I plan to infiltrate the root cells. The root cells are eukaryotic, and they contain organelles, so the Nanobot Armies can invade the cells with a tough fight. I will enter the root cell through its cell wall; the rocket will penetrate the cell wall. I will neutralize the vacuole, then the nucleus, and lastly, the cell wall. Neutralizing the vacuole is important for the invasion of the root cell, because the function of the root (through the xylem) is to absorb water from the soil and give it to the stem and the leaves of the plant. The vacuole stores the water so that the water can later be fed to the stem and the leaves, and if the vacuole is destroyed, the cell cannot store any water. If the cell can’t store any water, it cannot feed any …show more content…
The xylem tissue is part of the root organ (has multiple, different xylem tissues). The single root organ is part of the root organ system (multiple root organs that perform life processes). Finally, the root organ system is part of the whole plant organism (several organ systems). Since the Nanobot Army is infiltrating most of the root cell, the root cell will be destroyed. Due to the fact that the root cells are destroyed, the xylem tissue will be destroyed since the tissues will be missing a cell. To be specific, destroying the vacuole of the root cell will destroy the xylem tissue since the xylem transports water to the plant. The vacuole would help store all the water, and if there is no vacuole, no water would be transported, and the xylem tissue would not have a job to perform. Since the xylem tissue is affected, the root organ would be affected as well. The xylem tissues are not doing their job (transporting water to the plant), so one part of the root organ would not function. Therefore, the entire root organ would not function. Since the root organ does not function, the root organ system would be destroyed as well. For example, if the heart does not function in the circulatory system, the circulatory system would be disrupted. The same thing would happen to the root organ system when the root organ does not function. Since the entire root organ is destroyed, the plant would be destroyed, as it is not receiving its needs from the root. Since the plant is destroyed, it also destroys primary consumers, since they eat plants, and the plants are dying. Because there would be less primary consumers, the amount of secondary consumers would go down (they eat primary consumers). Since the amount of secondary consumers goes down, the tertiary consumers also go down because they eat secondary consumers. Because there are less living things in the world, it would
I will get 5 test tubes and place them into the test tube rack. I will
Charles Darwin once compared the root tips of plants to “the brain of one of the lower animals” he even reported electrical signal systems in plants, much like a nervous system. More than a century after Darwin, a scientist named Mancuso discovered the center for the electrical signals, or action potentials, is located in the root tips. Even small plants had nearly 14 million root tips, all acting in a similar way to a nervous system. Humans and most animals have centralized brains, meaning it is all grouped together in one spot, forming what we envision as a brain. Plants may not have a centralized brain like humans, but that doesn’t mean they lack a brain, in fact plants have “decentralized intelligence” distributed throughout them. Since plants cannot react quickly, they have no way of defending themselves against predators, so by scattering the “brain” plants avoid dying off when damaged (Marinelli). The root tips and sensory cells allow plants to feel and react to different stimuli. It is uncertain as to whether plants feel pain, but they do respond to anesthetics and react to being damaged. For example, when a caterpillar eats a plant’s leaf, the plant begins to secrete defensive chemicals. The censor cells react to the damage being done and cause the leaf to secrete chemicals to fend off the predator, as well as repair the

Investigate the Osmosis of Potato Cells in Various Salt Solutions. Introduction I have been asked to investigate the effect of changing the concentration of a solution on the movement of water into and out of potato cells. I will be able to change the input of my experiment. The input variable is the concentration of the solution.
If a plant cell is places in a hypotonic solution the cell has a lower water concentration to that of the solution. Water will move into the cell by osmosis from a high water concentration outside the cell to a lower water concentration inside the cell through a selectively permeable membrane. The cell becomes turbid
Osmosis in Carrots Background Osmosis is the diffusion of water from a dilute solution to a more concentrated solution through a partially permeable membrane, which allows the pass of water molecules but not solute molecules. [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE]If a cell is placed in a less concentrated solution water enters because the less concentrated solution will have a high concentration of water than the inside of the cell. Once the cell takes in maximum water the cell becomes turgid. If the cell was to be placed in a high concentrated solution, water would leave the cell because the cell would contain a low concentrated solution. So in the low concentrated solution there will be a high concentration of water and in the high concentrated solution there will be a low concentration of water.
...nessing “the power of nanotechnology” to radically change the way we diagnose, treat, and prevent cancer.” The most likely method implemented will by the use of nanovectors for targeted delivery of anticancer drugs, and then heating nanoparticles that are attached to cancer cells so that the cancer cells explode. (5, 9) There are still many obstacles that must be overcome before this is a reality: from the ethical concern by some that nanobots will take control of the body to the more practical problem that this method of treatment will be very expensive and funding will be an issue. (6) But with millions of people suffering from some form of cancer, scientists are searching for cures and treatments and nanotechnology offers the greatest promise. One day, cancer may be completely curable thanks to nanotechnology which is something everyone would benefit from.
Plant defences are those mechanisms employed by plants in response to herbivory and parasitism. According to Hanley et al. (2007), “the tissues of virtually all terrestrial, freshwater, and marine plants have qualities that to some degree reduce herbivory, including low nitrogen concentration, low moisture content, toxins or digestibility-reducing compounds”. The type of chemical defence may be species specific (Scott 2008). The defences that plants possess may be in the form of chemical production or in the form of physical defences such as thorns or spikes and even through reinforced, rigid leaves. “The compounds that are produced in response to herbivory can either have a direct effect on the attacker itself (e.g. toxins or digestibility reducers), or serve as indirect defenses by attracting the natural enemies of the herbivores” (Bezemer & van Dam 2005). This essay will focus on chemical plant defences and in particular the effects of terpenes, phenolics, nitrogen-based defences as well as allelopathy in plants.

== = This experiment is based on the concept of Osmosis. Osmosis is the diffusion of water molecules from a region of high water concentration to a low water concentration through a semi permeable membrane (in this case, the cell potato cell membrane). The cell walls of the potato cells are semi permeable meaning that water molecules (which are small) can fit through but other bigger molecules such as glucose cannot pass through. The water molecules can flow both ways through the membrane, letting molecules both in and out.

Our summer trips to Colorado seemed to take forever. I was an eager four year old child who couldn't wait to get to my secret place. Every child has a special place: it might be a fort made out of sheets and couple of chairs, or maybe it's an easy chair that serves as a stage coach or a fighter plane. Maybe its a bed that becomes a ship protecting you from sharks. My special place was at my grandparents farm.
To delve into the clockwork of this technology we must start from the beginning. A plant starts its life as a single celled organism; the sperm within pollen fertilizes an egg. This egg (cell) divides to form the tissues and organs of a species. As development proceeds cells grow unique of one another and change. Different cells make up different things (ex cells in the stalk of the plant are much different than those of the piston) and these differences are attributed to the fact the different amounts of proteins in each cell.
The strong cells wall prevents bursting. The cell is turgid. If plant cells lose water the cells become limp and flaccid. Water is essential for support in plants.
