Abstract Pea plants, along with many other plants and vegetables, are taken for granted. Without them, much of the world would be

It is important for seeds to be able to be dormant because that they can be saved and planted at a later time. Dormant seeds are only able to be planted because of germination which “wakes up” or activates the seeds. If seeds could not be germinated, then dormant seeds could not be planted which would mean less crops and flowers which would effect in a negative way. Many animals would die because crops and also flowers are near the bottom of the food chain and are necessary in life for almost all living things, even if an animal is a carnivore. Germination is not the only thing necessary for plants’ growth. Plants need water, nutrients, carbon dioxide, warmth and a source of light. Light is a key part of photosynthesis and without it, a plant would not be able to produce food for itself and it would eventually die. Germination and light are necessary in plant growth, and plants are necessary for all living things. Hypothesis As the growth a pea plant is exposed to different colors of light (red and green), the plant’s growth will be better in the red light.

Variables & Groups Experimental groups: Color of light (red, green, and standard light bulb) Dependent Variable: The growth of the plants affected Control Variables: The plant getting light form the non-colored, standard light bulb. Extraneous Variables: Depth of the pea, amount of water, temperature of water, length of soaking, and light
