The purpose of this experiment is to figure out why different liquids affect plants differently. To do the following experiment you need to 1. Put one plant in each pot of three pots 2. Label one pot A, one pot B & one pot C 3.
Describe all of the ways what you could prepare this plant for consumption: 3c. Image of Plant: Part Three: Other Resources Part Four: Conclusions Part Five:
Then measure the distance of each pigment starting at the bottom of the pigment origin to the bottom of the separated pigment band. In Exercise 4B: Photosynthesis/ The Light Reaction, chloroplasts are extracted from spinach leaves and incubated with DPIP in the presence of light. The spectrophotometer should be warmed up and set the wavelength to 605 nm. An incubation area should be set up, that includes a light, water flask, and test tube rack. We were provided with two beakers, one containing a solution of boiled chloroplasts and
Materials: Four plant samples Dichotomous key (a copy is found in the Module Help column at www.rechanek.com) This lab report Hypothesis: 25% Bryophyta 25% Pteridophyta 25% Gymnosperms 25% Angiosperms Procedure: Read all the instructions for this lab before you begin working! Pre-reading the procedure will give you a mental picture of what you will be doing and a better understanding of the process. Find an area of vegetation, like a backyard or a park, and select four plants of different characteristics from your chosen location. You may take pictures of your selected plants or bring samples back to your home to study. Use the dichotomous key provided to identify the phylum of your plant samples.
Based on other investigations, vitamins which are made up of organic compounds can help plants grow by providing them with essential nutrients. This time, the researchers tried to use human vitamins. So, in conducting the experiment, first, the researchers labeled the containers of each plant. They labeled the containers: A, B and C. The researchers put all three plants in an area with sufficient sunlight. For three weeks, they watered the plants once a day.
01.03 Scientific Method Scenario 2: Katherine wants to investigate if the time of day a plant is watered affects the growth of the plant. She hypothesizes that a plant watered in the morning will grow faster than a plant watered at other times of the day. Identify the specific independent and dependent variables that will be involved in an experiment to test this hypothesis. Independent variable * Time of day plant is watered Dependent variable * Growth of plant List at least five variables that should be controlled during the experiment. For each variable identified, give a specific suggestion for how it can be controlled during the experiment.
At the bottom of the petri dishes we level it with four quadrants to make sure that each of the antibiotics were placed in the right quadrant and be able to see how the bacteria acted in respect to the placement of the antibiotic. One of the quadrants was kept as the control of the experiment. There were six antibiotic but each group obtain only three of the antibiotic for each bacteria. When placing the bacteria on the petri dish we used a pipette to obtain 100uL of the bacteria onto the petri dish. With a rod (spreader) that was dip in ethanol and then place under the busen burner in order to neutralize it; we spread the bacteria on every surface area of the petri dish.
Research: Two specific topics that I would have to research on the topic are the best lighting condition for the type of plant that is being grown, and the ideal nutrients needed for the plant to grow. To find the ingredients in the soil I would have to look at the back of the bag or possibly look on the products website for details. To find the best lighting condition I would look at the packet or tag that the plants or seeds come in. This will state where I should keep the plants during the experiment. Hypotheses: I believe that changing the soil that the plant grows in to the highest nutrient rich soil will aid in the growth and survival of the vegetation –One that I will test I believe that increasing the
The reason why i think the plant growth light allowed the plant to grow much faster and fuller is because of the different types of wavelength of light generated by the light. The wavelengths that the plant growth light are different from the regular light because it produces wavelengths that the plant can use more efficiently. Plants use most of the wavelengths of light but only a certain few types of wavelengths allow the plant to operate at its full potential while doing photosynthesis. As technology improves so does the way we can grow plant more efficiently not only for home aquariums but for the masses of people around the world by growing corn and other foods faster so we can meet the demands from
(a) Peter used the equipment below to investigate growth of plants. ✓ measures the ✓ temperature of the air measures the °C ▪ measures the time ✓ for the experiment days ✓ measures the mass grams ✓ of a plant ✓ measures the length ✓ of a plant cm 4 (b) The diagrams below show four measuring containers. Which is the best container to use to measure 15 cm3 of water? Write the letter. ✓ C 1 Why did you choose this container?
