Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.
        
             
        
        
        
Given what we know, we can confirm that the three pathways of photosynthesis (C3, C4, and CAM) are all similar in that they use CO2 as the substrate in order to produce sugar, which is carbon-based.
<h3>Why are these pathways similar?</h3>
- These pathways all produce carbon-based molecules in the form of sugars or carbohydrates.
- These pathways are also similar in that they use carbon dioxide as the substrate in order to fuel these reactions and create sugar. 
- Finally, they are also similar in terms of the use of carbon and the production of carbon-based molecules in that they all use the Calvin cycle to complete this process. 
Therefore, we can confirm that each of the three pathways of photosynthesis are similar in terms of carbon and the formation of carbon-based molecules in that each of them uses the Calvin cycle in order to turn carbon dioxide into sugars.

Flattened membranous sacs; packages proteins into vesicles for secretion, modifies proteins that become part of cell membranes, and packages enzymes into lysosomes. Also called Golgi complex or Golgi body.
        
                    
             
        
        
        
I think it's hydrothermal vents? hope its right because I have short term memory loss.
