Stamen | Male reproductive part of the flower, several of them are found surrounding the pistil and make the pollen, or sperm of the plant |
Cellular respiration | The process where the mitochondria of a cell breaks down glucose with oxygen to make carbon dioxide, water, and energy in the form of ATP; done in both plant & animal cells |
Pollination | The process where the pollen from the stamen lands on the pistil of the flower |
Fertilization | Process where the sperm combines with the egg cell to make a fertilized egg cell, or zygote |
Stimulus | Anything that causes a reaction or change in an organism; ex: gravity, light, water, a chemical, food, sound |
Transpiration | The loss of water through the leaf of a plant |
Tropism | A plants growth in response to a stimulus; ex: stems & leaves grows towards the light, roots grow down to where gravity is pulling on them |
Dormant | The process when plants shut down their growth due to less sunlight or water and lose their leaves until the amount of sunlight or water increases; similar to hibernation in animals |
Phototropism | The process where the stem and leaves grow towards the light source to get more light for photosynthesis |
Consumer | Organisms that cannot make their own food and must eat or absorb the nutrients to get energy; also known as a heterotroph |
