Photosynthesis |
Process in which plants convert radiant energy into chemical energy through a chemical reaction converting carbon dioxide and water into oxygen and glucose |
|
Cellular Respiration |
Process in which living things convert glucose into energy (glucose + oxygen -> carbon dioxide, water, energy) |
|
Transpiration |
Evaporation of water through stomata in a plant's leaves |
|
Xylem |
Plant tissue of nonliving cells forming tubes that transport water from the roots to stems and leaves of plants. |
|
Phloem |
Two way passage in plants that transports glucose |
|
Phototropism |
A plant's growth response to light Positive = towards light Negative = away from light |
|
Geotropism |
A plant's growth response to gravityPositive = down/with gravityNegative = up/against gravity |
|
Tropism |
Growth response of a plant to external stimuli in the environment |
|
Stomata |
Openings in a leaf where water exits during transpiration |
|
Adhesion |
Water molecules sticking to other surfaces (ex: straw, paper towel, xylem tubes) |
|
Cohesion |
Ability of water molecules to stick to other water molecules |
|
Glucose |
A sugar produced during photosynthesis. Source of food for plants and other organisms. C6H12O6 |
|
Capillary action |
Movement of water through a tube |
|
Chlorophyll |
Green pigment in plants that absorbs radiant energy from the sun. Gives plants their green color |
|
chloroplast
|
a structure inside plant cells that contains chlorphyll |
|
starch
|
stored in leaves, roots and fruits |
|
turgor pressure
|
the rigidity of plant cells filled with afluid called cytoplasm. If there is notenough water filling the cells, the tissues wilt (low t.p.) Whenwater is available, the turgor pressure increases, opening the guard cells andtranspiration continues |
