| what is photosynthesis? | the transfer of energy in light and store it within organic compounds |
| what is a chloroplast? | organelles found in the cell of plants and algae, absorption of energy during photosynthesis |
| what are the characteristics of chloroplast? | 1.) surrounded by a pair of membranes
2.) inside the inner membrane is another system of membranes called thylakoids |
| what are grana? | connected and layered thylakoids to form stacks of grana |
| what is a visible spectrum? | the array of colours, ranging from red to one end to violet is called the visible spectrum |
| where are chlorophylls located? | in the membrane of the thylakoids |
| what is the difference between chlorophyll A and B? | chlorophyll A absorbs less blue light but more red light than chlorophyll B absorbs |
| what are carotenoids? | accessory pigments found in the thylakoid membrane, including the yellow, orange and brown |
| what does calvin cycle produce? | organic compounds, using the energy stored in ATP and NADPH during light reactions |
| what happens in calvin cycle? | in the calvin cycle, carbon atoms form CO2 in the atmosphere are bonded, or fixed into organic compounds. (carbon fixation) |
| where does the calvin cycle happen? | within the stroma of the chloroplast |
| what factors affect photosynthesis? | light intensity, CO2 levels and temperatures |
