1. chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section 
2. light (either natural sunlight or artificial light, like from a light bulb)
3. carbon dioxide (CO2)(a gas found in the air; one of the gases people and animals breathe out when they exhale)
4. water (which the plant collects through its roots)
5. nutrients and minerals (which the plant collects from the soil through its roots)
Did researching for you so I hope this helped? :)
        
                    
             
        
        
        
 it is true do y'all learn this I health or what?
        
                    
             
        
        
        
It's not a hypothesis because it's asking a question for example a hypothesis is a statement supported by evidence so for example "my hypothesis would be the temperature does affect the cohesion of water to penny because of this and that"
hope this helps
