Of all the organisms in the natural world, green plants are the only ones that manufacture their own food. This process is called photosynthesis and begins when light strikes the plant's leaves (both sunlight and artificial light can power this process). Cells in the plant's leaves, called chloroplasts, contain a green pigment called chlorophyll which interacts with sunlight to split the water

There are two basic types of reproduction of living organisms. One type, sexual reproduction, requires the union of male and female sex cells, or gametes (sperm and eggs) in the formation of a new organism. The second type is asexual reproduction in which there is no union of sex cells. In this project, you will study one kind of asexual reproduction by examining the ability of plants

The propagation of plants is a very important aspect of life due to the importance of plants. The ways in which plants can be propagated are discussed due to the time that it takes to grow a plant. The fastest and most efficient way to grow plants is wanted by all the industries that produce the plants for society. I have decided to determine the fastest way of propagation by testing how cuttings

This project was performed to determine how different concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day, the largest concentration of salt will harm the plants the most.

The following lesson can be used as a way of approaching the scientific method during or after a unit on plant growth and development. This investigative activity will enable students to explore the effects of specific plant hormones (abscisic acid and gibberellic acid) on seed germination. They will formulate a hypothesis as well as design and perform the experiment to test the hypothesis.
