Water will move out - a condition called fertilizer burn . In dicots, the stem develops, forming an arch that pulls the tip of the stem out of the soil. In dicots the cotyledons, or seed leaves, will open up and begin photosynthesizing. The seed coat is hard and the protoplasm is condensed. As the temperature warms up, most cellular processes speed up.
Respiration is a chemical process which occurs within every living cell in every living organism.
The energy is used to fuel growth and other metabolic processes. Oxygen is required for respiration and carbon dioxide is released as a by-product. If these seeds are planted deep in the soil, they would not have enough energy to grow to the surface. A period of active growth when energy from photosynthesis goes toward the development of stems, roots and leaves. Photosynthesis is a chemical process that uses carbon dioxide, water and light energy to produce a simple sugar, glucose.
