Question
Answer
Autotroph   An organism that produces its own nutrients from inorganic substances.  
🗑
Carotenoid   Class of pigments present in thylakoid membrane of plants that aid in photosynthesis  
🗑
Chlorophyll   A green photosynthetic pigment present in plants  
🗑
Granum   A stack of thylakoids in a chloroplast  
🗑
Photosystem   A cluster of chlorophyll and other pigments molecules in the thylakoid membrane of chloroplast that harvest light energy for the light reactions of photosynthesis  
🗑
Stroma   Te jelly-like solution surrounding the thylakoids in a chloroplast  
🗑
Light Reactions   The initial reactions in photosynthesis which are triggered by the absorption of light by photosystem 1 and 2  
🗑
Chemiosmosis   A process in which the movement of protons down their concentration gradient is coupled to to synthesis of ATP  
🗑
Electron Transport Chain   A series of molecules found in the inner membrane of the chloroplast through which electrons pass causing the build up of protons on one side of the membrane  
🗑
Pigment   A substance that gives another substance or a mixture its color  
🗑
Chloroplast   Plant cell organelle where the process of photosynthesis takes place  
🗑
Thylakoid   A membrane system found within chloroplast that contains the components for photosynthesis  
🗑
Calvin Cycle   A biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP  
🗑
Stomata   One way openings in a leaf or stem of a plant that enable gas exchange to occur  
🗑
C4 Pathway   A carbon-fixing process in which carbon dioxide is bound to a compound to form a four-carbon intermediate  
🗑
Carbon fixation   The synthesis of organic compounds from carbon dioxide, such as in potosyntesis  
🗑
CAM pathway   A water-conserving, carbon-fixing process in which the plant takes in carbon at night and fix it into various organic compounds and releases it during the day  
🗑
Heterotroph   An organism that obtains organic food molecules by eating other organisms or their byproducts  
🗑
Primary electron acceptor   A acceptor of electrons lost from chlorophyll a within the thylakoid membrane of chlorplasts  
🗑


   

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.
