This is where my whole life began- as one individual little seed found inside a tomato fruit. Small seeds allow for quicker ripening and sooner dispersal. My job as a seed is to protect, nourish and dormant the embryo under unfavorable conditions. I am typically white and moist in the shape similar to a teardrop or an oval. I have a little baby tomato plant inside of me, known as an embryo, just waiting to mature into a flowering plant. This embryo is surrounded by stored food from my parent plant and encased with my protective seed coat. The seed coat protects the embryo from predation and keeps it from drying out. The stored food is utilized to keep the embryo alive, while I undergo dormancy. In dormancy, I remain inactive until the environment conditions are best suitable for the embryo to begin growth. Once the environment is suitable, I begin to absorb water, swell up and the embryo inside me begins to develop. This process is known as germination. Once I began germination, I split apart my seed and began to build my roots. My roots are long, thin structures that spread out below the ground to assist in keeping my developing plant alive, by absorbing water and minerals from the soil. There are two important structures in my roots- the rootlets, which help to anchor my developing plant in the soil, so it don’t blow away by the wind or wash away by the water; and the root hairs, which are tiny microscopic hairs that cover the rootlets and serve the function of increasing the surface area my roots cover, allowing more absorption of water and minerals. The xylem also originates in my roots. Xylems are the tubes that carry water and minerals from the soil, through my roots, up to the remainder of my developing tomato plant. Although, phloem is present in my roots and responsible for delivering synthesized food, it does not originate here. Xylem and phloem are found in every part of my flowering plant. The second organ developing from my germinating seed is my

stem. The stem helps to support the leaves, flowers and fruits of my developing tomato plant and connect these structures to my roots, so they have a delivery route for water, minerals and food. The delivery route, again, is through the xylem and phloem. The xylem and phloem also helps to thicken and strengthen my stems. My stems are narrow, stick-like
