Plants make FOOD & ENERGY
Plants are producers |
|
|
Term
| Where do plants get energy & food? |
|
Definition
Sunlight
Use energy from sun to make ATP
Air
Use CO2 from air to make sugars |
|

| How do plants get energy & food? |
|
Definition
|
|
Term
|
Definition
Process where the sun’s energy is used to build sugars
Only plant cells carry out photosynthesis! |
|
|
Term
| Photosynthesis – the reaction |
|
Definition
carbon dioxide + water + sun energy glucose and oxygen
6CO2 + 6H2O C6H12O6 + 6O2 |
|
|
Term
| Photosynthesis – the process |
|
Definition
2 separate processes
Light reaction
Dark reaction
Occurs in the chloroplast
Allows plants to grow |
|
|
Term
|
Definition
1. Occurs in thykaloid membranes
2. Collect light energy
3. Using chlorophyll!
4. Energized electrons go through an electron transport chain to make ATP
4. Water is split to make oxygen
ATP is made |
|
|
Term
| Light Independent Reaction |
|
Definition
1. Occurs in the stroma
2. Uses ATP made in light reaction to make glucose
3. CO2 (from air) and H2O (from ground) make sugar
4. Reactions controlled by enzymes |
|
|
Term

|
Definition
Bring In
1. light
2. CO2
3. H2O
Let Out
1. O2
Move Around
1.sugars |

|
|
Term
|
Definition
1. high concentration of chloroplasts
a. collects sun’s energy
2. photosynthesis
b.makes ATP & sugars |
|
|
Term
|
Definition
1. air spaces
a. gas exchange
b. CO2 in for sugar production, remove waste O2 |

|
|
Term
|
Definition
1. carry sugars around the plant wherever they are needed
a.new leaves
b.fruit & seeds
c.roots |
|
|
Term
|
Definition
CO2 in
O2 out
H2O out
gets to leaves for photosynthesis |
