I believe that on the Naive B-cell the antibodies exist as transmembrane proteins. A naive b-cell is a type of b-cell that has not been exposed to an antigen. When exposed it becomes either a memory B cell or a plasma cell that secrete antibodies specific to the antigen that was originally bound.
Mitochondria - The mitochondria is referred to as the power house of the cell. Its main function if to produceenergy for cell by the process of cellular respiration. The energyproduced is ATP. Endoplasmic Reticulum - It is a network for transportation of certain substances in and out of the nucleus.
They convert a lot of their waste into useful substances through photosynthesis. Gaseous wastes are excreted during respiration through the plant's stomata and root cell walls. At night, when photosynthesis cannot occur, excess water is released through the tips of the leaves.
Other waste products are released as leaves and flowers fall off of a plant. In addition to oxygen, water and carbon dioxide, other plant waste products include resins, saps, latex and tannins. Some of these products are released into the soil surrounding the plant.
