- What changes do you notice in your plants this week? Describe the overall appearance of your plant. A: The plant is doing well. It's grown quite a bit and it's now green and leafy, but not as big as the other plants.
- How do your plants participate in the movement of water in the biosphere? How do your plants' roles in the water cycle relate to the changes you observed in your plants this week? A: Plants take in the water and have it go into the soil, allowing them to grow. The only reason why our plant has grown is because of the fact that they have been partaking in water from it's roots.
- How do your plants participate in the movement of carbon in the biosphere? How do your plants' roles in the carbon cycle relate to the changes you observed in your plants this week?A: Plants intake the carbon in the air along with sunlight to allow photosynthesis. The fact that the plant is healthy shows that it is taking in carbon properly.
- How do your plants participate in the movement of nitrogen in the biosphere? How do your plants' roles in the nitrogen cycle relate to the changes you observed in your plants this week? A: Plants take in nitrogen after rain, or just from water and use it to fortify itself and strive. While it hasn't rained yet, the plants still take in the water that we give it, allowing it to grow and not wither.
Fertilization occurs in flowering plants through the process of fertilization. The center of the flower has long thin filaments with anthers at the top. This is called the stamen. Four pollen sacks are located in the plants anthers which contain MMCs, Micro Mother Cells. Each of the pollen sacks produces eight pollen grains, the sperm cells from the MMC. Once the pollen grains inside each of the sacks are ready the anthers will burst open vomiting the sticky pollen onto the flowers stamen in a process called dehiscence. The flowers bright colorful pedals lure insects inside to drink its nectar, located at the flowers base. Once the insects climb into the flower the sticky pollen from the anthers gets stuck on its feet, legs, or body. In the process of cross pollination the insect that collects this sticky pollen will transfer it to another flower pollinating it in the process. In the process of self pollination the pollen will be moved from the stamen to the pistol/carpal of the flowe...
