Raadish Seeds

My prediction is that as the concentration increases, the potato cell will lose more weight. This is because of the osmosis of water particles from the potato cell cytoplasm to the solution, resulting in a loss of weight. As the concentration decreases, the potato will lose less weight until a certain point where the osmosis of particles in and out of the potato cells will be equal. I also predict that as the salt

In site D the data throughout the 5 days all 5 seeds stayed at 0 cm. The data suggest that site D had salt in the water, causing radish crops to fail. This data is also the experimental group and is important to the experiment because the data shows us the salt storage facility is the reason why the plants are not growing. This data can be compared to A to get more

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

In class, we did the carrot lab to demonstrate the movement of water going into and out of cells. Before we did this experiment, we made hypotheses. I hypothesized that the carrot soaked in fresh water would lose mass and shrink because just like your finger-tips after a bath, they become shriveled. I also thought the carrot soaked in salt water would gain mass because I thought the salt water would move into the carrot, creating the mass to be greater. After all, my hypotheses were wrong. After soaking the carrot in fresh water and salt water for 24 hours, we found that the mass of the carrot soaked in fresh water increased by 6.3% and the mass of the carrot soaked in salt water decreased by 0.5%. This is because of osmosis. Osmosis is when

If I have 5ml of lemonade and 5ml of milk of magnesia and dilute each liquid with 5ml of tap water and apply each solution twice to ten radish seeds, I believe the seeds will grow at a slower rate than radish seeds with 10ml of tap water.

Therefore, I was correct in my hypothesis that dark will have an effect on the germination of radish seeds. Also, I was very close in predicting that the seeds grown in the light will germinate twice as much as the seeds grown in the dark; the control seeds grew a little less than double the size of the experimental seeds. Ultimately, my experiment proved that light is a very important factor in the growth of any plant. However, I’ve learned that seeds grown in the dark will germinate, though slowly, as

If saltwater is applied to a plant, the plant would shrivel up and die. This is a result of the water moving out of the cells in order to try to balance the concentration of solute compared to inside the cell. The water movement out of the cell would cause the cell to shrink and the lack of water would eventually cause the plant to die.

51) A botanist wanted to see if a new strain of corn could germinate in soil that was too salty for regular corn. She conducted a study on the germination success of seeds from the new strain that were exposed to various levels of salty soil, from zero to normal (100mg/L) to high (200 mg/L) to very high (400 mg/L) to normally lethal (800 mg/L)

Paulina Jasmin Torrez The Potato Tonicity Lab Anatomy and Physiology Lab February 6, 2016 Most experiments dealing with the reaction of a human or a plant towards a hypotonic, hypertonic, and isotonic solution are to study the process of osmosis in each dependent. Before I begin, I will touch on some common background information, (definitions and differences), you need to know before you begin. The main definitions are the 3 solutions (hypotonic, hypertonic, and isotonic), diffusion, and osmosis. A hypotonic solution is when the solution surrounding the dependent has lower concentration of salt than the inside.

The Effect of a Solute in Osmosis through a Solanum Tuberosum Introduction: In this experiment, I will be studying if the type of a solute in water affects the rate of osmosis through the insides of a potato. I will be using three water solutions, one with salt and one with sugar, and plain water as a control group. Two of the solutions will have 250 milliliters of water with molarities of one for the two salt and sugar solutions. There will be two other solutions that will have 250 milliliters of water and have molarities of two for both salt and sugar solutions, so overall, there will be five solutions.

For this experiment, my group had several leaves of spinach and hole punched 40 disks out of the spinach leaf. In order to avoid any bias results, we made sure to avoid hole punching any veins in the spinach. After that we filled 4 cups each with 100 milliliters of carbon water. Each cup would have a different amount of salinity, the first cup would be the control group which would have no salt in it. The second cup would have ¼ of a teaspoon of salt in it, the third cup would have ½ of a teaspoon of salt in it, and the fourth cup would have ¾ of a teaspoon of salt in it.

Our hypothesis for this experiment was correct, the cytoplasm of the cell did shrink up because of osmosis. When we observed the onion without salt solution, the cells seemed to be full of cytoplasm and well nourished. Then, after we had filled the pipette with salt solution and added several drops to the curved section of red onion, we observed the onion with a microscope and we saw a noticeable change in the cells. The cells in the onion seemed to look shriveled up. The cytoplasm that had once filled up the cell, was almost gone with only a little amount of it remaining in the

The purpose of this lab is to test the effect of osmosis on cucumber slices. If a cucumber slice is placed in a hypertonic solution, then the mass of the cucumber slice will decrease. Whereas, if

Purpose: To see the effect of an acid introduced during seed germination, on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better, and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.

SFSE-G was prepared and characterized from the hydroalcoholic extract of fenugreek seeds as previously reported [15]. Two peaks namely peak A (trigoneoside Ib) (76%), and peak B (vicenin-1) (15%) were observed in HPLC at RT = 2.2 min and 3.2 min respectively. The corresponding compounds were isolated and characterized using TLC, 1HNMR, and 13CNMR analysis.
