Preserving Cut Flowers with Different Solutions

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

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.

A black sharpie was used to label the bag “3.1” which stands for test subject three (3), part one (1). The second bag was then labeled “3.2” which stands for test subject three (3), part two (2).This was then written on the outside of the bag. One (1) tablespoon of springfield tap water was measured and poured into a small, 4 ounce, plastic, rubbermaid tub. One (1) micro essential laboratory pH strip was taken and dipped half into mixture. The pH stip was dipped into the substance for one (1) second. After the pH strip was removed it was placed against the container the pH strips came in which contains a chart. This chart matches the color of pH strips to a certain acid or base value. Once the pH was lined up the pH value was measured and recorded, the mixture was taken and poured directly onto the towel. The bag was then zipped up while applying slight pressure to the bag, without touching the seeds, to let out most excess air. Finally the bags were carried with caution to the desired location that is exposed to 11 hours of sunlight including 5 direct sunlight hours. These steps were repeated once

The materials used in this lab were distilled water, a vase with Control solution, tap water in a plastic tray. Ag+ solutions with specific concentrations such as, 0.25 (Mm), 0.50 (Mm), 1.00 (Mm), 2.00(Mm), 4.00 (Mm), and AOA solutions with specific concentrations such as, 0.2 (Mm), 0.4 (Mm), 0.6 (Mm), 0.8 (Mm), and 1.0 (Mm), eleven carnations for each group and a razor blade and an electronic balance.

In this experiment, the plants will be kept in a closed cabinet area with plant lights approximately 1’ above the tops of the cups. Keep them lit for 12 hrs each day, so equal amounts of light and equal amounts of darkness are given to the plants. Observe the moisture of the soil. Adjust the amount of solution used for watering based upon the amount of moisture of the plant’s soil. Too much or too little water can kill the plant. The last step is to observe the plants over a two week period, and check them everyday for germination. Keep track of which day each plant has sprouted above the soil and mark in a notebook in a table that day. The plants that have germinated and sprouted above the soil can be kept alive with the same solution, or with regular water, and they can be planted for the experimenter’s personal use or given

In the third week the fronds slowly started to decrease, this could have been due to other unfavourable conditions or errors in the experiment. Even though the fronds decreased in the third week in the pH 7 solution, they were still much healthier and there were much more of them than they were in any of the other solutions which is shown by the green colour of the fronds as well as the larger size of the fronds. pH 7 is the best solution out of all of them in order to sustain a healthy life in the duckweed

Some trends and patterns identified in the graphs and table is that both of the RED cellophane covered plants have the highest growth rate out of the other 4 colours.

Before the experiment took place, the Geranium leaf that was used was drawn as shown in figure 1 of the results. This diagram shows that the foil covered side (Left side), the control and the non-covered side(Right side), the variable, were both green in colour; even though, the control part of the leaf was not subjected to light and the variable part of the leaf was subjected to light..After the experiment was completed, the leaf was drawn again as shown in figure 2 of the results. This diagram shows that the control area of the leaf (non-light), turned into a murky brown colour and that the variable area of the leaf (Light), was a dark black colour. Therefore, like the chlorophyll experiment, it is assumed that the variable part of the leaf is present with starch because it turned black after iodine was applied to it, and that the control part of the leaf is not present with starch because it did not turn black after the iodine was applied to it. This proves that light is needed for starch production as the only part of the leaf that had a presence of starch was exposed to light. This could be explained by the fact that light is one of the crucial elements for a leaf to be able to photosynthesise. Once a leaf has absorbed light energy with water and carbon dioxide, it can then photosynthesise, thus creating glucose which is turned into to starch to be stored in the plant. That is why the control area

First change the color of lights, second change the level of nutrients, and third add baking soda to increase the carbon dioxide.

Purpose of Project The purpose of this project is to see if there is a difference in how plants grow based on what they are watered with. By watering five different plants with five different liquids and measuring them daily we will prove or disprove the hypothesis.

