Citrus limon- Lemon




The lemon tree acquires nutrients in two ways.  The first way is through the roots in which the roots absorb nutrients and water from the soil.  Nutrients that the roots absorb include nitrogen, phosphorus, potassium, calcium, magnesium and sulfur.  These nutrients are also considered macronutrients since the plant needs large amounts of them.  The roots also provide the plant with micronutrients which include: iron, zinc, manganese, boron, copper, molybdenum, nickel, and chlorine.  The second way the lemon tree gets nutrients is through photosynthesis.  Photosynthesis occurs in the leaves of the tree and results in glucose and oxygen.  To perform phLeaf of a Lemon Treeotosynthesis the plant needs carbon dioxide which can be received from the air, water which can be absorbed by the roots, and light energy that comes from the sun.  Once these nutrients are absorbed or produced they are transported through the rest of the tree.  Water is transported via vascular tissue known as xylem and the glucose and other nutrients are transported by phloem.  If some of these nutrients are not used they are stored in the leaves of the plant for later use. 


Citrus limon is classified as a free living organism.  It is considered to be free living since it does not depend on another organism for nutrients, water or anything else to survive.  However, Citrus limon can be the host for fungi and other parasitic organisms.
