First, keeping the seeds in the same area with the same temperature and the amount of sunlight would help the odds of the fluctuation within the different concentration results. Having every bag in the same region would then factor out any skepticism that those two factors effected the overall germination. Second, if everyone has to test the various concentrations, why not test every concentration so there would be even more data tied to the germination and maybe an improvement on the experiment. A final improvement for the effect of salt concentrations on germination could be the number of trials completed. Usually in an effective experiment, many trials are done so the data can line up for any mistakes made.
MPC suppresses the production of the plant hormone gibberellic acid which is a growth stimulant that induces cell elongation. Suppression of gibberellic acid production results in decreased cell elongation and overall decrease in the vertical and horizontal elongation of stems and branches (York 1983; Kerby 1985). It should be noted that MPC inhibits cell expansion, but not cell division. MPC is not thought to be readily translocated through the plant. The overall effect of MPC on plant growth and development depends on growing conditions after it is applied.
The hormone cytokinin causes this after the exposure of light. Chloroplasts contain chlorophyll and due to this the plant turns green. 1.1 Research question For this experiment, I want to find out what will happen to cress seeds that are etiolising (growing in the dark) when they are then exposed to light. To conduct this experiment, I came up with the following research question: ‘Will exposure to light after a set period of etiolation cause a plant to de-etiolize?’ 2.
Lastly, the other fallacy derives from the water temperature. As the temperature of the water increases, carbon dioxide is produced up until its optimal temperature. In reality, when the plant attains the optimum, denaturalization of enzymes in elodea occurs so that that leads to cessation of oxygen. Similar to this situation, same result would be created when the temperature is too cold.
If the experiment was completed again, more higher concentrations could be applied to the seeds to see if the data is further supported. Either way the more trials the better and more accurate results, this applies to any experiment. Practical applications of the principles of this investigation may be using the correct concentration for a specific plant or seed. This lab shows that it is necessary to follow the directions and specifications when using the fertilizer miracle
Synthetic astaxanthin and canthaxanthin are chemically identical to the naturally occurring compounds in aquatic animals. Pigmentation strength of canthaxanthin is only half of that of astaxanthin (Hertrampf and Piedad-Pascual, 2000). Carotenoid synthesis is a highly regulated‚ integral part of chloroplast biogenesis and is intimately associated with the synthesis of other chloroplast components (i.e. lipids‚ proteins and chlorophylls). The major stimulus for carotenoid synthesis in greening leaf tissue is light (Oelmuller and Mohr‚1985)‚ however‚ some xanthophylls are also present in substantial amounts in etiolated tissues (Grumbach and Lichtenthaler‚ 1982) ‚ indicating a large portion of the pathway is operational in the absence of light (Frank et al,
A justification of why the data is being used? • The reason for why the data is being used is because we want to see how quickly duckweed can reproduce and if the habitat that it grows in has an effect on how fast or how slow it will grow as well as to see how fast it will spread due to the habitat that they are growing in. What you plan to do with the data collected?
INTRODUCTION A chimera is a single organism made up of genetically different cells. These can be male and female organs, two different blood types and many more. There are two types of chimeras :- 1. Animal chimera 2.
This supports the hypothesis that the added cytokinin induces shoot growth and the added IBA will induce root growth rather than shoot growth. The higher tolerance of monocots to auxin could be due to the structures of the inside of the monocot, meaning that the excess auxin is harder to transport around the plant, or possibly because the monocot is better able to deal with excess ethylene, the production of which is stimulated by
When punching out the leaf disks, the big veins were to be avoided, so that the leaf disks would have the same uniformity of cells. Cells that are in the veins have different purposes than the rest of the cells in the plant causing a slight difference in the anatomy. With some of the plants, it was hard to avoid the veins as they took up much of the plant. Another error to the lab is that fact that different factors affect photosynthesis. When testing the plants, it is unknown what factors are causing the plants to go through photosynthesis.
Each type of seed was designed by bioengineers, who in a way “Copy and Pasted” the desired genes and traits, which is why they cost more. For example, they can alter the DNA of a plant to increase the rate of fruit production. Another way that they increase the production is to change the DNA to allow the plants to grow close to each other, which would would produce more from the same amount of land. Ian
The Kudzu vine is an extremely belligerent and invasive plant that can grow out of control once established. Kudzu overtakes and covers all plants in its path which results in the elimination of native plant species. It can cover trees and block out the light needed for the photosynthesis process or damage the limbs of the tree with the intense weight of the vines. It also has the capability to leave land worthless for agriculture or forestry. This amazing and terrifying vine covers the South and is spreading throughout the country at an incredible rate.
