When water is transported from the roots to the mesosphere cells in the leaves, it is evaporates out the stomata, called transpiration, to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomata open to release water, it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis. The water absorbed by the roots is moved…...

The step by step process was used by the software so that we could see the different kinds of reactions. According to the data found, we found that with high molecular weight compounds are too large to penetrate the molecular weight cut off pores and no simple diffusion can occur.

Osmosis is the dispersion of water. Our cells are capable of absorbing nutrients because, the cell membrane is selectively permeable (some molecules can effuse freely through the membrane while others cannot). In this experiment we used dialysis bag as a model of the cell membrane. Our hypothesis was that the glucose will diffuse out of the membrane into the beaker filled with iodine solution. To demonstrate dialysis tubing we used water, starch and iodine. When starch and iodine react together…...

Kinetic energy, a root of energy stored in cells, causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water likely. Water potential…...

Living organisms tend towards balance with their environment. Cells achieve this through diffusion. This is the random movement of solutes from an area of higher concentration to lower concentration. Osmosis is a special case of diffusion. Osmosis is the movement of water through a selectively permeable membrane. During osmosis, water molecules diffuse through the membrane from a region of higher water potential to lower water potential until equilibrium is reached. (1) In this lab, the idea was to see how…...

Salt marshes are intertidal ecosystems, surrounded by land and open to the sea by way of an estuary (Pomeroy & Wiegert 1981). As a result salt marshes are constrained, by silt and saline water, to the type of communities it can sustain (Ranwell 1972). However because of the tidal nature of these ecosystems and the presence of many migratory birds we find some of the the most widley distributed plant species in the world (Ranwell 1972). The habitat is typically…...
