Okra is an "Old World" vegetable. The exact place of origin is still matter of debate. Over the centuries, many cultures have embraced okra and used it to create traditional dishes. Mediterranean and African recipes combined with tomatoes a new world fruit were created after the Columbian Exchange.
Osmosis through the Cell Membrane of an Egg Introduction: Transport can be either passive or active. Passive transport is the movement of substances across the membrane without any input of energy by the cell. Active transport is the movement of materials where a cell is required to expend energy.
In the case of this lab the discussion will be centered on passive transport. The simplest type of passive transport is diffusion. Diffusion is the movement of molecules from an area of higher to an area of lower concentration without any energy input. Diffusion is driven by the kinetic energy found in the molecules.
Diffusion will eventually cause the concentration of molecules to be the same throughout the space the molecules occupy, causing a state of equilibrium to exist. Another type of passive transport is that of osmosis. Osmosis is the movement of water across a semi-permeable membrane.
The process by which osmosis occurs is when water molecules diffuse across a cell membrane from an area of higher concentration to an area of lower concentration. The direction of osmosis depends on the relative concentration of the solutes on the two sides.
In osmosis, water can travel in three different ways. If the molecules outside the cell are lower than the concentration in the cytosol, the solution is said to be hypotonic to the cytosol, in this process, water diffuses into the cell until equilibrium is established.
If the molecules outside the cell are higher than the concentration in the cytosol, the solution is said to be hypertonic to the cytosol, in this process, water diffuses out of the cell until equilibrium exists. If the molecules outside and inside the cell are equal, the solution is said to be isotonic to the cytosol, in this process, water diffuses into and out of the cell at equal rates, causing no net movement of water.
In osmosis the cell is selectively permeable, meaning that it only allows certain substances to be transferred into and out of the cell. In osmosis, the proteins only on the surface are called peripheral proteins, which form carbohydrate chains whose purpose is used like antennae for communication.
Embedded in the peripheral proteins are integral proteins that can either be solid or have a pore called channel proteins. Channel proteins allow glucose, or food that all living things need to live, pass through. In the syrup solution, there will be a net movement of molecules out of the egg, and in the water solution, the molecules will diffuse in and out of the cell at equal rates.
The materials used in this lab were 2 fresh eggs in the shell, an overhead marker, ml of water, graduated cylinder, 1 large beaker, 2 medium beakers, 1 small beaker, white vinegar, Karo syrup, distilled water, pencil, paper, lab apron, lab goggles, saran wrap, masking tape, plastic tray, tongs, electronic balance, osmosis lab sheet, and computer.
On day 1, measure the masses of both the eggs with the shell. Label 1 beaker vinegar, and then use the graduated cylinder to measure mL of vinegar to put in the labeled beaker.
Place both eggs in the solution place a small beaker on top of the eggs, if necessary then cover. Let the eggs stand for 24 hours or more to remove the shell. On day 2, record the observations of what happened to the eggs in the vinegar solution.
Carefully, remove the eggs from the vinegar, gently rinsing the eggs off in water.
Clean the beakers used for the vinegar solution preparing them for the syrup solution, and then label the 2 medium beakers syrup. Before the eggs are placed in the syrup solution record the mass of both eggs then put it on the datasheet.
To use the properties of both diffusion and osmosis to see the affects of either maple syrup or water on a shell-less raw egg over a three day period. Also, applying properties hypotonic, hypertonic, and . (Click here for bottom) M m M. Latin, Marcus.A praenomen, typically abbreviated when writing the full tria nomina.. M'.

There’s been a surge of interest in bone broths recently as the benefits of collagen (the main ingredient of these broths) gets the thumbs up for a variety of dietary (ketogenic/paleo/Banting) and wellness reasons: as the foundation for strong connective tissue, sturdy bones and beautiful skin, as well as rapid wound healing and the easing of joint pain.
After that has been done, place the eggs in the beaker, pouring enough syrup to cover the eggs, cover them loosely and let them stand for 24 hours. On day 3, record the observations of the egg from the syrup solution.
Carefully, remove the eggs from the beakers, gently rinsing the syrup off of the eggs. Pour the remaining syrup in the container provided by the teacher. Clean the two beakers used in the syrup solution, preparing them for the water solution.
Before the eggs are placed in the water solution record the mass of both eggs then put it on the datasheet. After that has been done, using a graduated cylinder, measure out mL of water for each beaker. Place the eggs in the water solution, cover and let stand 24 hours.
On day 4, record the observations of the egg from the water solution. Carefully remove the eggs from the beakers, gently rinsing them off. Mass both of the eggs. After the teacher has came and looked at the eggs, discard in the proper place. After two days, the shell was completely removed.The Maple Syrup Experiment My husband has always been interested in how they make maple syrup.
Over the last few months, he has studied how they do it up north and the type of maple . The corn syrup is mostly sugar.
It has a lower concentration of water (25% water) than the egg (90% water). To reach equilibrium, osmosis causes the water molecules to move out of the egg and into the corn syrup until both solutions have the same concentration of water.
The outward movement of water causes the egg to shrivel.
In this experiment we will use an egg after dissolving its shell, so it will act as a cell with selectively permeable membrane, then we will measure the effect of placing it in different solutions with different concentrations like distilled water, vinegar, maple syrup (Independent variables) on the size,circumference and weight of the egg (dependant variables).

Also, applying properties hypotonic, hypertonic, and . Mozzarella cheese In America today, mozzarella is the cheese of choice for pizza, lasagna & other baked Italian-American dishes.
When the egg was placed in a syrup solution, the solution became hypnotic with water, and since there was more organic molecules besides water, the egg had undergone diffusion, causing the egg to receive most of the molecules and shrink. In this experiment we will use an egg after dissolving its shell, so it will act as a cell with selectively permeable membrane, then we will measure the effect of placing it in different solutions with different concentrations like distilled water, vinegar, maple syrup (Independent variables) on the size,circumference and weight of the egg (dependant variables). • corn syrup • water • a big spoon: What Do I Do? 1. Put one of your shell-less eggs into a small container and add enough corn syrup to cover the egg. Put another egg in a small container and add enough water to cover the egg.
It Italy, mozzarella has a long and venerable tradition. Originally made by monks from buffalo milk, this soft cheese can also be made with cow's milk.
