While molecules in diffusion move down a concentration gradient, molecules during osmosis both move down a concentration gradient as well as across it. Both diffusion, and osmosis are types of passive transport, which do not require help. When the concentration…

I then compared the three volume measurements and provided observation. The ext experiment was to determine the effects of salt concentration on bacterial growth. The tubes of broth were labeled as directed and antiseptically inoculated with the appropriate organism, and…
Diffusion and Osmosis Lab Report Assignment
We therefore concluded that only small molecules like glucose and iodine can permeate through the bag, starch is too large. Introduction This lab has several key objectives. First, to learn about diffusion and osmosis, and the different factors that affect…

The process of Natural Importance Introduction Osmosis is when a fluid passes threw a semi permeable membrane. Moving from an area in which a solute such as salt is present in low concentrations to an area in which the solute…
Lab Report on Osmosis Assignment
The other is called passive process, which does not require TAP energy and the transport process is driven by concentration or erasure differences between the interior and exterior of the cell. All molecules are in constant motion, ergo, possessing kinetic…

When the solution is hypersonic, the potato Will decrease in size making the potato hypotonic. Osmosis is really interesting, that is why chose to write this report about it. Materials and Methods We first cut out six cores out of…
