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.

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. How temperature affects the rate of photosynthesis.

    or it was not a healthy plant. This reduced the reliability and the accuracy of the experiment considerably. * Collection of oxygen: The end of the potometer was attached to end of the stem of the elodea. As we know most of the oxygen is released from the stomata pores in the lower epidermis of the leaves.

  2. Factors affecting the rate of transpiration

    From this it is possible to calculate the gradient of the line. The gradient of this line is 0.324. By increasing the wind speed to stage 1 (lowest wind speed) the water uptake by the plant increases and this line again is linear and also has a gradient.

    * Using the metal spatula spread an even layer of Vaseline across both the top and bottom surface of all leaves on the remaining 5 shoots and place in test tubes and put them in a test tube rack and label it 4.

  2. The investigation is aiming to look at transpiration.

    The amount of transpiration through these is relatively insignificant; this is known as lenticular transpiration. EXTERNAL FACTORS AFFECTING THE RATE OF TRANSPIRATION This includes all aspects of the environment, which alter the diffusion gradient between the transpiring surfaces and the atmosphere.

    Light energy is trapped in the chloroplast lamellae by photosynthetic pigments which are either chlorophylls e.g. chlorophyll a and b or caratenoids (e.g. carotene and xanthophylls). The chlorophyll a pigment absorbs light energy in the red and blue wavelengths of light in the spectrum.

  2. Water and Mineral Nutrition in Plants

    Needed gases are obtained by diffusion from the atmosphere, and will be discussed a bit more later. Water and most minerals must be absorbed as water-soluble ions from soil(never dirt) via the roots. Soil serves as the: * Reservoir for many mineral ions * Storage for some mineral ions The
