant food (sugar). 2.Plant food, or sugar is the product of photosynthesis. 3.Chloroplasts are the organelles that are responsible for photosynthesis. 4.Xylem transports water, an important part of photosynthesis, to all parts of the tree.

Project Design 1.We planted thyme seeds. 2.We put one in the dark and one in the light. 3.We charted and compared the growth of both plants.

Other Observations 1.The plant that was exposed to light grew towards it. This is called positive phototropism. The plant that was in the dark was bent over. 2.The plants’ roots grew down into the soil. This is called positive geotropism. 3.The plants in the dark grew, but they were thin and the leaves were a light yellowish green color instead of a bright healthy green like the plants exposed to light.

Conclusion Surprisingly enough, the dark plants seemed to grow taller even though they weren’t exposed to sunlight and not as healthy in appearance. Both plants grew up to 3 cm. We think that there were too many plants for them to grow healthily and get enough water and nutrients form the soil. The data refuted our hypothesis.
