A particular single-celled organism uses radiant energy to fix carbon as sugars. This organism generates ATP by breaking down sugars through a process that uses oxygen. This organism is aerobic autotroph.
Autotrophs produce their own food from the substances available in their surroundings using light through photosynthesis or chemo-synthesis.
 
        
                    
             
        
        
        
Large molecules such as hormones  materials are expelled from cells during exocytosis
<u>Explanation:</u>
The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.
 For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.
 
        
             
        
        
        
The chemical food source for the soybean plants is A (Sunlight) because once the leaves emerge, it relies on sunlight to photothynsesize to get energy.
