Ivy Plants.

Introduction

Ivy Plants. Prediction: I predict that the ivy plant that grows on the south side of the wall will be smaller than the north facing ivy. This is because they have less limiting factors affecting them such as availability of light. The south side ivy have no problem with availability of light as the earth is tilted on its axis facing the sun, so this side has more sunlight. The purpose of the leaves to be able to photosynthesise, so I think that the north leaves will be bigger in size as they need a larger surface area in order to photosynthesise at the same rate as the smaller south ivy. Conclusion: For the ivy growing on the north side of the wall the results are generally very varied. The graphs show skewed results, as there is an uneven distribution of growth by the plant, and there is no pattern between the data collected. Between 50-80mm on the north petiole length there are more results, with the highest amount being 6 petioles at 75-80mm in length. The north leaf length has the most in the group 30-35mm with 11 petioles in this category. ...read more.

Middle

You will find the plants in hot climates have to adapt by having a thicker layer of wax. This can affect the ivy leave because there will be more water vapour on the south side as temperature is higher, so the air is more saturated causing less transpiration to occur. The north leaves have a large surface area that can aid transpiration but they have long petioles that restrict surface area to make transpiration more difficult, this is an example of a plant adapting to its environment. So the north ivy leaves are more varied than the south as shown by the results, proving my prediction correct. The results confirm that my prediction is correct. This is due to the earth's tilt on its axis causing the availability of sunlight to be more limited on the north side. This caused the north ivy to grow larger leaves and petioles to deal with the situation, as they would need a bigger surface area to trap the sunlight for the photosynthesis process and longer petioles to reach the sunlight on the south side of the wall. ...read more.

Conclusion

I would then use universal indicator and see what colour the soil changes. I would compare the colours against a pH chart. If they were different then this result would support the conclusion as this could affect the process of photosynthesis. The colour of the leaves can be recorded against for example a colour chart also the total height can be measured, this can also show the amount of chlorophyll in the plant, which is also needed in photosynthesis. This too can support the conclusion, as I know from my results that the north ivy leaves were bigger in size thus having a larger surface area. The larger surface area could mean that there is more chlorophyll present or the same amount present as the smaller south ivy leaf, if that is the case than genetic variation has occurred and the plant has had to adapt to its surroundings. The total height of the north and south ivy plants can be subtracted to note the difference. Also the location where the plant is growing for example under a tree at the top or bottom of a hill. All these factors can help further the investigation to determine why the dimensions of the north and south ivy plants differ. By Amareen Bhambra.11B. ...read more.

  1. An Investigation into Water Loss from Plants.

    According to the prediction no water should be lost through the top surface of the leaf but the experiment shows a 2.376% mass loss through this surface, whilst the microscope findings showed that there were no stomata on the top surface therefore the loss should have been prevented by the waxy cuticle.

    I believe that I made a fairly accurate prediction for this experiment. I predicted that the 3 variables would be proportional, and I was correct, in fact, they have turned out to be directly proportional which is a benefit. Also, I have learned that the number of leaves (more to

  2. The investigation is aiming to look at transpiration.

    {3} LIGHT: light affects the rate of transpiration because it has an effect on the opening and closing of the stomata. As stomata open in the morning, the rate of transpiration increases, decreasing at a duck when stomata are closed.

    They reflect green light, which is the reason why the leaves appear green. The more light availability there is the more likely light energy is to get absorbed at the correct wavelength. Different pigments absorb different wavelengths of light. The Light-Dependent Stage This stage has two main functions.

  2. Water and Mineral Nutrition in Plants

    Water and dissolved minerals move into root in the root hair region by diffusion and active transport From the root hairs, nutrients move through the Cortex, mostly between cells, called the apoplast pathway, and into the stele via the endodermis.
