When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane. This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement of substances across the cell membrane without any input of energy by the cell. The energy for passive transport comes entirely from kinetic energy that the molecules have. The simplest type of passive transport is diffusion, which is the movement of molecules from an area of high concentration to an area of lower concentration. Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space. Osmosis is a type of diffusion in which water molecules move down the concentration gradient.
When the concentration of solute molecules outside the cell is lower than the concentration of solute in the cytosol , the solution outside is hypotonic to the cytosol. If the concentration of solute molecules is higher outside of the cell, the solution outside is said to be hypertonic. The solution outside is isotonic if the concentration is equal on both sides of the cell membrane.

Science teachers don't like students to include human errors in evaluation part of lab report because it is common sense that human errors can occur.
The average epithelial Onion Cell is 30.2 to 35.4 micrometers in diameter. I just did this exercise in cell bio lab.

Lab Report was created in 1989.
The normal lab values would be a constant in a lab report.
It is very likely some people have a completed lab report on Lab, but their names have not been made public.

Conclusion is essential in a lab report because it summarizes the whole research paper.
A LAB stands for a researched report on a topic.
