Term
|
Definition
| Use light to make their own food |
|
|
Term
|
Definition
| Still need light energy, but also rely on organics produced by other organisms |
|
|
Term
|
Definition
| Use chemicals and other organics to make their own food |
|
|
Term
|
Definition
| Rely on organics produced by other organisms for food, but also require certain organics otherwise. |
|
|
Term
|
Definition
| The small percentage of light that can be seen with the naked eye; used in photosynthesis (mainly red and blue) |
|
|
Term
|
Definition
| Organelles used in the system of photosynthesis; located in the mesophyll layer of a leaf |
|
|
Term
| Structures in a Chloroplast |
|
Definition
| Outer/Inner Membranes; Stroma; Thylakoids/ Thylakoid Lumen; Grana |
|
|
Term
|
Definition
| Main pigment in photosynthesis; absorbs red and blue regions of visible lights; green light is reflected |
|
|
Term
|
Definition
| Made of smaller rings composed of carbon and nitrogen atoms; absorbs light energy |
|
|
Term
|
Definition
| Makes the molecule extremely non-polar |
|
|
Term

| Equation of Photosynthesis |
|
Definition
6CO2+12H2O------------------>C6H12O6+6O2+6H2O
(Light Reactions) |
|
|
Term
|
Definition
| H2O is oxidized; CO2 is reduced |
|
|
Term
|
Definition
| First half of photosynthesis; contains photosystems I and II |
|
|
Term
|
Definition
| Second Half of Photosynthesis |
|
|
Term
|
Definition
| First step of the light reactions |
|
|
Term
|
Definition
| Second part of light reactions; produce NADPH |
|
|
Term
|
Definition
| Direction of electron movement, the actual movement: the path by which electrons move through photosystems II and I |
|
|
Term
|
Definition
| Diffusion of ions across a selectively permeable membrane, relates to the generation of ATP by moving H+ across he membrane |
|
|
Term
|
Definition
| only uses photosystem I and produces ATP, but not NADPH |
|
|
Term
| Carbon fixation reductions |
|
Definition
| builds up from smaller molecules by using ATP and the reducing power of electrons carried by NADPH |
|
|
Term
|
Definition
| Practically pointless reaction where O2 is consumed and organic fuel, CO2 is used, but no ATP or sugar is produced |
|
|
Term
|
Definition
| Plants that minimize the cost of photorespiration by incorporating CO2 into four-carbon compounds in mesophyll cells |
|
|
Term
|
Definition
| plants that open their stomata at night |
