Observing the growth hormone acid on germinating seeds.
Background: Seed - the germ of a mature plant.Germination - the transition from the seed dormancy in the vegetative growth of the embryo and the formation of a seedling. Basically,germination is a process of growing the plant from the seed. Certain conditions are needed for germinations of the seeds, such as an appropriate amount of water and the right temperature. But for different types os seeds the conditions for growing chances due to their masses, relation to the sun, amount of water needed to germinate. But the growth os the seeds can be controlled and can be changed due to the fact that growth hormones could be add to speed up the process. Patter and rate of plant growth are

One of them contained a seed with a concentration of the IAA, and another Petri dish contained a seed without any hormone inside, it only included water.

Under the sun seeds didn't germinate. By providing the proper lighting conditions and giving the right temperature and moisture for the seeds, this provides a successful experiment. When they first were put just under the sun, without using an incubator, they didn't germinate at all. This could make my experiment to fail, and ir was important that they should be placed in the incubator.My preliminary experiment helped me to understand how much concentration needed to put into a cotton pad, so the seeds will germinate and it will make an experiment successful. Also it helped to determine what is better to use,soil or cotton pad. Cotton pad is making the observation more clear so i can observe each day how the root length is changing in different Petri dishes. Also preliminary experiment helped me to find out what kind of concentration should i put in each dish to see the
In the dishes, I dropped the appropriate treatment into the center, where the marks were made. Next, I closed the petri dishes, taped them up, and let them sit at room temperature for a week. Then I opened them up to take two measurements. The first measurement was the number of seeds germinated. The second measurement was to measure the seedling lengths.
The experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into
Before, I started I made a prediction for the experiment. I thought the salt on top of the seed and inside the paper towel would soak up water and dehydrate the seed and make the paper towel go dryer
After seven days, open the petri dishes and examine the seeds. Record the data in a table. Repeat procedure seven

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.
The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.
This then not only prevents the germination of the seed; however, if the plant were to initially germinate, it would be unable to grow any further, as without enough water, photosynthesis, nutrient transfer, or transpiration would be unable to occur; therefore, the plant would be unable to sustain (Growing Anything,
After finishing the entire lab experiment, I find that those were the only big problems I had. If I were to improve this experiment, though, I would find a good window ledge, buy a tape measure and have a better object to block the experimental seeds from the sun. Other than these factors, I feel this lab went very successfully and that the results were reasonably accurate.
The low-density radish-collard mix pots contained four seeds of radishes and four seeds of collards. The high-density radish-collard pots contained 32 seeds of each species. While our group replicated this 3x2 design four times to total 24 posts, we incorporated the whole class data. Therefore, there were 16 replicates for each treatment. For each pot, we filled soil up until about one inch from the top. We placed the seeds in the pot and piled on around 2 or 3 cm of soil on top. In 3 species levels, seeds were spaced as evenly as possible. In the mixed species pot, the two species were alternated so that each one had the same access to space and nutrients at the other. For each pot, we wrote down our section number, group name, and the contents of the pot. Our group worked at the first bench in the greenhouse and also contained our pots that were spread out evenly in four rows. Our pots stayed in the greenhouse for about five weeks, captured as much sunlight as they could, and got their water source from sprinklers that automatically came on twice a
This experiment began on the first day of lab by planting 12 total seeds from the F1 generation in six individual cells. Potting soil was added until each cell was a little
That volume was recorded and the peas were removed onto a paper towel. For Respirometer 2, the graduated cylinder was refilled with 25 ml of water and 25 dry peas were added. Next, enough plastic beads were added to equal the volume of germinating peas for Respirometer 1. Then, the dry seeds and the bead were removed onto a paper towel. For Respirometer 3, the graduated cylinder was filled with 25 ml of water.
The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.
This lab was a success, because it shows what happens with acid rain, and its effect on seed germination. The seeds will actually grow
Before a seed can germinate it must first shed the seed coat, a protective outer layer that protects the seed from parasites, injury, and unfavorable temperatures. Inside the seed coat is the embryo which contains the root and first leaves of the plant, called cotyledons. After the seed coat has been shed the root emerges first so that it can absorb water and nutrients. After the roots have come out of the embryo the cotyledons will follow. Some seeds need certain conditions to germinate and go
