Monitoring the Growth of barley seeds.

Introduction

Monitoring the Growth of barley seeds Introduction The reason barley is so important is because it is in our food. Farmers have the job of knowing what is in their crops and they need to know what they are putting on the crops. We are doing an investigation on the growth of the barley. We are going to monitor how much the barley grows over a period of time. We are comparing the growth of the barley seed with the nutrients it needs. Planning Factors affecting barley growth There are control variables, which can be used to change the growth of a plant. Such as the soil type, temperature, light intensity, concentrations of all the other minerals accept the one under test. They are called controlling variables because they can change the growth of the plant. When we did this experiment we needed something to hold the plant up. ...read more.

I will also be looking at the length of the roots. Another way that I could be monitoring the barley plant is to count the leaves and look at the area of the leaves. The only thing that I would change in this experiment is the nutrients. For each plant the temperature, light and humanity will stay the same. Monitoring the growth of barley I will be monitoring the growth of barley for about six weeks. I have decided six weeks so that the plants get a chance to grow properly. I will be looking at the length of the stem, the length of the roots. I will be measuring both of these with a ruler. I will also be looking at the colour of the leaves to see if they change colour over the six weeks. Safety points I had to be really careful with the solution and I made sure that I washed my hands afterwards. ...read more.

I had to be careful with the small plant they could easily break. I had to make sure that the small plant could fit in the test tube. It was also hard when I had to fill the test tube with the chemicals because I had to make sure that I filled each test tube at the same point so that it was a fair test. ...read more.

    Hemoproteins are proteins linked to a non- protein, iron-bearing component. It is the iron (heme) group attached to the protein that can undergo reversible oxidation and reduction reactions, thereby functioning as electron carriers within the mitochondria (the organelles that produce energy for the cell through cellular respiration).

    These included a grid, a scatter and a cluster. The idea of distributing the seeds in a cluster was at first not going to be used because of the fact that a cluster would result in the seeds being too close together and this could result in intraspecific competition for space, however in the end it was used.
