Biology Energy and Photosynthesis Quiz

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Term
Definition
Energy   the ability to do work  
🗑
Adenosine Triphosphate (ATP)   consists of adenine, a 5-carbon sugar called ribose, and three phosphate groups  
🗑
Adenosine Diphosphate (ADP)   consists of adenine, a 5-carbon sugar called ribose, and two phosphate groups  
🗑
Photosynthesis   the process that autotrophs use to convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates  
🗑
Heterotrophs   organisms that obtain food by consuming other living things  
🗑
Autotrophs   organisms that make their own food  
🗑
Visible Light Spectrum   the different wavelengths of light that we see as the colors red, orange, yellow, green, blue, indigo, and violet  
🗑
Pigments   light-absorbing molecules that plants use to gather the sun's energy  
🗑
Chlorophyll   the plants' principal pigment for gathering the sun's energy  
🗑
Chloroplasts   organelles in plant cell where photosynthesis takes place  
🗑
Thylakoids   saclike photosynthetic membranes inside chloroplasts which are interconnected are arranged in stacks known as grana  
🗑
Stroma   the fluid portion inside of chloroplast but outside of the thylakoids  
🗑
Electron carrier   a compound that can accept a pair of high-energy electrons and transfer them, along with most of their energy, to another molecule  
🗑
NADP+ (nicotinamide adanine dinucleotide phosphate)   a carrier molecule  
🗑
Chemical reaction   process in which reactants are transformed into products after passing through a high energy transition state  
🗑
Reactants   a substance that takes part in and undergoes change during a reaction  
🗑
Products   substances formed during a reaction  
🗑
Glucose   sugars generated by photosynthesis to produce complex carbohydrates such as starches, and to provide energy for the synthesis of other compounds, including proteins and lipids  
🗑
Light-dependent reactions   reactions that require the direct involvement of light and light-absorbing pigments  
🗑
Light-independent reactions   reactions do not require direct involvement of light  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
