Osmosis Lab Report

Introduction
There are about a million different kinds of seeds in our world with all of the different types of plants that we have. One type of seed that takes between three to five days to germinate is a daikon radish. The radish (Raphanus sativus ) originated from China. It was commonly seen and eaten by the people of Egypt long before the Egyptians started to construct their very own pyramids. Later on, radishes became a common vegetable to eat in Greece, and since the radish meant so much worth for the Greeks, they even sculpted this kind of food out of pure gold. There was a German botanist who stated that he had observed some radishes weighing in at about 100 pounds in 1544. Even English colonists were among the many people to plant
Germination is the development that a seed undergoes in which it is trying to grow back into a plant, and this process is completed in just a few amount of steps. The first step of germination is the uptake of water by the seed. This is the part where osmosis takes place. Osmosis is the diffusion of water across a selectively permeable membrane in which the water moves from a high concentration to an area where there are water molecules with a low concentration. Osmosis is similar to diffusion in the way mentioned earlier with the molecules moving from high to low concentration. Another similarity that osmosis shares with diffusion is that both processes work as passive transports. This means that they do not need any kind of energy in order to transfer the molecules from one concentration to the other. Once the seed absorbs water, the seed coat or shell begins to crack open and this results because the cell, which in this case is the seed, has been placed in a hypotonic solution. This causes the seed coat to expand/swell as equilibrium is reached with the solution. The next step of germination is for the seed to take in as much oxygen as
Salt is a substance that prevents from osmosis taking place which leads to the seed not receiving any water uptake so it is not able to grow at all since there is no energy provided for its growth. Is a seed able to become tolerant of salt? Quinoa is known to have salt tolerance, but it is still shown in this experiment that the quinoa surrounded by distilled water still had much more growth than the quinoa placed with a high concentration of salt. The results were clear that in the distilled water, the germination of the seeds was one-hundred percent. It was evident that the NaCl brought down the numbers of the total amount of germinated seeds (Panuccio, et. al,
