The process of the seed is to create the plant and to make the roots.
To germinate means to begin growing or sprouting.
The embryo begins growing roots and pushes down downward into the ground. The top half top of the embryo will begin to grow leaves and push up through the soil; to reach the surface of the ground the seed is now a seedling, or a baby plant. the leaves use this gas [carbon dioxide] that is found in the air to make their own food.
photosynthesis is when cells bright in gas and turn it into sugar the plant uses the sugar to feed the plant.
the seedling will grow into a young plant and then into a young adult plant.
over time the plant will grow into an adult/mature plant. this means that the plan is fully grown and is now old enough to reproduce.
