Terms | Definitions |
|---|---|
 Sunlight | Plants need to photosynthesize; leaves shaped to maximize sunlight intake |
| Gas Exchange | Plants require oxygen, CO2 for cellular respiration, photosynthesis; must also expel excess oxygen |
| Water and Minerals | Plants may lose water through transpiration, is consumed in photosytnehsis; thus, land plants evolved structures to limit water loss and speed water uptake; absorb minerals with water |
| Minerals | Nutrients in soil needed for plant growth |
| Land Plant Ancestor | Similar to green algae; mostly unicellular |
| Why Are Green Algae Plants? | Cell wall and photosynthetic pigments similar to plants; genomes show them to be closely related |
| How did water lack shape terrestrial plant evolution? | Plants were pressured to become more resistant to drying rays of sun, more capable of conserving water, and more capable of reproducing without water |