Over the 10 days of this experiment, notes were made on the observations. For the first few days, the measurements and physical appearance remained average/ almost the same. Afterwards for the following measurements and remaining days, the plants started to show discoloration and group’s number, 1, 4 and 5 showed browning in the leaves and stem. For the remaining groups everything stayed the same and the measurements increased by a fair amount each day. As the last days approached, the last two groups were showing wrinkling and shrinking in the stem and leaves. The roots had died out and the plant started to bend down and eventually was laying on the bed of cotton wool in a brown color. (Measurements shown in figure 1)

In the ecology lab for Biology Honors, the main objective was to analyze and determine the effect of acid rain on the overall health and growth of plants. After determining acid rain’s effect on plants, the objective was to learn about carbon pollution and its relation with acid rain, which would then aid in finding possible solutions to the worldwide issue of acid rain. To find out the effect of acid rain on plants, an experiment was set up using soda bottles and kidney beans. The soda bottles acted as pots for 4 beans, which were first germinated and then planted in two bottles. Two more bottles were placed underneath the pots, acting as a drainage. Over the course of about 14 days, both pots were given an equal amount of fluid in order to stimulate growth. The only difference between these two pots was that one of the plants received distilled water, while the other pot received acid rain which was created in the lab and brought to the appropriate pH level. The growth and overall health of the plants in each pot were then analyzed over the duration of the experiment. The results of this experiment came to support the group hypothesis, which stated that if a plant is regularly watered with acid rain, then its growth, development, and health will be significantly less than a plant regularly watered with distilled water.

Also that the substance with citric acid, lemon juice preserved the cucumbers the worst. These results came clear because a cucumber is made up of 95% water, so the water was able to replenish that water supply. The acetic acid, vinegar, was able to keep the cucumber somewhat preserved because acetic acids reduce softening. The lemon juice didn’t preserve at all because it’s main purpose was to kill microorganisms that cause mold, but the cucumbers weren’t left long enough to grow mold. This defeated the benefits of the lemon juice. The hypothesis, that vinegar was the best cucumber preserver was not supported. However, the knowledge of a liquid that could keep cucumbers along with their benefits was gained. If this experiment was redone, testing each cucumber for a longer period of time to see what would happen once the cucumbers begin to grow mold would be preferred. It would also help to test different liquids to see if water really is the best cucumber

The experiment can also conclude the extent that pH affects Indian Lotus growth. It may conclude that varying pH has a slight effect on Indian Lotus growth or even the ability to stop it from undergoing photosynthesis completely and kill the organism. The experiment is important in general to find how pH can affect Indian Lotus growth which can in turn affect other aspects such as the diet of locals or lead to even a decrease in Indian Lotus which is culturally significant to cultures and religions.

The leucerne plant leaves are procured from 70 days old plants and allowed to stand for two days in a humidity controlled dark growth chamber at 340C. The leaves were homogenized with 0.1M phosphate buffer (pH 7.0) containing 0.4M sucrose and 0.05M sodium ascorbate in a waring blender. Filtered homogenate was (I in Table 1) was squeezed through a gauze and centrifuged at 2000 rpm for 20 mins. The supernatant (II in Table 1) was adjusted to pH 5.0 by the addition of 1N acetic acid and allowed to stand overnight. The precipitate was removed by centrifugation and the supernatant (III in Table 1) was subjected to ammonium sulphate fractionation between 0.25 and 0.9 saturation. The ammonium sulphate precipitate was suspended in 0.0025M Mc llvain buffer (pH 5.5) containing 2.5 × 10-3 M sodium ascorbate and dialyzed against the same buffer at 40C for 20 hrs. The dialysate (IV in Table 1) was centrifuged and the supernatant was fractionated by the addition of ethanol at -50C. A fraction precipitating between 20 and 60% ethanol was collected and dialyzed in the same way.
