Answer:
The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.
Explanation:
The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water. In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.
I hope this can help some.
During the long voyage Darwin made many observations that helped form his theory for evolution. He visited tropical rain forests and other new habitats where he saw many plants and animals he had never seen before. This impressed him with a great diversity of life. He visited rock ledges that had clearly once been beaches that had gradually built up over time.
