Why is osmosis important for all living organisms? How are diffusion and osmosis important to cells? Define the term osmosis and give some examples in both plant and animal cells where it is applicable. Describe the effects of a hypotonic and hypertonic solution on plant cells. Why are ...
Osmosis is the diffusion of what substance through a cell membrane? What are the major ions that contribute to membrane potential and how are they distributed across the plasma membrane? How are the concentration differences maintained? Why does osmosis require a semipermeabl...
Since a solute will not move in osmosis, how can the space between plasmolysed cells be filled by a hypertonic solution? Biological membranes are said to be selectively permeable (or semi-permeable). What does this term mean, and how does this affect the way tha...
An ecosystem is a community of animals, plants and other species that work together and interact with the non living component of environment. The ecosystem consists of abiotic factors (temperature or humidity) and biotic factors (plants or animals)...
Why is it important for the cells in the lungs and digestive tract to be simple instead of being stratified? Why do all of the biological processes in our body occur in basic conditions (pH = 7.4)? Why is osmosis important to the human body? What is the purpose of the villi in the ...
In order for this movement to occur water must first enter the plant. Roots have adapted to this purpose and have many fine root hair cells that...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
What is a transport process that does not require the expenditure of cellular energy? What is transported across a membrane during osmosis? What are the the vascular and transport systems in plants? What biogeochemical cycle involves transpiration? What specialized structures in vascular plants transport...
How does osmosis occur through the plasma membrane of cells, which is hydrophobic?a. Fully explain the mechanism of the polarization, depolarization, and repolarization of the cell membrane. b. Explain the role that the Na^+/K^+ pump and the ion channels play in...
