To fill:
The correct term in the given blank.
Introduction:
Cells, the smallest living entities, are the living building blocks for the immensely complicated whole body. Thus, cells are the bridge between chemicals and humans. Ultimately, all body functions of a multicellular organism rely on the collective structural and functional capabilities of its individual cells.
Answer to Problem 1RE
"The barrier that separates and controls movement between the cell contents and the extracellular fluid is the plasma membrane."
Explanation of Solution
The plasma membrane is a thin membranous structure that encloses each cell and is composed mostly of lipid molecules and studded with proteins. This barrier distinguishes the content of the cell from the cells around it and prevents the fluid inside the cells from mingling with the fluid outside the cells.

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
