Wet Mount of an Onion Cell Put a drop of water onto the microscope slide. It should be very thin and may curl up on itself. Place the onion sample into the drop of water on your slide. You may need to use the dissecting needle to do this. Place a coverslip onto the slide. You probably will not see the cells at this power. Switch to low power 10x. Cells walls should be visible: they will look like semi-clear grid lines. Once you think you have located a cell, switch to high power 40x and refocus. Sketch the cell at low and high power. Label the nucleus, cytoplasm, and cell wall of a single cell. Draw your cells to scale. Using the forceps, gently tear off a small piece of a leaf from Elodea. Place the Elodea leaf into the drop of water on your slide. Cells walls should be visible: they will look like dark grid lines.
Label the chloroplasts, cytoplasm, and cell wall of a single cell. The nucleus may be visible as well—it will be a large, clear figure. Questions: 1. Describe the shape and the location of chloroplasts.
Check here. Credits: 1 Prerequisite: At the very least, you need to have taken algebra and know basic trigonometry, which can be found at Khan Academy. Students use readings, videos and simulators to learn about Newtonian mechanics, fluid mechanics and thermal physics, electricity and magnetism, waves and optics, and atomic and nuclear physics. Students will complete eighteen labs using online simulators to collect their data. The course culminates with a hands-on lab created by the student and a final exam. The majority of the PDFs in this course are from that course the first unit is linked here. They originally got most of them from other places. The course I used as a guideline from GVL is free to adapt and share but cannot be used for commercial purposes. Notes: Please hold onto all of your work.

You may need to switch to another browser that supports Java. This is a tough course, but you can do it. I want you to think about how you best learn, how you best remember information.
Can you just listen to something and remember it? Do you remember it best if you write it down? Do you need to read something to get it? Use those things while you take the course. Just sit and listen. If concentrate best while doing something concrete, then take notes; write down key words. If you want something to read, take good notes to read afterwards. Choose the way that is best for the way you learn. Every day it would be great to sit down with a parent or someone else and explain about what you read. Being able to recreate the information in your own words will cement it in your mind. It also shows you really understand it. As you learn the material, stop frequently to put it into your own words. Summarize the page to yourself before you exit. This course is based on an AP physics course.

Place a large funnel into the water so that it touches the bottom of the beaker. Drop a few small potassium permanganate crystals through the straw. Remove the funnel carefully and slowly. Observe the size of the area that is coloured by the potassium permanganate at the beginning of the experiment, after 5 minutes and then after 20 minutes. Questions What do you observe happening in the beaker? What can you conclude based on your observations? Explain how using hot water would affect the results of this experiment remember that when you explain you need to give a reason for your answer.
Observing Diffusion What do you observe happening in the beaker? Answers The purple colour slowly spreads diffuses throughout the entire beaker of water, until the colour is evenly spread out. The molecules of water and potassium permanganate must be constantly moving in order for the purple colour to diffuse throughout the water and spread out evenly. The additional heat from the water gives the particles kinetic energy which enables them to move more quickly. Osmosis When the concentration of solutes in solution is low, the water concentration is high, and we say there is a high water potential.
Osmosis is the movement of water from a region of higher water potential to a region of lower water potential across a semi-permeable membrane that separates the two regions. Movement of water always occurs down a concentration gradient, i. Osmosis is a passive process and does not require any input of energy. Cell membranes allow molecules of water to pass through, but they do not allow molecules of most dissolved substances, e. As water enters the cell via osmosis, it creates a pressure known as osmotic pressure. Figure 2. Watch osmosis taking place by clicking on the following link. In biological systems, osmosis is vital to plant and animal cell survival. Hypertonic concentrated Isotonic Hypotonic dilute The medium is concentrated with a lower water potential than inside the cell, therefore the cell will lose water by osmosis. The water concentration inside and outside the cell is equal and there will be no nett water movement across the cell membrane.
Water will continue to move across the membrane, but water will enter and leave the cell at the same rate. The medium has a higher water potential more dilute than the cell and water will move into the cell via osmosis, and could eventuality cause the cell to burst. Plant cells use osmosis to absorb water from the soil and transport it to the leaves. Osmosis in the kidneys keeps the water and salt levels in the body and blood at the correct levels.
Predicting the direction of osmosis Aim To predict the direction of osmosis. To obtain this, add g of sugar to ml of water. Cut its one end to make the base flat. Make a hollow cavity in the potato almost to the bottom of the potato. Add the concentrated sugar solution into the cavity of the potato, filling it about half way. Mark the level by inserting a pin at the level of the sugar solution insert the pin at an angle into the cavity at the level Figure 2.
