Terms | Definitions |
|---|---|
 Epidermis | outer cell layer of a leaf |
| Cuticle | waxy layer on top and sometimes on bottom, protects the leaf and conserves water |
| Palisade layer | most photosynthesis, right below upper epidermis |
| Spongy layer | some photosynthesis but mostly gas exchange, right below palisade layer |
| Stomates | holes on the bottom of the leave for gas exchange and water loss |
| Guard Cells | regulate opening and closing of stomates |
| Chloroplast | double membraned organelle where photosynthesis occurs |
| Stroma | fluid inside chloroplast |
| Thylakoids | where photosynthesis occurs, in stacks called grana, filled with chlorophyll |
| Photosynthesis equation | 6CO2 + 6 H2O + light = C6H12O6 + 6O2 |
| Light dependent reactions | convert solar energy into NADPH and ATP, oxygen is released as waste |
| Light independent reactions | Powered by NADPH and ATP from light dependent reactions, makes 2 G3Ps out of ribulose bisphosphate |
| Xylem | transports water and minerals from soil, made up of tracheids and vessel elements |
| Phloem | transports food from photosynthesis, made up of sieve cells (which carry the food), and companion cells (which help the sieve cells) |
| Stamen | male part of the plant, makes pollen (anther) |
| Pistil | female part of the plant, contains stigma, style, ovule, and ovary |
| Ovule | becomes seed |
| Ovary | becomes fruit |
