"Home Is Where The Heart Is"

 

 

P. sativum plants live in the temperate regions. They grow and produce best in regions were the summer's temperatures are not too hot; they prefer temperatures of 55-64^oF. Developing best in the spring, cool summers, or the beginning of fall, peas grow best in sandy-loam soils. Sandy-loam soil is a combination of sandy soil(consists of large particles which allows water to move through) and loam soil(absorbs moisture well). Although the sandy-loam soil is preferred, garden peas can grow is many other types of soil. The soil is best when it is well-drained and contains lime and other necessary organic matter.

They are native to the eastern Mediterranean areas. Growing from the regions of Turkey east to Syria, Iraq, and Iran where they initially grew in rocky areas. Nowadays, the pea has been cultivated and is typically grown in gardens for commercial sale or personal use.

 

Below is a map showing the Middle Eastern countries, which are the sites in which the first plants and crops of Pisum sativum are believed to be cultivated. Although these plants initially grew in rocky soil, when they moved to other soil types specific adaptations allow these plants to grow.

Nutrition  

Dinner time... come and get it!!

 

Being consumed as a delicious snack is how we can gain nutrition from these little pods. The plant however requires photosynthesis to convert the water and carbon dioxide into sugars and oxygen, with the help of sunlight. The equation for photosynthesis is as follows:

 

                                 sunlight

6H₂O + 6CO₂ --> C₆H₁₂O₆ + 6O₂

 

The wall of the pods of Pisum sativum contains two separate layers that are involved in photosynthesis. The outer most layer is used to collect the CO₂ from the atmosphere and the inner most layer is used to collect any CO₂ given off from the developing seeds inside the pod. Once the sugars are formed they will need to be transported throughout the plant. Plants use a vascular system comprised of phloem and xylem. The phloem is used to transport the necessary sugars and nutrients created and obtained. The xylem is a system used to transport the needed water to the cells. Plant cells can contain a vacuole, which is used to hold and store water. The sugars that are made within the cell are stored as starch.

 

These plants also require the conversion of nitrogen in order to survive. Pisum sativum has developed a relationship with different bacteria and fungus to get the needed nitrogen. Without these organisms, Pisum sativum would not be able to survive as well. This plant has developed a dependency on the bacteria/fungus to aid in the uptake and fixing of not only nitrogen but other nutrients as well. To see more adaptations Check This Out!
