CO2 = Carbon + two Oxygen
Glucose= C6H12O6 = six Carbon + twelve Hydrogen + six Oxygen
so the answer is Carbon and Oxygen. 
        
                    
             
        
        
        
<span>AUTOTROPH 1.	an organism that can make its own food	
Plants like algae are autotrophs. They produce their own food with the use of light, carbon dioxide, water, and other chemicals that are vital in their food producing activity. Aside from plants, there are autotroph organisms. An example of this is phytoplanktons. 
CALVIN CYCLE 2.	the dark reaction process of photosynthesis that uses carbon dioxide for the synthesis of carbohydrates	
The Calvin Cycle has three phases. These are 1) carbon fixation, 2) reduction reactions, and 3) RuBP regeneration. 
This cycle occurs in the stroma of the chloroplast and it converts carbon dioxide and other chemical compounds into glucose.
CAROTENOID PIGMENT 3.	a pigment ranging in color from yellow to red; helpful in capturing the Sun's light energy for use in photosynthesis	
Carotenoid is a plant pigment. It produces yellow, orange, and red colors of many fruits and vegetables. Carotenoid pigment is identified as a class of phytonutrients that benefits human health. People who consumes carotenoid rich fruits and vegetables enjoys the antioxidant property of the food as well as the Vitamin A that some carotenoid convert into. 
CHLOROPHYLL 4.	a green pigment in plants that serves to trap the Sun's energy for photosynthesis	
Chlorophyll is the combination of two Greek words "chloros" and "phyllon" which means green and leaf respectively. This pigment also contributes to human wellness as consumption of plants rich in chlorophyll are proven to be very healthy. These health benefits are 1) helps fight cancer, 2) improves liver detoxification, 3) speeds up the healing of wounds, 4) improves digestion and helps control weight, and 5) protects skin from skin virus like cold sores.
CHLOROPLAST 5.	the tiny body that contains chlorophyll; part of the cell in which photosynthesis takes place	
Chloroplast is a type of plastid that can be distinguished from other plastids due to its green color. Chloroplast is the only plastid that contains chlorophylls a and b, thus its green color. 
PHOTOSYNTHESIS 6.	a process that involves the use of carbon dioxide and water in the production of glucose and oxygen using the Sun's energy	
RADIATION 7.	transfer of heat or energy through rays of various wavelengths
</span><span>Radiation is defined as energy travelling through space. Sunshine or sunlight is an example of radiation. Its ultra violet rays radiates heat on the earths' surface which in turn helps our autotrophs undergo photosynthesis.

Answer - Many Types Such as 
Golgi Body
Mitochondria
Nucleus
Chloroplast 
Endoplasmic Reticulum 
Reasoning - These are specialize Organelle which function in each part of doing their duty require the layers to keep it separate in maintaining certain materials they receive within the cell.
