has a low concentration of water. Therefore‚ the water will travel from high to low concentration. The sucrose in bags 2‚ 3‚ and 4 are hypertonic to the water inside the beaker. Adversely‚ the water inside the beaker is hypotonic to the sucrose inside the bag. Another example to this would be swimming in the ocean (salt water) where the ocean’s water is hypertonic (lower water concentration) and the human body is hypotonic (higher water concentration)‚ causing the water inside the human body to move

Abstract The purpose of this experiment was to test different solute concentrations on the rate of osmosis. Artificial cells were filled with different solute concentrations and placed in water and weighed at equal time intervals to show how the water moves across cell membranes and down its concentration gradient into the lower concentrated area. The weights of the cells were recorded each interval‚ and then the rate of osmosis was found by calculating the corrected cumulative change in weight

HYPERTONIC SOLUTIONS The word "HYPER" means more‚ in this case there are more solute (salt) molecules outside the cell‚ which causes the water to be sucked in that direction.

If it’s fluid being taken in – pinocytosis (cell drinking) or if it’s solids - phagocytosis (cell eating). endocytosis hypertonic Red blood cells in different solutions: hypotonic isotonic hypertonic Types of active transport: concentration gradient Osmosis is a special type of diffusion‚ where water moves across a selectively permeable membrane from high water concentration to low water

Julia Babin Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

It is hypothesised that when sheep’s RBC are added to a hypertonic solution‚ they will shrivel and occupy less space within a haematocrit tube‚ when compared to a hypotonic solution that will cause the cells to lyse. Materials and methods This is the description you gave of the materials and methods you used

pressure (the pressure created by the increase in water pressure within the cell) in plant cells. Turgor pressure prevents further osmosis‚ which causes the water potential outside the cell to be lower than that inside the cell. When placed in a hypertonic environment‚ the gradient in animal and plant cells are reversed and water exits the cell. This sudden release of water results in a shrinking membrane‚ called crenation‚ which

Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We
