Transcript of The Cherry Blossom Tree

The Cherry Blossom Tree
(Prunus serrulata)

Tree Organs
Trees have three major organs roots, stems and leaves. The roots are responsible for gathering nutrients from the ground and absorbing the water from the earth. The leaves and the steams collect sunlight for photosynthesis, water from the air and rain and carbon dioxide from animals, vehicles and factories. The stems of the Prunus serrulata are a key component of the trees reproductive system. They produce the flowers in the spring that the tree is the most famous for. These blossoms are what allows the plant the ability to be fertilized through pollination through insects like bees and beetles.

Here is a picture of me in a park in the city of Amber which is located in Bavaria Germany.
Cheery Blossom Seeds
The Prunus serrulata reproduces like most trees by producing seeds which are called gemnosperms. As I have observed the tree in my yard the seeds fall in the fall right before the leaves change color. They are blackish purple and stain everything they touch. This semester I have learned that as the tree produces seeds they are covered in a protective shell that provides food and nutrition for the seed prior to it falling on the ground. It then goes through a pollination process which makes the seed fertilized prior to it falling to the ground. After the seed is fertilized it is ready for reproduction and will fall to the ground. If the seeds take to the soil they will begin cell division and over time sprout roots, a stock and eventually branches and leaves. Once the tree has matured it will also produce seeds and the cycle will start anew.
The Prunus serrulata in the spring blooms with beautiful blossoms. This is the reason the tree has been referred to as the Cherry Blossom tree.

Germany's biome is forest. The biome forest is the home of many plant and animal species. One of the plants that live in this biome is prunus serrulata.

Cherry Blossom Tree
This is my prunus serrulata tree. It is starting to change colors because of the lack of chlorophyll in the leaves. Chlorophyll is lost due to lack of sunlight not temperature.

The Prunus Serrulata originated in Asia around the 15th Century according to the National History Museum online (2013). " It may grow about 10 feet in 10 years, but is short-lived. The average life span is 15 to 20 years." (Shaughnessy, Polomski 2006)
According to Mader, Sylvia S. (2011) "The interior of a leaf is made of mesophyll, a ground tissue composed mostly of parenchyma cells that contain chloroplasts and therefore can carry on photosynthesis which requires solar energy, water, and CO2. Eudicot mesophyll has two distinctregions: palisade mesophyll, containing tightly packed, elongated cells whose placement is antageous for absorbing sunlight, and spongy mesophyll, containing irregular cells bounded by air spaces right next to the stomata. The loose packing of the cells in the spongy mesophyll increases the amount of surface area for the absorption of CO2. But water loss from spongy mesophyll can be regulated by closure of the stomata."
The Evolution of the Prunus serrulata is complex. "Prunus serrulata is a true cherry, belonging to Prunus subgenus Cerasus within the subfamily Prunoideae in the Rosaceae." (National History Museum online 2013). According to National History Museum online (2013) It is a decorative tree from Asia and humans have done a lot to control the breading and cross breading of the tree. The tree can grow up to 20 feet tall has brown bark with paler bands of lenticels. It's leaves are 6-12 x 3-6cm, flowers appearing just before or with the leaves in clusters. The color of the buds are pink and white. The Prunus serrulata natural predator is the Japanese beetle or (Popillia japonica) according to Damien Campbell from eHow Contributor. The Prunus serrulata has not developed a natural defense against the Japanese beetle other than its natural beauty and mankind's desire to see the tree bloom. So humans take time to remove the beetles from the trees and use pesticides to kill them.
