It does not seem to move, to grow, nor do anything. In fact, even with biochemical tests for the metabolic processes we associate with life (respiration, etc.) the rate of these processes is so slow that it would be difficult to determine whether there really was anything alive in a seed. .
Seeds initially germinate when they absorb water, bursting the seed coat. Heat and light energy necessary for the process of germination. Some plants rely more on heat, others more on light. Heat and light energy starts chemical reactions in embryo. This chemical energy stored as starch in the seed, is changed to sugar for use during germination. The development of the plant embryo is controlled by hormones as well and a plant can be artificially made to germinate by treating it with the correct hormones. Germination, involves the bringing together of essential chemicals, hydrogen and oxygen, to generate energy that will be directed toward expanding and propelling the two growing points of the germinating seed outward (upward and downward if guided properly).
After a formation of an embryo plant convert solar energy into stored chemical energy. Photosynthesis is the process of converting solar energy, water, and carbon dioxide into carbohydrates and oxygen. The process occurs in two steps: first light energy is absorbed by chlorophyll to split a molecule of water releasing hydrogen and oxygen. The second step uses the energy to convert carbon dioxide to carbohydrates.

6CO2+12H2O ---> C6H12O6+6O2+6H2O.
(Chlorophyll).
The carbohydrate (C6H12O6+6O2) can be converted into starch and stored by the plant. Carbohydrate can be combined with other sugar molecules to make cellulose, the basic structural material of a plant.
As solar radiation increase the rate of photosynthesis increases. For many plants there is an upper limit to the rate of photosynthesis.
Sibilla Merian, a German naturalist, author, and illustrator was born in Germany. Frankfurt was a small town in Germany where she was raised. They had a wide family that were either an engraver and or a publisher. After the death of her stepfather that taught her much botony and engraving, she was l...
Throughout the United States there are many major environmental disturbances that effect the way trees maintain their ability to live. One major disturbance that effects the way trees grow are ice storms. Ice storms can be deadly for many trees but trees also can not be damaged at all because they become resistant to the ice. Almost every year there has been an ice storm that effects part of the northern and eastern United States effecting not only the people that live in that county but also the population of tree species within a forest community. Throughout the years scientists have bee...
