Title: LAB 7 CELLS
Description: A study of the cell, the fundamental unit of biological structure and function. An introductory section on bioenergetics and biochemistry lay the groundwork for the consideration of the cell through a modern interdisciplinary approach. The course examines the ultrastructure of the cell and of the most universal cell functions: transport, cellular respiration, photosynthesis, cellular reproduction, and protein synthesis. Lecture themes are illustrated in the laboratory. 3 hours lecture/2 hours laboratory

After sprinkling sugar on a fresh apple slice and letting it sit for an hour, we can see that the
apple has dehydrated
...
The direction of the water molecules moves both in and out of the dialysis bag depending on the
temperature
...
The influence of temperature on the rate of osmosis is as follows:
Cold- Pores are more restricted, the rate of osmosis is slowed down
...
Hot- Pore are opened wider, the rate of osmosis increases
