Answer:
Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible. For example, it has been estimated that an amount of water equivalent to roughly 100 times the volume of the cell diffuses across the red blood cell membrane every second; the cell doesn't lose or gain water because equal amounts go in and out. There are, however, many cases in which net flow of water occurs across cell membranes and sheets of cells. An example of great importance to you is the secretion of and absorption of water in your small intestine. In such situations, water still moves across membranes by simple diffusion, but the process is important enough to warrant a distinct name - osmosis.
Answer:
Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular. Eukaryotes are differentiated from another class of organisms called prokaryotes by way of the presence of internal membranes that separate parts of the eukaryotic cell from the rest of the cytoplasm. These membrane-bound structures are called organelles.
In eukaryotes, the cell's genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes. Eukaryotic cells also contain other organelles, including mitochondria, which generate energy; the endoplasmic reticulum, which plays a role in the transport of proteins; and the Golgi apparatus, which sorts and packages proteins and lipids for transport throughout the cell. Plant cells additionally contain organelles called chloroplasts, which are used to collect energy from sunlight.
